I have always used pennzoil in my cars. That yellow bottle has always given my cars complete oil coverage and decreased the wear and tear on my motor. Continued fan for life!

A relative used this(not the racing version) is his Chev V8, straight 30w, when he set a drag racing class world record. He says it never let him down. That's good enough for me too!
