Never heard of this guy or his organization - but why is BiTOG hosting his screed paper?

very few engines go past the Severe Service recomendation of 15K without the oil being close to depleted in the last decade.

That's part of it. I actually recommend it for PC reasons as well - to keep the snipers at bay. Bottom line? The average Joe simply does not drive 25K miles in one year - so claiming that really gained nothing.(end quote)
I've seen a few cases of 25K. But it took 14-15 months. That's a long time in the old crankcase. Amsoil does not recommend this. OTOH 12-15K in one year is very doable - come take a look at my car.
