At a recent technical presentation by a respected representative of a piston ring supplier, things got a little out of hand when it was suggested that half of all independent aftermarket machine shops may be either out of date and ill-equipped or misinformed as far as cylinder finish is concerned. The reason? Because the OEMs are looking for oil consumption rates of less than one quart per 15,500 miles.
Clearly, the people in the audience must have either been asleep or born yesterday because they just nodded when this totally ludicrous statement was made!
Someone needs to do the math for heaven
