Carbon build up can be an engines worst nightmare. It really starts to become a problem when fuel is not completely burned and leaves a carbon residue in the engine cylinders. This is really only an issue with older cars that have been driven more and have higher miles on them. It all really depends on the car and how you drive it sometimes. With higher performance cars and sports cars a good way to prevent this buildup is to drive at full throttle up to 80 miles per hour or so, of coarse you have to be careful when doing this and do it at a safe time and place. If you do this at least few times a week it will force all of that bad residue out through your exhaust system. So in a sense sports car and performance car owners have a justifiable reason not to baby their vehicles. However, if you’ve already got a significant amount of carbon built up in your motor this will not get all of it out. There are many products you can buy that will burn off all the extra carbon. Some of these products you can put directly into the gas tank and they will work quite well. In my experience though, using a product called Seafoam fed directly into the cylinders via the vacuum tube works best. This is slightly more difficult to do if you don’t have a general knowledge of automobiles. Despite what most people think it is also perfectly safe for you car. Don’t be alarmed when you see plumes of white smoke coming from your exhaust, this just means that the Seafoam is working by burning off all that extra junk that you DONT want in there. Seafoam is a multi purpose additive, it can be added strait into the gas tank, the crank case or fed into the cylinders via a vacuum tube.
