Improve Gas Mileage Without Damaging Your Car by: Marilyn Pokorney Many of the gas saving devices being advertised do not work and can actually damage your vehicle. After evaluating and testing more than 100 alleged gas- saving devices, the Environmental Protection Agency has found only a few that improve mileage and none that do so significantly. The gas-saving products on the market seem to fall into clearly defined categories. These include, but are not limited to: air-bleed devices, vapor-bleed devices, liquid injection devices, ignition devices, fuel line devices, mixture enhancers, internal engine modification devices, fuels and fuel additives, oils and oil additives, and driving habit modifiers. The EPA evaluates or tests products to determine whether their use will result in any measurable improvement to fuel economy. However, the EPA cannot say what effect gas-saving products will have on a vehicle over a long period of time. It is possible that some products may harm the car or adversely affect its performance. For example, if an 'air bleed' device actually adds significant amounts of air to the air-and-fuel mixture, it may cause an engine to misfire, a condition which greatly increases the potential engine damage or mechanical failure. This is especially likely to happen on cars manufactured between 1974 and '1982
