don't kid yourself. I test oil at work, as long as it's still got anti-oxidants, the oil is good.

I'll be doing a write up soon when I get some more recip engine testing sample tubes in. I want to find out how good this castrol edge 5w30 is after 10k kms. Not sure where you live, but the company who supplies our equipment, have an office and lab in Sydney and Perth.
