1. High Performance Air filter

This in one of the easiest fuel efficiency and performance modifications you can do and usually takes less that 10 minutes. Standard air filters can become clogged and restrict airflow after only a few thousand miles and reduce your gas mileage and power by as much as 10%. High performance air filters have less restriction to air flow which increases fuel efficiency and horsepower. There are many on the market that do this but most have a serious flaw: they are poor air filters and allow a lot of dirt into your engine. Our AMSOIL air filters use military technology to increase air flow and provide unsurpassed filtration.

2. Fuel System Cleaners

Your engine needs clean fuel injectors, valves, and combustion chambers to produce maximum fuel economy and performance. But burning gasoline and diesel fuel leaves deposits that clog fuel injectors, fuel filters, and emission systems. In addition, combustion deposits build up on valves, pistons and ports. This results in less efficient combustion, reduced horsepower, and wasted energy. Regular cleaning or your fuel injection system and combustion chambers is a cheap, easy way to increases gas mileage and performance.

3. The Best Synthetic Motor Oil Another way that your engine wastes energy is by the friction between all of those moving metal parts in your engine that are spinning and sliding at incredible speeds. Conventional motor oils break down quickly, get thicker, and make it harder for your engine to move it's pistons, valves, cams, and gears. AMSOIL, the leader in automotive synthetic lubrication, produced the world's first API qualified synthetic motor oil in 1972. They have more experience than anyone else. AMSOIL engineers their synthetic oils to produce more power, get better gas mileage, and last longer that any other motor oil period. Many AMSOIL synthetic motor oils last up to 25,000 miles which will save you a lot of money on oil changes. For maximum performance, better gas mileage, and saving you money, this is the best synthetic motor oil you can get.

4. Correct Tire Pressure

This is one of easiest and free ways to improve gas mileage yet is often the most neglected maintenance item. Correct tire pressure is critical for good gas mileage, vehicle handling, and safety. Keeping your tires properly inflated will improve your gas mileage by reducing rolling resistance. But what is the right pressure to use and what is the only time you should check it?

5. High Performance Spark Plugs

Power and efficiency in gasoline engines depends on consistently strong sparks. The intense heat of combustion degrades the performance of standard spark plugs causing reduced power and fuel economy. They will still spark after 10,000 miles, but it will be less intense and cause incomplete fuel combustion which wastes energy.

NGK is the world leader in spark plugs and spark plug wires and makes some of the highest performance ones available, covering nearly every type of vehicle. NGK has been producing world class products since 1936 and has dominated the world market.

6. Fuel Efficient Driving

This step only requires a little thought and your right foot to save you a lot of money. And it is free. How you drive has a huge effect on your gas mileage and there are some very simple ways to make big improvements.

7-8. Reducing Drive Train Energy Losses

Your transmission and differentials are another place where energy is wasted through heat created by friction. Iron and steel gears rubbing together under high loads consumes power and fuel. By installing the best low friction synthetic oils you can cut these losses significantly and dramatically reduce wear at the same time. These oils also last longer -up to 100,000 miles in cars and trucks. This means lower maintenance costs. The sections on Synthetic ATF, Manual Transmission Oil and Synthetic Gear Oil show you what works best.

9. Auto Repair and Tune Up You probably know this one but the miles go by so quickly when you are busy. To keep your vehicle fuel efficient, safe, and running at its best, you need to give it regular maintenance. Many engine parts loose efficiency over time as they wear and get dirty. In addition, modern engines have a lot of complex emission controls and sensors that can go bad and reduce your gas mileage and performance. If your check engine light is on, then you need to take it in. No one enjoys paying for auto repairs, but you will pay for it at the gas station if you don't get it repaired. So take care of any problems and get your brakes and tires checked while its there. Good brakes and tires are very important safety items that can help you avoid an accident. 10. Free Ways to Improve Gas Mileage Here are 7 more free and easy ways to increase your gas mileage and save money. You will be surprised at how simple some of these are. Your Actual Performance and Gas Mileage The key to achieving maximum performance and gas mileage is to add up many small improvements without neglecting any major ones. How Much Can You Improve Performance and Gas Mileage? Most of these steps can increase your gas mileage and/or horsepower by two to five percent, and some up to 10% (there is no gas pill, magnet, or magic device that will produce large mileage increases). You may not notice a single small increase, but you will feel it when many small improvements are added together. Example: 3% + 2% + 4% +3% + 5% + 2% + 3% + 4% = 26%! And that included only eight of the ten steps as your car may not need them all. Good for the Environment This gas saving program also helps the environment. It will reduce your vehicle's exhaust emissions and pollution which can help fight global warming. Please remember when checking your gas mileage that it can vary substantially from one tank to the next. Your gas mileage is affected by traffic flow, your driving habits, your driving speed, the mechanical conditional of your vehicle, the load you are carrying, tire pressures, air temperature, altitude, the weather, and the quality of the fuel in your tank. To obtain good MPG values check your gas mileage by averaging the results from three to five tanks of gas. Your mileage results will vary for each vehicle and driver combination (a lead footed driver can quickly reduce the number or miles that you will get from a tank of gas).
