The more I think about it I got very good gas mileage using ARCO and it seemed to run cooler in the AC season. Also used it in my wife's Mustang with the same results after switching from regular oil and it ran smother and leaked a lot less. I remember she would complain that every one that checked her oil was shocked how black it was. Every one wanted to change it People get a mindset that if oil is not honey color and is black its bad. It can be disheartening to have just changed your oil and a station attendant is telling you your oil is bad and needs to be changed ASAP. Probably more of a PR problem than bad product.

The problem as I recall was not in new or clean engines. What seemed to be happening was that in older engines it seemed to very rapidly form sludge, enough to clog filters and oil pickup screens. On a personal note it cost me a girl friend when I put it in her car and killed the engine. Looking back that was actually a good move, I have a GREAT wife who not only tolerates my cars but wants me to get her 49 Dodge truck on the road. Dennis C.
