As gas prices rise, more people are turning to products which claim to inprove mpg, such as many fuel additives. Before dumping even more money into a bottle of fuel additive, consider if the product is really necessary, or even helpful for obtaining better gas mileage.

Additives are believed to promote better gas mileage as well as give the engine life a boost. This may hold true for some additives and in certain cases. Although, all these additives do is clean the parts like fuel injectors and fuel lines, removing deposits that block the unrestricted flow of fuel. Hence, these additives may be rendered useless by a regular maintenance regime involving dismantling and cleaning of fuel injectors.

Moreover, in the developed nations gasoline already has additives in it. The regular gasoline has less additives than the premium one. Despite the higher octane rating, premium gasoline does not improve efficiency of most passenger vehicles. They only work in older engines that has "pinging" problems or a few specialized engines like the engine of a boat.

If regular vehicular maintenance has been an oversight for you, you might want to try using a fuel additive, which is designed to target the neglected components, such as clogged fuel injectors. Using a fuel additive can be a temporary solution for clearing water from the fuel tank or fuel line. This can be especially true for vehicles that have an unknown maintenance history.

With these specific exceptions, fuel additives are usually not needed. Most gasoline already contains similar additives, and more of these additives will not help your engine get better gas mileage. In addition, high levels of additives will cost you money and damage the environment. If you are not sure whether you should use a fuel additive or not, consult your local mechanic and get his opinion.

Read all instructions very carefully before you use a fuel additive. Additives differ in the way they are supposed to be used and if you don't add one correctly it may not help you at all. Some additives sink when mixed with gasoline. Others may float. Make sure you know what you are doing before you use one.
