Many exciting technologies exist today for increasing the fuel efficiency of internal combustion engines. However, in order to get the gains from these technologies, the electronics of modern vehicles must be confronted and handled. We are a specialty site that does just that. We have studied the effect of fuel saving technologies on your vehicle's sensors and developed products to correct for these effects. By doing this, all of the mileage gains available from the fuel saving technology can be achieved.

In a nutshell, the problem we are trying to solve is a simple one. Any technology that is increasing the efficiency of combustion of your petroleum based fuel, will cause additional oxygen to appear in the exhaust. This additional oxygen is sensed by your oxygen sensors, and this information is forwarded to the vehicle's computer. The computer then thinks that the air/fuel mix is too lean, and then richens the mix incorrectly.

The solution is then equally simple. We just need to compensate for this factor of the additional oxygen in order to unlock all of the latent gains your particular fuel saving device has to offer. This is where the EFIE comes in. EFIE stands for Electronic Fuel Injection Enhancer. The purpose of this device is to make these needed compensations. For more information on EFIE technology, please see our Documents Page.

All devices sold on this site are given tech support. You may visit our forums at www.fuel-saver.org, where you will often find the answer to your questions instantly by searching our existing threads. If that fails to help you, you can always email support@fuelsaver-mpg.com. Finally, if you still cannot get your question answered to your satisfaction, you call us. Please see our contact us page.

We now offer a service in which you can get the information you need about your oxygen sensors. Just fill out the Sensor Request Form, and submit it. We will get back to you with the number and type of oxygen sensors you have.
