Petronas oil

[Defcon5]

Is Petronas oil any good?

It's on offer at less than £20 for 4l of VAG507/ll04 5w30, which seems a bargain

It's supposed to provide very good engine protection - especially against Dementors.

If that's not a typo it's gone way over my head

Sorry, never read them!

Anyone have an opinion on the original question

I couldn't bring myself to buy Tesco branded oil.

I appreciate you are rather knowledgeable in this field pumaracing, but I couldn't live with myself!

That's for the Ford Zetec engines isn't it? I need something LL04 and VAG507 approved

[Defcon5]

If it has VAG 507 approval it must be pretty good though - its quite strict isn't it?

Engine failure after half a lap on new oil though? Far more likely to be an issue that was already present.
