Have a 1988 Chevy S10 with 88,000 miles. Minor oil leaks and smokes on start up but think that is due to head gasket leak. Added Auto RX yesterday. Can see grime in oil cap access to engine. Will update post with results.
I'm about 200 miles into the treatment and the oil pressure gauge that has always jumped all over the place since I've own the truck has settled down and started reading oil pressure like it was designed to do. Something is surely at work in the engine after the Auto-rx treatment.
