Actually i don't know about oil. So what is the most suitable oil for inspira?
what is the different between s800 , s1k, s3k? And how to know after change how long can go for?
the oil cant always change?? I think my car now always different~
I also sleepy now~ I everyday work also feel sleepy.

s800-semi synthethic 10w40
s1000-??
s3000-full syhthetic 10w40?
Check Petronas website lar.
Anyway, i think xW40 should be ok...anything more than 40 is a bit too thick and sucks even more fuel. Unless you rev kaw-kaw everyday and redline, i don't think you'll need xw/50.
Say, is it ok if we use xw30 for our engines? Would it be too thin for 2.0cc engine? (But maybe saves more fuel?).
