yes they do.
motorcycles, differentials, machineries, aviation etc

you could probably analyze cooking oil if you're really adventurous and got money to spare.
see how much sodium, iron and Calcium your fried chicken used frying oil contains

jokes aside, i've got few gear oil samples in my first page, and my friend has finally contributed the first LSD sample for everyone that i'll be posting soon, ish.
(life gotten super busy for me this year)

BOLD oil on shoppee already got their API Certificate.

Now should be more confident to try

So far so good. Paulhew is selling genuine oil. They have a physical spare parts shop called EC Auto at Batu Caves area.

Hi, saw u write Paulhew here so i write some review bcos i just bought engine oil from him.

I feel his engine oil is not original, although got code at the front sticker.

1. Smell like used oil from engine and different from original oil smell. Can said is like recycle oil or original mix recycle oil.

2. Color is darker compare to original.

3. Side bottle indicator design is different.

4. Handle of bottle is different.

5. Back of bottle closure is different.

6. Bottle seal is like hard paper, original is foil.

No offence. He sell RM60++, so maybe all cheaper price oil is not original

Why not upgrade using 5w40 fully synthetic, rm90+ at tesco. Or Aeon also got Mitsubishi 5w40 similar price range

Your Helix is with Thai wording at the back of the bottle?

If it is yes, the bottle and also the oil colour and smell might vary from the Helix HX5 'untuk pasaran malaysia' since they are blended and packed from different manufacturers.

I am not sure of engine oil from Thailand uses recycled oil.. But according to some forumers here, European Union mandate the use of recycled engine oil to be blended into new engine oil.

I'd normally for for the 'untuk pasaran malaysia' since in Malaysia, there's no mandate to use recycled engine oil, thus all engine oil base  used in Malaysia should be new and not recycled.

Hi, my car is old car and engine got leak oil problem.

So cant using light weight oil.

Cos last time got use full synthetic oil also, but very fast the engine oil empty ad.  

Any one experience this after new oil change car feel more power ? Literally first time experience this .

Ya. It is true. Every time i change new oil got this feel too.

When tekan minyak is like more smooth and powerful.

But after awhile it will go back the same ad.  

Any one experience this after new oil change car feel more power ? Literally first time experience this .

It is normal. Maybe the previous oil change u over extend it hence engine feel lacks and heavy. After change eo, feel light. What car btw? Try follow manufacturer recommended viscosity, hate mechanics give wrong advice once mileage getting high, need to put heavier viscosity eo, hence unable to get as previously FC

Then u should send repair the leak first. It is not normal. Valves Gasket change perhaps?

Before this after change no rasa one. Tried many brand before same thing. Now this chiplak brand one got this effect , car feel more powerful after 6kkm only back to old condition.

Chiplak is a engine oil?

Can tahan 6k then ur one better o...

My one like 2 or 3k ad no feel ad...

Ya. True bro.

I got plan to repair this soon.

Cos not reach mileage to service my engine oil ad empty.

Ya, I heard ppl said normally is valves gasket issue.

So if no leaking issue then can use fully synthetic oil?

if it me, these are my things I done.
1. Fully synthetic EO, 5w30
2. Transmission Oil change due to mileage
3. Brake pad new
4. Tyre all new.
5. Fuel spray cleaner, done it diy. myvi easier. https://www.mrdiy.com.my/default/aeropak-ca...-9001984-001001

open the air filter box, remove the air filter, switch on the engine, ask somebody to put rev to 3.5k - 4k rpm or if Diy, but brick at the pedal (make sure Gear at N - manual, handbrake on), spray this no 5 slowly. There will be a lot of smoke later possibly to clear out any junk? but from my own experience, the car becomes really light after spraying that.
