What kind of engine oil do you use?

[gmonkey]

Penrite yes
Liquimoly, no cos not many places stock it, were looking at oils that youd be almost garunteed to find anywhere in Aus.
Motul wasnt tested by us either.

It to do with the "Class" of oil. Redline and Royal Purple are class 5 oils, best available atm, Mobil Syn is class 4, all the other off the shelfs are class 3 or lower.

ahh yeh.. class 4/5 is good yeh but i wouldn't be putting it in a car pre say 1995ish... for a modern engine theyre great but engine thats seen a few years they can be bad news
