With the cost of fuel on the rise, thrifty drivers look to improve mpg with the use of fuel additives. But before using the all important dollars you earn on a product that supposedly helps you, make sure that this expenditure will actually help you get better gas mileage.
People hope the additive will provide better gas mileage, or extend the operational life of the engine. Some additives in some cases can indeed do one or both. However, these additives work by cleaning parts, such as fuel injectors and fuel lines, of excess deposited materials which are inhibiting the smooth flow of fuel. Proper maintenance of the vehicle, including periodically taking apart and cleaning the fuel injectors, renders unnecessary the addition of a cleaning agent to the fuel.
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 you have neglected the care of your vehicles fuel injectors or other parts of the engine, then you may try to use a fuel additive to make up for it. You may need to use an absorbent fuel additive temporarily if there is water in the fuel lines or the gas tank. If you do not know how well maintained a vehicle has been, a fuel additive may help it perform better for a little while.
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 do not 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.
As gas prices rise, more people are turning to products that claim to improve 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. These additives work by cleaning parts, such as fuel injectors and fuel lines, of excess deposited materials that are inhibiting the smooth flow of fuel. Moreover, in the developed nations gasoline already has additives in it. The regular gasoline has fewer additives than the premium one. You need to carefully follow instructions if and when you decide to use such additives.
