One of my friends isn’t exactly known for taking great care of his boat. Since he doesn’t have very much money, a lot of his money is actually going into his boat. However, since he doesn’t really have much money, he tends to try to use cheap oil and cheaper gasoline when he can. This is fine in the short term, but could cause damage later.
In order to keep his engine running well, even when he doesn’t spend enough on quality oil, he uses ringfree plus. By adding this to his engine, he can minimize the deposits that are created by the low quality oil and gasoline that he is using. With any luck, this will keep the engine running for far longer than it would normally.
