Default Re: Changed The Weight Of My Oil

Well, I knew this would create a stir. I like how my engine sounds with the change and the increased oil pressure. The engine was rebuilt and has been using synthetic since the rebuilt about 3000 miles ago. The synthetic STP is no where as heavy as the original STP, it actually pours like oil. No oil filter on my car, just a lot of oil changes. In the spring if I go to 20W-50 I will opt out of using STP and see how things sound. We grew up using STP in every car and flatheads. I worked at a car garage as a teenager, some lady pulled in off the highway said her oil light was on for the last 8-10 miles. Found oil filter had fallen off and no oil in the pan. The customer had used STP in it, we filled with oil, she drove off, engine was fine. Made me a believer in the product.
