One of the problems with running low quality oil over a long period of time is that the more you run this kind of oil, the more likely you are to end up with a lot of gunk getting caught up in the inner workings of the engine. Low quality oil leaves more deposits and has more things in it that can clog up the engine. This can ruin the performance of your motor.
Luckily, there is an easy way to avoid forming these deposits and that is to use high quality oil each time you add oil to your boat. If you have already been using low quality oil for a while, it is a good idea to clean out the gunk in the engine before you start using better quality oil. There are several additives that can be used for this part of the process.
To make sure that you are able to clean out your engine, I recommend using Ringfree plus additive to get all of the bad things out of your engine. When you finish running this through the motor, you’ll be able to go on to use better quality oil. If you get to it fast enough, you can prevent performance problems before they start.
