Hello all,
I'm making the move to synthetic at my next oil change, I've done a fair bit of reading on this and am definately taking the plunge, but there seems to be a lot of confusion about exactly which ARE synthetic and which AREN'T!
I gather ester based synthetics are best (e.g. Silkolene), hydrocracked are worst (e.g. Castrol)?
In fact, I gather Castrol is actually a complete con because hydrocracked isn't really a synthetic at all?!
So, which oils ARE and which AREN'T? Is there a defintive answer, or just many shades of grey?
Cheers, Richard.
