Miguel;
GM made a movie of a 1957 Chev Taxi owned by the Devonshire Hotel,
Vancouver, B.C. changing Delo 400 every week, it went one million miles,
on 4 valve grinds. No bearing changes.

I took a GM 427 gravel truck engine apart, looking for a crank that
could be turned. The engine had sat in a field for years. 400,000+
miles and the crank was as new. Delo 400 changed every week, as the
truck was used off highway. The owner had tossed the engine, "because
it was old."

I still want to know why Dick Paterson highly recommends Mobil 1. He
says it give better protection and heat transfer than any Dino oil. No
downside?
