Preventing your engine from too much carbon build-up by using an additive such as a carbon guard is an easy way to avoid having to repair and replace parts later. There is no way to completely prevent carbon from forming on the internal parts of an engine; a little build-up is perfectly normal. However, if too much carbon is allowed to form in an engine, performance could decrease rapidly, and lead to decreased engine life.

Additives like Carbon Guard, which is manufactured by Johnson/Evinrude, is one solution to carbon build up. Carbon Guard can prevent carbon from forming, and maybe even remove some of the existing build-up inside an engine. One oz. of additive can treat as much as 8 gallons of gasoline, making it a worthwhile investment for any boater or motor sport enthusiast.

Preventative Maintenance with Carbon Guard

Proper care of your engine during the boating season can reduce hassles, costs, and repairs during the off-season. Depending on your engine, it may be a good idea to add a product like Carbon Guard to every few tankfulls of gas. Reducing carbon build-up through regular use means less time spent de-carbonizing your engine later. Some people recommend de-carbonizing after every 75 to 100 hours of use if you regularly use an anti-carbon product, but after every 50 hours or so if you don't use an anti-carbonizing agent.

Other fuel treatments to consider during the off-season are fogging oils and fuel conditioners. During periods of rest, condensation can corrode engine parts, and leftover gasoline can turn to varnish that coats engine parts and reduces overall performance. Adding fogging oil can prevent rust and corrosion from condensation. Adding a stabilizer or fuel conditioner (such as 2 plus 4 fuel conditioner) can reduce the build-up of gum and varnish.
