Exhaustive directory includes listings of additives, engine modifications, kits, books, efficient engine technologies.

Problem 
While people hear rumors that methods exist to increase mileage, and they believe that this is most likely the case, the task of weeding through the many claims and scams is daunting.
Solution 
This directory is becoming a trusted source where people can come to find just what technology would be best for their particular car and ability to install and budget for installing. Once you have installed a system, feel free to come here to report your results, to either substantiate or contradict the claim, so that the absolute best technologies trickle to the top.

This site is built by you: the experienced researchers, investigators, and consumers who have knowledge to impart on this subject. Our collective wisdom is far greater than any one person who might compile a site on their own. Because you can edit this site, you can help build it into the most reliable and helpful resource on this subject.

  • how to get better gas mileage
  • Pumping the gas pedal is somewhat like flushing the toilet. Accelleration takes a lot of gas.
    • Use speed control to maintain a constant speed.
    • Do not accellerate quickly.
    • In stop&go traffic, try to avoid rapid start & rapid stop. Give yourself some buffer space between you and the car ahead to reduce the rapid start & stop cycle of the traffic.
  • Keep tires properly inflated.
  • Keep engine in good shape i.e. cleaned out with Redex periodically
  • Keep windows rolled up for better aerodynamics at high speeds.
  • Turn off the air conditioning at low speeds, and use windows.

Or perhaps you should build for yourself some awareness of the environmental significance of your action. The following paper proposes that the amount of emission each vehicle user is generating can be instantly quantified and visualized in terms of a geographical area that is large enough to absorb all the pollution.
