Perhaps I should just give Simon (Oilman) a ring but I wanted some opinions first.
I asked my local (German) Honda dealer about booking in for the first service - anyway I wanted a quote with me supplying my own oil to which they replied that make sure it's not fully synth.
They had a bulletin apparantly from Honda a few months ago stating that in all high power high revving petrol engines (eg K20A, F20, B18 etc) fully synth is far too thin and does not go well with high revs.
Further to this they said that they WILL NOT fill my car with fully synth, and if they found out I put some in then they will void my warranty?
Has something happened to a VTEC engine with fully synth in it some time ago?
