What do you think of the product Rislone engine treatment? It's been around for years. Have you used it?
Yes, it’s a good cleaner and additive. I know people who have used it. It’s very good on old junkers that have lots of problems and they clean them out. It’s not a miracle. A lot of times, people say "I poured oil and this oil additive in, and my car stopped burning oil. It burned a quart of oil every 50 miles and now it doesn’t burn any." That kind of story is typically nonsense. That drastic of a change will never happen just by adding additive. But Rinslone is a decent additive, especially on the older cars that are worn. It will help them last somewhat longer.
