id ask about the 30 thing mate, to be sure, from a real expert on tuned ones.
maybe start a new thread on here. ive certainly never known any engine to only be able to handle piss thin 30 oil!
sounds proper madness to me, 40 is more like it for a hard driven car.

and bank, id jus meant "id be sure"

and no prob about the help, your cars wicked, so i wanna help fix what im thinking is a fairly minor issue thats causing a whole shitload of smoke, lol.
ive had a lot of experience of hard tuned cars smoking like cunts, and how to stop it, so hopefully i can do some good, lol
