actually when I tried these 2 engine oils, my fuel consumption still the same LOL

Use 30 if your car is new. Cause the thick oil of the 40 in long run will be higher chance to clog up the engine oil sump.

true

I'm using 5w40 on my Exora turbo with only 45K on the clock, but using full synthetic.

Because although 10W30 is stated recommended in the owner's manual, I still put abit thicker for added heat protection. Just my opinion.

Nothing against thinner oil. FC wise, almost the same as 10W30, maybe because its a heavy car and plus my right foot is abit heavy playing with turbo boost.

Where is the source that proves 5w-40 lubricates and protects the engine better? Hehe.

Can share how did you arrive with this perception?

Use what ur car’s manual recommend, they have done their tests to see which is most suitable. Personally I prefer w40 , engine feels smoother, no significant loss of power or fuel consumption.

5w30

Amsoil SS
Miller CFS

Hehe hehe. Premium

I've tried both and no difference in FC or performance also. I just use 5w40 coz easier to get with big promotions in supermarkets. 😁

My car manual recommended 5W40... Use the same grade from day 1 until now clocking 162,000km

Thinner oil is supposed to help lubricate better during cold start situations.

follow what is stated inside your car's manual
not based on mileage
like saga BLM from the start is using XW-40

Just follow your manual. Don’t pandai pandai

agree. thicker oil offer better protection because between the engine parts may already have wider gap after using for few years, and thicker oil can coat and cling on the parts better than thinner oil.

The difference is oil pressure to activate VVT system. With thinner oil, it can travel to tiny spaces faster. Thicker oil is slower. Thicker oil resist foaming. But this is only valid for high rpm conditions.

Also thinner oil is made for new gen engines that has higher tolerances. Older does not. Thinner oil makes engine parts lose less energy due to oil accumulated weight when reaching higher temperatures.

agree! thinner oils are "lighter" which help on fuel efficiency as well.

Follow your service manual.

If they recommend 5w30, use it.

If they recommend xw20, use that.

Going from 5w30 to 5w40 will NOT give you extra protection if you use it under normal driving conditions. However, if you use on the track, yes. When temperature is raised considerably, a w40 will behave like a w30

Using a thicker oil will waste petrol. How much you ask? up to 3%

Newer cars are calling for thinner oils, x-w20 oils, some even x-w16

Use the right oil, save the environment

Apparently Toyota already started using 0w-16 in Japan. Yeap. Zero W Sixteen. I could imagine how thin the oil is when its at 100C.
No doubt it will definitely help fuel efficiency just that it gives me the cringe about how it will perform in our hot climate.

here is an article about fuel economy vs thin oil, written by Specialists:
https://www.machinerylubrication.com/Read/518/motor-oils

But I believe engine manufacturers aren't just simply using 0W-16 without compromising engine reliability.

Because in the eye of most consumers 0W-40 is superior than 10W-40. That is why it more expensive.

The manufacturers, based on years of experience, it is very unlikely that the engine going to fail other than more on common wear and tear. So, by using more expensive oil they can get higher margin

Done read it, so conclusion is still a little bit of "thicker" engine oil like 10W-30 or 10W-40 still provide promising protection than thin engine oil.

no won't happen, unless you don't change the engine oil to the point it has broken down to sludge. Technically, there's no way in clogging up the oil sump as it just serve as a tank.

But sludge can indeed clog up lubrication channels within the engine.

Concur

Only the front number indicates the lubricating properties during cold condition. In the above case, both oils are rated 5w, so the cold start performance are similar during cold.

For it to matter when w40 makes a real difference compared to w30, the engine has likely been modified to face with really high component contact pressures and RPM loads.

For normal run of the mill stock car (mildly modified included), if the manual states can use xw30 or thinner, it means it will work with that viscosity rating. Spirited daily driving hardly stresses the oil to the point that was faced during lab test conditions to derive the specification.

As a matter of fact, pumping RON97 has more direct impact towards engine oil health as the higher sulfur levels in RON95 will eat into the acidity regulating additives at a faster rate. If the oil has gone "sour", the sulfur will react with the water content in the air and within the oil itself, creating sulfuric acid which really eats into the metallic components.

It will still remain w40 unless there's high levels of fuel dilution....what kind of oil is this that can't remain temperature stable? I guess a more appropriate comparative statement to what you're saying should be "....behaving like w30 at 25C"

Just so you know, i made that temperature level up, i don't know that exact science, but just a more appropriate clarification.

I have seen some people judge the oil quality by the "price tag" which is ridiculous.
Especially when it comes to the debate about the Shell Helix Ultra sold by Giant and Tesco at super cheap price. Some people claimed its a recycle oil underneath Shell bottle just because of it's unusual cheap price, when I feel its not.
FYI for Shell Helix Ultra sold in Giant or Tesco, they are parallel imported genuine Shell oils from European countries. I've seen some batches made in Italy, Germany and Turkey .

Anyway back to the discussion, wkc5657 has replied and explained very clear. Job well done, wkc5657.

To add, actually viscosity of the oil is measured in CentiStroke (cST) but tell that to an ordinary Joe and he will be confused. an ordinary Joe only knows "5W30" is thinner than 10w40.
thats why the best way is to google up for the product Technical Data Sheet and see what cST the oil is having at 100C.

@wkc5657

Disagree, when you track your car, the oil temperature exceeds 100 degrees C.

Oil thins out when it is hotter. So a w40 at say 120C may behave like a w30 at 100C

Hence, when one is going to track their cars, typically manufacturers recommend a thicker oil.

For normal day to day usage, most engines run at 100C. When you track your car, it exceeds that.

Nowadays, newer cars recommends 0W20 oil. So if you guys want a thicker oil, the 0W30, 5W30 or even 10W30 should be sufficient to protect your engine in our hot climate.

The 5W40 oil are meant for older cars made in the 90s to early 2000 like Wira, Corolla, Perdana as it was the recommended oil back then.

For racing application, usually they will use a heavier weight oil like 5W60 as the oil will thin out under extreme engine temperature. Anyway, this grade of oil is not suitable for daily driving.

Even if you track your car in stock form, provided that you maintained the car reasonably, unlikely it will not overheat the engine oil. The faster you go, the cooling circuitry also works harder correspondingly. The added velocity of air also draws more heat away from the radiator and other heat sources.

It is very hard for people to accept that, unless track ALL the time or the car was purpose built for tracking/racing, if thinner oil that is within the stated spec in the manual, there would not have any noticeable ill effects (even if you track once in a while in stock form).

If you really want first hand experience, please spend some time looking through the pinned dedicated engine oil thread, very informative with used oil analysis to back up.

Also, please read have some readings valvetrain/drivetrain components and oil related articles in the "tech centre" segment of enginebuildermag website. It is quite deep for starters, but you get solid knowledge from real engine builders :

thanks for sharing

2019, and people still confused with the viscosity..
used as per what manufacturer recommend. There is reason for that.

Good read, thanks for sharing

used 40 better because our climate is hotter

To confuse them more, at 100C "a thick xW30 has almost the same viscosity as a thin xW40" (Eg 12.5 cSt @ 100C. See chart below SAE Engine Oil). You can only know the actual viscosity (cSt) from the lubricant kinematics (which is never on the bottle label).



SAE J300:
SAE 30 spec: 9.3-12.4 cSt @ 100°C
SAE 40 spec: 12.5-16.2 cSt @ 100°C

(Edit: added SAE J300 spec above)

My kelisa using w40 going to reach 200,000km soon

As usual, majority don't read the given manual. They would rather trust the mechanics that didn't read the manual too.

All based on some one say so.

One can't go wrong by following the recommended engine oil as in the manual.

My Odyssey RB1 - use 10W-30 since day one (bought new in 2005). Clocked nearly 180,000km. Oil change every 10,000km as recommended. Still silky smooth as day one.

mine clocking 130,000KM, have being using different grade and brand of engine oils and still maintain great engine performance with good fuel efficient (16km/l).
as long as we change the engine oil on time, and use genuine EO, that shouldn't be much issues.

Exactly. Some engine can take different viscosity. 10W-30 till 50. No harm. Manufacturer knows best.

That is why manufacturers give a range instead of giving just 1 specific viscosity.

The engines are quite over engineered in some sense as no single driver's driving conditions and habits are exactly the same. And to cater for international markets with the same engine engineering, it has been built robust for quite a large range between 2 extremes (especially japanese car engines).

Here's the deal to all that still want to stand on viscosity is the main considering factor for engine protection. The real take is changing the oil more frequently can better protect engine internals. This situation will never allow too much contaminants to build up.

***handshake***

My car clocked 230k km and using 0W20 better feel and huge different in fuel usage after remap.. Up to u only what to use.. See manual and normally got tolerance..

nice sharing!

The margin is quite small.. almost similar thickness.. as for me just use recommended viscosity from factory.. the engine design for that

by your logic then, we should only have ONE type of viscosity to meet this climate.
I hope the distributor can see this as an opportunity to streamline their offering. might focus on one spec from now on. less variation. clever

Go and read engine lubrication 101 first. Why in Saudi, there's still 10W-30. W - winter, 30 - thin oil. They should use xx-60 then because their average temp always above 40C

From 10k - now 110k km, my car was with honda 0w-20. No problems whatsoever on our climates.

Just that personal feelings the oil lose it smooth feeling after reach 7k onwards. But still proceed with every 10k km oil change

its actually the same bottle in Giant sold also in Shell petrol stations (only difference is the sticker label, thats all)

It means the below requirement:

Which means anything below Merc BMW, it exceeds the standards

This post has been edited by pcdoctor_my: Apr 5 2019, 04:51 PM

just follow whatever recommended in your service manual
most car will be fine with 5w-30,going up or down one step in viscosity usually is still within factory recommended range and won't affect anything.
factory provided lube is mostly base on "normal" driving behavior,prolong thrashing the engine and track driving are not include in the "normal" parameter,you'll need to use appropriate oil for that

for my car Mercedes recommended 5w/40 suitable for our weather, Syntium 3000 5w/40.

Aside viscosity .the brand also kinda important .

It may have same grade but during stress test on the oil show differences

sure some oil are better than others but as long as they meet the API and ACEA certification, the minimum performance will still meet your engine requirement
the only real risk is counterfeit oil, which... don't even mention what API ACEA certification la...might be just used cooking oil from char kuey tiow stall

yeah...especially those selling @ supermarket/hypermarket.

i have once make an inquiry to respective brand about it. The reply i got was buy it at your own risk and is not from them.

Then i wonder is it even legal? is there any enforcement checking on it? the price of it seems too good to be true.

i would argue otherwise
in term of probability, it'll be foolish and low possibility for multi million supermarket corporation who had everything to lose if they been caught selling counterfeit stuff just to earn the small profit from engine oil section
they had their products displayed in front of millions of shoppers which includes their competitors, other oil suppliers,and even Shell or petronas staff to examine, if they sell fake oil they'll be caught in 5 seconds, they won't survive selling fake thing for so many years now.
but different stories for small individual parts store outside, they always stow their products behind the counter unless you want to buy, they can change their inventory very fast to cover up,they're relatively small and selling fake stuff provide them big profit, and they have relatively nothing to lose, i would be more wary of these stores than supermarket

While some of your statements are true, but would it make sense that Shell Malaysia issue a statement saying RRP for an oil is say RM280, and a hypermarket can sell it at RM99?

That doesn't make sense. Either the oil is imported illegally or it is leaning towards being a fake.

Also, Shell Malaysia has highlighted that their oils can only be sold through their official channel.

Imagine, Apple sets RM3999 for iphone Xs Max. Giant sells it for RM 1999, will you think it is fake?

You're not driving super car. I don't see the issue using any of both...

This post has been edited by danielmckey: Apr 8 2019, 08:48 AM

all the while I am using 0W30.... Last week i sent my car to service... The technician recommended me to use 0W40. I think it is becoz my car has clock more than 100K km. Currently 116K.

I feel no different like what u say... FC wise, I need to monitor and share here later

I would concur with Valentino's general comment, and am of the opinion that RM99 Helix Ultra from Giant/supermarkets is not fake (as like being adulterated, out of spec etc), instead it is genuine made in EU .
Shell Malaysia could have imported from same EU source and sell it at RM500, much higher than made in Malaysia SHU! ..... what a bs from Shell Malaysia, IMHO.
Thank you, Giant management.

Because Shell Malaysia tacks on a steep markup?

Giant and Tesco imports the oil directly from Europe without going through the local Shell distributor, which made Shell Malaysia unhappy and launched a anti-fake oil campaign ( automotive blogs, billboards etc.) trying to steer consumers to buy their EO from their official channels.

Why did you think they went through all the fake oil PSA brouhaha, but stopped short of straight up calling out Giant/Tesco for selling fake oil?

The oil is legally imported by Giant & tesco. Its already confirmed by Giant via its circulation letter (I saw it posted in FB, cant find the link now)

And that makes shell Malaysia unhappy. Because they it affects their overpriced oil sales. Hence they put up this threatening campaign.

Take this scenario - a handphone. We all know that there are AP sets and there are authorized sets sold by Malaysian authorized dealer. Both are genuine stuff. Only the authorised set is sold with full warranty by the authorized distributor. But much more expensive.

AP sets are parallel imported from overseas by shops. Same model but alot cheaper. Only difference in warranty between both of them. Warranty by the shop, not by the authorized distributor.
But functionality,the AP still works the same as the one sold by authorized dealers. And not illegal either.

Same goes for recond cars, though thats abit of a different situation.
UMW sells their brand new Vellfire for like 350K whereas a 2016 unreg recond Vellfire is around 250K (depending, im just quoting example) . One is a brand new car with warranty by UMW, another is a "Old" new car with shop warranty.

Consumers are attracted to price. Cheap price wins. Who doesn't love cheap bargains.

Im not trying to argue that I am right. Im just explaining what it is.

most Malaysians are too accustomed to malaysian automotive over priced products that they thought the high price should be normal
if you think 99 bucks is cheap for 4 litre, America had it cheaper and much more options to choose from and it's cheap all year round, no need wait for promotion, that's the real price of engine oil, petrol station here are ripping the shit outta our pocket.
the other automotive item that we're being ripped off with insane margin is car care products like turtle wax or meguiars

This post has been edited by Valentino46: Apr 8 2019, 02:22 PM

To be fair, everything is cheap in the US, especially when it comes to goods (cars, shoes, groceries and etc.).

Try comparing to HK or Singapore and even Europe. If their prices are much cheaper than Malaysia, I will concur with you.

Dont pick US, most things are cheaper there. Especially if it is made in there or an American brand.

I just came back from Japan recently, and pricing of oils are about the same as Malaysia. Been to a few other countries, US definitely 30-50% cheaper for oils.

so why shell malaysia no sue hypermarket?
can get a lot of money yo!

will appreciate bros here to refrain from convincing others that the bargain oil at hypermarts here is genuine. It is a lose-lose situation.

No point convincing them and end up more competition in sapu stock. It is already difficult to catch hold of stock during sales as of now.

So pls yeah..... think b4 you argue/debate on the internet

free market should always be our benchmark to compare price, not heavily taxed country which had the price muddled beyond useful comparison.
if product are the same, intrinsic price should be the same, the price differences are in tax and margin on top of the base value.
i encourage people to question and examine more of the pricing mechanism rather than accepting whatever price the seller or gov like us to pay, it's sheep mentality

This post has been edited by Valentino46: Apr 8 2019, 07:00 PM

if too many uninformed people willing to buy the same engine oil for double the price, it might create an upward pressure on the supply side which allow for dealer to raise the price.
imagine you're dealer, you want to sell your product at market who pay you double, or half the margin?
free market require all market participants to be reasonably informed to be effective

Why dont Marvel sue hypermarkets for fake Iron Man tees? Why dont Nike sue pasar malam seller/ distributor for replicas?

Ah well, i think we are getting off tangent here.

Oil genuine or not, nobody can know without proper testing.

Use what you must.

Back to thread starter, follow what your Owner's manual recommends.

In theory, 5w30 should save up to 3% in FC with comparison to 5w40. Assuming both have the same ACEA or SN spec, both should provide similar protection

While in an ideal world, I would agree with you. However, we live in Malaysia, prices for cars and products are skewed based on different taxes and structures. Shouldn't we then compare based on what we have here?

I agree with you, we should make comparison based on world standards, but in Malaysia it is different.

Anyways, excellent feedback. Constructive feedback is always appreciated

Did you all notice that only Shell Malaysia put "Untuk Pasaran Malaysia" ?
Why don't Shell China claim "Only for China" ? Lol

shell malaysia is a joker.

so is new Shell Helix HX8 better than Shell Helix Ultra? I think Ultra shall be the topmost range from Shell right?

because big hypermarket aint another pasar malam stall
apple don't sue pasar malam stall for selling their replica item because you can't get any money outta them but it sure sued the shit outta samsung right,if tesco/giant do fake shell can sued them for lotsa damage compensation.
its not easy to get away with wrong doing being a big public corporation
honestly,if petrol station wanna sell you fake thing oso can,even louis vuitton had that in record,but the probability is quite low

shhhh...they just wanna protect their delicate 100% margin profit,let them have fun bruh

I have met a mechanic once challenge me back... how do you ensure the 3rd party distributor which Giant/Tesco get stock from, does not swapped with fake oil? I think this forum some thread back saw somebody posted the photo of the engine oil with the 3rd party distributor sticker...

found it here, refer post #3991

Yes, Ultra beats the HX8 ........ though it works the same for all Asian cars here .

if you ask back the mechanic how he ensure his oil supply not fake then,the reply usually is "trust me bro"

This makes it unique mah...

Malaysia truly Asia...try beating that

yeah, he told me "trust me bro, you use semi syn oil from my shop, FC could be improved on your Gen2 which you used source unverified Aeon Big Castrol Magnatec 10W40".

There is another one. Lagi so-called higher than Helix Ultra.
Its called Helix Power. Not V-Power. Helix Power.

Source: https://www.facebook.com/groups/CFEnCVT/per...568974/?app=fbl

and this photo aint fake either. Someone took a photo at a Shell station right here.

Wtf is the difference between Power and Ultra i dont know.
Except for the price. And its also Limited edition . Sounded so exclusive this Power oil .

its not even on Shell's website !

it's written with Shell V-Power! This could be the engine oil made for F1 oil burn technology for extra party mode!

6UE5T can't believe this is available in our market. I guess only those oil burning Audi, BMW can utilize the advantage of this!

Hahaha you're following too much F1 already! 😂

Yes you got it right.
The Chinese words mean "For HK/Macau market only".

yea, EO don't really effect much as long as we are using within the range of the spec

You so slow ......shell Malaysia already acknowledge about giant/tesco selling shell Helix ultra but didn't dare deny nor confirm it's fakes .they come out with the usual statement" buy from our authorize station to enjoy the warranty of our product ".btw who has ever claimed from the so called warranty ?
Usually those people come out with statement "I can't confirm nor deny" have secret to hide .

In response :
At first, they change their sticker Abit with the word .....market for Malaysia.

Newest trend :
Now they come out with brand new packaging with new name but with such similarity to old design packaging but with price reduced .(something funny indeed,within such a short period of time)

This is selling way below recommended price ?just did a quick search.any comment on that?


This post has been edited by TRAZE99: Apr 19 2019, 02:53 AM

HX8 is one tier below helix ultra series, so priced cheaper

Shell rotella is best series of shell line of full synthetic engine oil. But Msia no sell lazada no sell

Rotella is an American thing.
Outside America, Shell markets Rimula instead.

I will avoid buying Shell engine oil from authorized distributor due to its expensive pricing. No harm buying from TESCO GIANT if these Shell oil are priced right.

Not to mention the billions of dollar went into sponsoring Ferrari F1 throughout the years. Buyers will end up paying for these sponsorship through expensive engine oil price.

This post has been edited by Thrust: Apr 20 2019, 09:50 AM

exactly, that is how we actually paying all these expensive sponsorship fee to this big brands around the world.

no people here using Liqui-Moly brand engine oil?

Been using Toyota 5W40 full synthetic since day 1 when i get my Vios dugong. My fuel mileage remains the same till now 2020 no change which is about 450KM.

It's always a good idea to stick to the manufacturer recommendation because the specific oil is tested for specific engine that it will not harm/ disintegrate the seal/ gaskets/ O-ring whatever inside your engine system. Certain old cars cannot use full synthetic oil not because of the piston tolerance or whether it's a thicker or thinner oil, it's simply because the newer oil might damage the seal causing leakage.

My car comes close to 10 years and still going strong. smooth ride and no drop in mileage. I do EO change every 10Km sharp.

I recently found out sellers are selling dirt cheap Toyota 5W40 engine oil in Shopee, and i'm not sure if those are fake. Toyota dealers sell at RM160++ minimum and they sell almost half of dealer price.

Has anyone ever purchased Toyota EO from Shopee/ Lazada with super cheap price? Any comment/ observation? Any constructive answers would help to make an informed decision for potentials buyers in the forum. I myself always get the spares from Toyota dealer like ST AUTO SPARES or VANLI to be safe but pay a little higher. Also can anyone share if Malaysia Toyota oil is manufactured locally or import? Could that be parallel import? I saw what's written on the label is "Buatan Malaysia" even the cheap one sold in Shopee/Lazada so i doubt it's parallel import most probably fake.

THX.
