Poly, I have a Etec, but I have the special desire,,not to fook up the engine !!
Simple really. so any TCW3 derivative is ok ?
I'm more of a simple tech person. Presumably you have the engine set for TCW3 already. There are some super fancy (i.e. expensive) etec oils around - but if your engine is set for them you shouldn't use bog standard TCW3 - as I understand it.
