I will still avoid those cheap oils. Not sure what they put inside and will it impact in the long run or not.

Its like buying vegetables full of pesticide vs vegetables that didnt use any pesticide, both meet the requirement/approval for human consumption, but only god knows what will happen in the long term.

I am still skeptical on this. Engine deterioration is not something that you can see immediately.

Its like someone who keep eating maggi mee and processed food like sausage every day and keep telling: see, i eat it everyday yet i am still healthy and no impact. But maybe after 5-10 years, or maybe more, the impact will come. And by that time, its already too late.

For me, nothing can escape from the general fact of life: you get what you paid for.

if you understand chemistry
engine, physic, and math.

You dont kecut bola with Oil.
1. Fully Synthetic ONLY
2. SEMI = scammed ( not all semi is 50/50 i think )

Reason :

Synthetic Oil paid for itself.

Miniral, Cheap oil for those finding trouble.

Dude,  those are your insecurities, not mine. Dont project it on to me le.

One bought from Vanli (lazada) who insist theirs is grey import or something... another is in shopee...

Both seal dont have hologram whereas the one I bought prior from Mesra (3months or so earlier) has hologram.

May i suggest u change the old every 7k km instead to maintain your engine's health?

Its been proven 10k km oil change, no matter the oil will slowly deteriorate the engine. Only thing the car manufacturer recommends 10k km oil change because it helps in promoting low maintenance cost on the cars they are selling and the car usually will be able to last till 9 years with 10k km oil change.

Note that most car manufacturers do not think oil consumption of 1L engine oil of every old change is considered a defect.

No scientific statistical data, but the data or proof that i got are from engine builders. Some engines came in with full servicing from SC with the recommended mileage intervals but when open up there are some sludge in critical parts of the engine and generally more wears compared to those that changes oil earliers. Not sayang your engine will rosak, just it will wear out faster.
Prime suspect is the carbon buildup around the piston rings and oil return galeries on the piston which finally will cause the rings to jammed and slowly wear out cylinder walls after few k kms.

Even world expert japan engine builders says so.

Again, if u wan to use your car for the manufacturers intended use timespan/ mileage, then no problem your car will last till then if u follow strictly their recommendations.

But if u wan to keep it longer and sayang your engine then change earlier.

-------

To add on, not all cars will experience the same wear. It fully depends on usage also like if the car always long distance and doesnt get stuck in traffic, these generally have the lowest wears.
However those with over 10k km oil changes will have higher risk of developing carbons even when the owners care for the car, as shown by many engine builders when they open up to inspect the engines.
5k km oil changes have no carbon build up issues if taken care of right.

i use cheap mineral oil and change at 10k-15k interval  already 260k km

Delo 400/Delo Gold in pail.. tak main plastic bag

my car also 10k~12k, not vanilla car, but all leaning towards performance... dun care duration, always mileage.

FC is dependent very much on tyre pressure and driving style.

Only good way is you time yourself on video for the same road same distance. Otherwise even the meal you eat or haven't eaten, or whether go toilet already before testing, affect the result.
15-40 never failed 

U want continue pay iq tax ma pay la , u talk like TS force u to use bold . Fyi Merc stock tyre are worst then linglong tyre.

I think what he meant was u are shitting on bold users while we dont do the same to you.
We respect your choice, so shld u to us. Common sense.
U can point out to us if bold oil is no good with facts, but not simply perli bold users.

Latest example:
You : bold users so stingy eiiii~, no quality like linglong tires eeeiiiiii~
Me : facts i hv shown u, bold have legit certifications which exceeds my car's requirements. Also i have good experience with bold thus far

I still have 1L Bold 15w50. I guess I should give it another try since the dirty carburetor might have affected the performance. But the 10w40 really only smooth until 1000km and then starts feeling rough. I tried that one long before the carburetor needed cleaning.

Sprinta F900 and Shell Power seems to be OOS in their respective Shopee Official Stores. Go petrol station buy I guess.

Ratings:

Yamalube - Shiiiiieeeet... Sometimes smooth sometimes rough. Only reason I'm willing to use this oil until 2500km is because of the Yamaha brand. Used this oil for like my bike's first 40,000km then I realized Grab gave discount for Shell EO.

Bold - First 100km gear change from 2nd to 3rd felt rough after that ok. Engine feel smooth up to 1,000km then it starts to feel rough. I don't dare use past 1,500km. Quickly change it when hit 1,500km.

Shell Long Ride - Really smooth all the way to 3,000km like the back of the bottle promises. But acceleration is lacking. When I pull the throttle the bike doesn't respond immediately. I can feel the engine spinning up but it's not translating to acceleration.

Shell Power - the first EO that convinced me EO can make acceleration better. It's been a while since I used this because it got expensive so I decided to try other brands like Petronas and Motul.

Sprinta F900 - Smooth up to 2,000km then it starts feeling less smooth. Acceleration better than Shell Long Ride I guess.

Motul H-Tech - Smooth all the way to 3,000km and acceleration better than Shell Long Ride.

Motul 7100 - Currently testing. Already more than 1,000km. Smoothness started to feel inconsistent after 1,000km but I feel the acceleration is the best out of all the EO I've used.

Wow. I don't dare push until 4k even. I changed every 3k. The bottle said 6k but with a star saying under specific conditions but they never clarify what are the conditions. Makes me feel Shell doesn't guarantee you can push until 6k. Anyway if you wanna push until 6k, make sure you do it with a new oil filter la. 135LC manual says oil filter only last 2 oil changes or 6k.

Now not using Long Ride anymore. Been testing out various brands sold by VR Global Trading. Mapetrol Premium Power Ester was damn smooth. I will buy it again next round.

Castrol good? Saw it on VR Global Trading, thinking about trying.
Also my 135LC joined the 100k club already, so I really really don't dare to push EO past 3k anymore.

6k mileage is long for a bike la, especially kapcai somemore. Check your bike manual la, kapcai usually recommended 4k only.

Also, need see both manual and oil. Bike manual say 4k, u go follow oil 6k..dont later need push bike cry cry go bengkel.

Previously the very old bike was take care for service but use workshop oil, most of time use mineral. One time when change the oil, oil was eaten a lot and mechanic told please standby.

A month after the engine died and send for overhaul. Then stick to 2k km interval change + fully synthetic shopee oil. Either Mizu or lately Bold cz price

Isnt thjs practice of going over bike recommended intervals much worse than using cheap engine oil like bold..
Actually u can use till 10k also your bike can jalan as long as oil level is still good...but it will have much more wear and reduce your engine lifespan.

Roughly 3k km.

Damn leceh need so frequent oil change for mere 2-4k km distance.

Why not try ev bike for short distance ride?
