[QUOTE="1995COBRA-R, post: 3487434, member: 9515"] My engine builder recommended 20W50 (any good brand; mineral) for one weekend and then a switch to synthetic 15W50 Mobil 1 (early pushrod 302). After 29 race weekends (and a busted head gasket), I pulled the engine and he reported absolutely no bearing wear. He also taught me to cut open the oil filters after each oil change to watch for metal debris. I found some in the oil filter during Sebring and stuck it in the trailer. I'm glad I checked as after the engine was pulled; he found a sleeve had moved and destroyed the rings. The metal was ring material. I'm sure the engine would have blown if I had kept running it that weekend. I am sold on Mobil 1 but wonder if all aren't mostly the same? :shrug: I use syn. 10W30 Mobil 1 for my 94/95 cars and syn. 0W20 Mobil 1 for my mod motor truck. I buy several cases when it is on sale. I use Ford filters. [/QUOTE]
