5/40 Ester based fully synth if you care for your engine. There's a section on opie website. You're looking at least £40 a bottle

Quantum platinum available from seat (what vag recommends)

Or if you want a better oil get quantum longlife 3 (also from seat)

Everyone has an opinion on this so you wont get conclusive advice here. My tupence worth - the VW recommended oil for 1.8T engines is 5W30 fully synthetic, I have yet to read compelling enough evidence to go for anything other than that. Whatever you go for though make sure its good quality stuff, Castrol / Mobil / Millers / Quantum etc and not supermarket or Halfords specials, I think that would make a far bigger difference than going to 5w40 or 10w40 etc.

I use a halfords vw 5w30, it's just a rebranded oil as halfords dont make there own oil. Not sure what brand it would be.

Wouldn't go for 10w40 when you can buy 5w40 - just as thick at higher temps but thinner when cold for better cold start protection.

In general you're right, the branded more expensive stuff tends to be better...

If you want some reading there's plenty on Opie Oils website

Yeah I agree, they were just random ones I threw in for the sake of the argument. Thats some good reading there. I read a huge article once about multi-grade engine oil its pretty complex stuff actually and quite tricky to understand, I cant seem to find it now annoyingly. Anyway their conclusion was that unless you have a very good reason not to, just stick with what it says in the hand book.

Yeah there's quite a bit of info to get through!

Have you read the article for modded cars? Basically saying heat is increased massively compared to power increases... For that reason I'd rather use a 40 viscosity on the basis it's likely to be nearer the required viscosity at the higher temps than a 5-30 would be, and the 30 would be too thin when the engine gets hotter due to the increased power. Happy to loose an mpg or two for the extra protection it should be giving!
