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.

About
Overviews
Model of Efficiency - PBS/Nova has a "Car of the Future" feature addressing the question, Why haven't cars improved more in fuel efficiency over the decades? View the brief 5-part Nova video with Amory Lovins and Rocky Mountains Institutes' new hyper car presentation. (Thanks Wesleybruce)
How Many Miles to the Bushel? - The May issue of Popular Mechanics compares fuel costs for various types of fuels. Coast-to-coast drive would be $60 for coal (electricity) $110 for natural gas $213 for gasoline $231 for biodiesel $425 for E85/ethanol $619 for M85/methanol $804 for hydrogen. (NYTimes May 27, 2006)
U.S. can cut oil imports to zero by 2040 - Since vehicles use 70% of oil in the United States and 75% of fuel use is weight-related, the biggest savings would come from making cars lighter, which would reduce oil consumption and make cars safer and more reliable. "Ultralighting" vehicles using carbon composites or ultralight steels is essentially "free" with cost increases for materials offset by gains in efficiency. (Mongabay Mar. 29, 2007)
Top 4 Ways Automakers Can Meet New MPG Standards - New CAFE standards will jump to 35 mpg for all cars and SUVs by 2020, up from 27.5 mpg for cars and 22.5 mpg for trucks. Here are four keys for automakers to bolster their fuel economy: Reduce weight, use diesel engines (30% more efficient than gas), low rolling resistance tires and continuously variable transmissions. (Popular Mechanics Jun. 21, 2007)

Economical Vehicles
Directory:Fuel Efficiency Vehicles - The most economical vehicles in production today are TDI diesels and hybrid electric vehicles. Other topics include concept cars and high mileage gasoline cars.
Electric Vehicles
Directory:Electric Vehicles (Separate page) - The fuel cost for an electric car is one quarter that of a gasoline car. Lithium batteries extend the range and top speed. Choose from several new models or convert a conventional car into an electric car.

Electric Trucks
Directory:Electric Trucks - Electric trucks and utility vehicles.
Electric Scooters
Directory:Electric Scooters - There is great alternative to city commuting -- electric scooters. The cost to travel 10-20 miles is well below $0.2 as opposed to $2 on city bus (NYC). Scooters require less mass to be moved, and hence can be far more economical.
Solar Vehicles
Hybrid Vehicles
Directory:Hybrid Vehicles - Hybrid Vehicles run on a combination of propulsion systems to achieve greater fuel efficiency. Most commercially available hybrids (such as the popular Toyota Prius) are classified as HEVs (Hybrid Electric Vehicles). HEV cars typically use gasoline as the fuel, but they also have an electric motor which can propel the vehicle. Electricity is generated by recovering braking energy as well as directly by the ICE. It is stored in batteries and used by the electric motor to assist the ICE and even to propel the car by itself (primarily at low speeds where the ICE is inefficient).
Hydrogen Vehicles
Volkswagen HyMotion fuel cell vehicle - built into Volkswagen's new Tiguan crossover model, uses hydrogen to create electricity, providing power for the car's electric drive motor. It also has a lithium ion battery pack for extra electricity storage, and gets the gasoline equivalent of 42-to-62 miles per gallon. (CNet Reviews June 12, 2008)

Wind Resistance
Aerodynamic long tail improves fuel efficiency 15 percent - Ecomodder.com’s Darin Cosgrove added a tapered tailpiece to his Pontiac Firefly to improve its drag coefficient from 0.34 to 0.23 and its fuel efficiency by 15.1 percent at 90kmh (56mph) with/without measured from multiple bi-directional averaged runs at exactly 90kmh on a straight and level road, with no other traffic. (GizMag December 29, 2009)
Boat tail reduces truck fuel consumption by 7.5 percent - European tests have shown that a boat tail – a tapering protrusion mounted on the rear of a truck – leads to fuel savings and reduced emissions by dramatically reducing the drag caused by the lower-pressure effect that occurs in the wake of a vehicle. (GizMag Nov. 5, 2009)
Engineer devises ways to reduce air drag in vehicles and planes - Researchers at Washington University in St. Louis are developing an active flow control (AFC) technology that deploys actuators on the surface of vehicles to modify the air flow in a way that the overall resistance is reduced by 10-15 percent. (PhysOrg March 16th, 2009)
Yoke Arm
Fisher Yoke-Arm increases efficiency in piston engines - Yoke-Arm technology increases piston dwell during combustion for high combustion and fuel efficiencies in combination with significant power gains. All with the addition of a single component part, the yoke-arm.
Other Methods
GM's Spark-less Engine Boosts Fuel Economy By 15% - GM's homogenous charge compression ignition engine (HCCI) is able to improve fuel economy by 15 percent when combined with other advanced technologies. HCCI works by igniting the air and fuel mixture through compression instead of with a spark and saves fuel by reducing pumping losses, burning fuel faster at lower temperatures and reducing the loss of heat energy.

Electric Freight Rail
Directory:Electric Freight Rail - Electrifying railroads and transferring half of the ton-miles of trucks to rail could save 6.3% of US oil consumption. Electric railroads, well-proven in other countries, are cheaper to operate and can carry more freight because they accelerate and brake faster (and can generate electricity while braking, saving energy), and have no delays for refueling.

Butanol can be produced at an estimated cost of 85 cents per gallon, and is a direct replacement for gasoline.
Hydrogen Peroxide
Directory:Hydrogen Peroxide as Fuel - Hydrogen Peroxide (H2O2) has been used as rocket propellant, but can also be used to run automobiles. With how well it stores in liquid form, it is perhaps an under-appreciated mechanism for energy storage and fuel. Could possibly find application as a fuel for jet aircraft engines.
Hydrogen from Water
Directory:Hydrogen from Water - Hydrogen can be generated from water by `splitting' it from oxygen. The most well-known process is electrolysis, but other mechanisms exist as well, such as catalyst in the presence of heat (e.g. solar).
Biodiesel from Algae Oil
Directory:Biodiesel from Algae Oil - Advantages include rapid growth rates, a high per-acre yield, and algae biofuel contains no sulfur, is non-toxic, and is highly biodegradable. Some species of algae are ideally suited to biodiesel production due to their high oil content--in excess of 50%.

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.
