bro, how much u r getting for amsoil?...but 0W is for extremely cold weather for easier start-up and quick circulation...izzit suitable for our hot climate?
Frankie quotes RM160 for 4Quarts, i.e 4L equivalent, I'm on my seventh oil change... My Optra already clocked 160,000KM. Prior to that I was on Royal Purple 0w20 twice and ENEOS 0w30 from 30,000KM on my odo.
Look at it this way, oil grades always improves, last time it was just API SL, then it's API SM. Does it mean that you should stick to the older grade oil just because it was the last word printed on the manual?
I work for the drilling fluids business as a sourcing specialist at one time, and now I work in one of the smaller operators, I'd think I understand more about oils, viscosity and wear and tear better than the average man on the street.
If you want to go on using the old specced oil, it is ok, but because it is more viscous, it takes more effort for the engine to move.
My new swift which I bought for my wife, will go on Amsoil regardless what the warranty or free service offered. How can a mineral Castrol be better performing than a fully syn.
If you're well pocketed then go for Ester based oils, which in most cases are derived from vegetable oil... Redline has ester based engine oil... These goes for over RM200 for 4 Quarts or 4 Litre equivalent.
