My uncle has been running his boat engine for several years now and has started to worry that the way that the engine is running could be affected by the build up from oil and gasoline in the system. He has started to become more concerned because one of his friends recently had to take apart his boat engine. He discovered a lot of nasty build up inside the motor.
In order to keep the boat running at its best he decided to try a oil additive that would help clean out the engine. He ran some ringfree plus through the motor to get rid of any carbon build up that might be inside of it. Now that he has been out on his boat a couple of times running with this additive he feels a lot better about his engine and isn’t as worried.
