I would like to begin the process of gradually cleaning out my engine with Auto-Rx. The question is, what oil should I mate it with? I would like to use a cheap but good dino oil such as Chevron Surpreme, but I am leaning towards combining it with one of several fleet oils. 1) What are your recommendations for a dino oil? Since the oil will probably be changed in less than 1,000 miles, is just about anything OK to use? 2) If I choose to go with a fleet oil, would the detergent package be too robust? I would like to slowly and safely cleanse the engine internals, not flush it out all in one foul swoop. Thanks.
