[urq] Burning huge amounts of oil

Thanks for the info Frank. Good point. Still, if that amount of oil is
burned, why can't I see any of it back at the exaust? One could say that
such amounts of oil litterally 'leak' out the exhaust in liquid form rather
When idle there is no smoke (only if I rev real hard) and when driving on
freeways (very aggresive) I can't see any smoke either. Strange indeed...
Someone said I might not *notice* any smoke and wet plugs because the oil is
of such good quality (Castrol RS 10W60). Does this make sense? We are
talking 1 liter per 500km here....
