aeon topvalu fully synthetic 5w40 i bought RM99 last time..
it was locally blended oil listed under API official licensee directory. you may ask "can trust or not? boleh pakai? will my engine kaboom?", well, it's up to you..
https://engineoil.api.org/Directory/EolcsRe...dName%3Dtopvalu

but i don't know if your engine condition still good enough (no oil leak, no oil consumption) to take fully synthetic and lower viscosity oil. If engine condition already bad and use those oil without rajin to check oil dipstick, you may end up with less engine oil and having risk of car breakdown on roadside...

Tesco brand is good enough if you are on budget.

If engine condition not that good, the car can't take fully synthetic or lower viscosity oil?

Expect oil leak occur on oil seal area, piston ring let more oil escape into combustion camber and burn together with air fuel mixture... What engine oil you have been using all this while? Any oil consumption or oil leak?

10w-30 oils are mostly full syn. Tesco semi syn is 10w-40.

I've been buying Engine Oil from Tesco mainly over 2 year.
Both my car now running with Mobil New Life 0w-40 bought when promo RM169.

No issue with it, in fact the engine runs fine & smoother.

If you have budget around RM149, plenty choices you can option to Shell,Total,Castrol & Penzoil brand.
Of course with promotion period.

Budget of rm100 can get you FS oil la if you're smart enough to find good deals! Just a month ago Jusco had promotion for Mitsubishi Eneos 5w40 FS oil for just rm99/4ltr! If you search in mudah, there are plenty of those oil selling around rm90+ only. If just want semi, should be able to get just around rm70 or less.

Not really, 10w30 is usually semi. 5w30 is mostly FS.

Eneos 5w30 (Eco Touring) - Made with synthetic blended base oil... is a semi synthetic oil?
http://www.eneos.my/us/introducing-eneos-motor-oil/

In the Eneos website, the 5w30 is fully synthetic oil

Currently, I am looking for 5w30 oil for Mit Mirage, not sure the Mit SC is using 5w30 semi-synthetic or fully-synthetic

Eco Touring is a semi synthetic oil.

Thanks for your confirmation.

Just curious, mine Mit Mirage is 10,000 km interval service, semi synthetic oil can last 10k?

No confirmation on this unless you send your oil for UOA.
Some drivers believe their engine is just as well protected by mineral oil for 10K OCI, so ultimately it is your personal preference.

If the Mirage is multi port injection, 10k km is doable I suppose.
Though most would settle at 8k.

This is confusing, i am not sure which type of oil is better ? 10w40 ? 20w50 ?
The front number represent the viscosity of the oil when it's cold , the number behind means the viscosity of oil when it's hot ?

Did you read your owner's manual? It tells you what oil viscosity (like the 10w30, 15w40, 20w50 grades you can use).

You got the second sentence right the first number stands for Winter, and the number behind represents the viscosity during operating temperature (hot). For more info, watch this, really good info on viscosity and synthetics vs mineral oil.

I don't hv the owner manual..... I am not the direct owner of the car....

Thanks mayalab & zeng.

Will do a last service at Mit SC (70k km) this week and look for other cheaper service centre in the next service.

Just go for 10w40. If no oil loss then keep using. Otherwise, go for 20w50 on next oil change. Just make sure you are not getting fake/recycle oil. Get from hypermarket or petrol station if you are not sure.

OK， Do you mean if the engine gt 'consume oil', then go for cheaper 20w50?
