I use synthetic, I change every 9k as advised by the handbook (I think our
conditions are far less dusty over here in the UK). I agree with what you
say about them in the last paragraph, but my oil has ester content which
is
*supposed* to reduce engine wear during a cold startup. Apparantly this
is
when most wear occurs?
