You'd think but I pulled them 10k ago an they were in fairly good condition not much built up on the electrodes. 2 nct's and low emissions it used to bother me but now I just keep a few liters handy.after all the car is only worth the price of a rebuild on the engine, so for now as long as it keeps goin and passing nct's a few liters of oil is no big sacrifice :-)Originally Posted by owly
