How to Improve a Vehicle’s Fuel Efficiency Without Causing Damage
There are many fuel saving devices available nowadays, and some of them not only don’t work, but can also cause damage to your car.
The Environmental Protection Agency did tests on over 100 fuel saving devices and found that most did not improve efficiency at all and the rest didn’t improve it by that much.
The fuel saving devices available come under many different classifications. These include, driving habit modifiers, fuel line devices, mixture enhancers, ignition devices, engine modification devices, fuel and oil additives, vapour bleed devices and air-bleed devices.
The EPA’s test were designed to evaluate whether the devices had any significant impact on a vehicle fuel economy. What they could not test for was whether the devices would have any adverse effects on a cars performance over time.
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, because their carburetors are pre-set for a maximum amount of air to be burned with the fuel. “Air-bleed” devices will not work at all on many cars manufactured after 1982, because these cars have “feedback” carburetors that automatically adjust the air-and-fuel mixture rendering the device useless.
There are too many factors that affect fuel consumption such as driver’s habits, condition of the vehicle. Because of this it is hard to believe the claims many of these product manufacturers make.
In one testimonial, a consumer gave high praise to a fuel saving device. What they failed to mention was that the car had also had a service at the time the device was put in.
There are also cases of manufactruer’s claim that their device is approved the a government body. This is never true. No government body would endorse one of these devices. At best it would have been tested by the EPA and then they should be able to show the official test results.
If you have already purchased a gas-saving product and you are not satisfied, contact the manufacturer and ask for a refund. An honest company offers a money-back guarantee. If you are not satisfied with the company’s response, contact your local or state consumer protection agency or the Better Business Bureau.
Regular maintenance and servicing is one of the best way to ensure that your vehicle is running at it’s maximum fuel efficeincy. You can find out service intervals by looking in the vehicle manual.
Below are my three tips to improving a vehicles fuel efficiency:
Getting a tune-up.
Make sure your tires are inflated to the correct pressures.
Removing any excess weight from the car’s trunk.
