A friend of mine has a 90 Chevy truck,he claims the 350 engine uses of quart of oil every 50-75 miles, gonna have to pull it. When he drove off I didn't see a cloud ,but just that puff of oil smoke typical of high mileage smallblocks, no big oil drops left behind either.I figured a quart every 50 miles is a real smoker, whats up?
