Here comes trouble Posted March 7, 2008 Share Posted March 7, 2008 You do not live on the equator or at the Arctic or competing in the Indy 500. My belief is that multi-weight oil wears out fast due to the additives. For my money and if a engine is any good, I pour in Chevron Dello 400 30 weight. I just installed a good compression 2400 cc straight six in an old 1983 Maxima. Poured in a gallon of diesel to the old black as hell oil and ran the motor (idle) for awhile and then drained it out...........new filter and 30 wt Dello 400. Had to double check the dip stick because the oil was so clean. I have been doing this routine for 30 years on old beaters with great results. Dello 400 is what all those truckers use.

TrumpetRhapsody Posted March 7, 2008 Share Posted March 7, 2008 Synthetic is a no-no for high mileage engines. The detergent will cause the years of gunk to break loose and clog stuff up. Quote Link to comment Share on other sites More sharing options...
