Eli tuolla testillä ei ole juurikaan mitään tekemistä reaalimaailman kanssa, koska siinä ei käytetty kokonaista moottoria. Näinollen esim. mitään palamistuotteita ei öljyn sekaan kerry."This is a gross miss-representation of what SAE Technical
> Paper 2003-01-3119 determined. The title of the paper is -
> "Antiwear Performance of Low Phosphorus Engine Oils on Tappet
> Inserts in Motored Sliding Valvetrain Test" The test was a
> pure wear test using externally driven valve train components.
> A complete engine was not involved. There was no dilution of

Eli ei sitten ollutkaan koko moottorin kulumisesta.
