High-Performance Auto Care Fuel Enhancer
One Bottle, Eight Uses
Each 8-ounce bottle delivers up to eight treatments — just 1 ounce per tank. Shelf-stable for up to three years.
Fast Results
A noticeable difference in vehicle performance should be experienced after a few miles.
Advanced Formula
Unlike Autoworks, most fuel treatments either boost octane or clean just one part of the fuel system, resulting in a less than 1% improvement in gas mileage.
Autoworks Fuel Enhancer helps improve fuel efficiency and provides additional benefits, including helping keep the fuel system clean, supporting longer engine life, improving performance and helping reduce emissions and overall oil consumption.
Make Your Fuel Go Farther
With gas prices seemingly always on the rise, it’s time to give your car — and your wallet — a break. The market is flooded with so-called gas-saving gadgets and treatments, from fuel injector cleaners to octane boosters, but most deliver only minimal results and can even be harmful to the environment. Autoworks improves your car’s power and performance, alleviates cold start issues, shields your fuel system from harmful sulfur deposits, keeps gas gauge sensors working flawlessly and helps eliminate deposit-related engine knocking and pinging.
Put Money Back in Your Pocket
Upgrade your fuel treatment routine and unleash your engine’s true potential with Autoworks. It’s more than just another fuel injector cleaner or octane booster — it’s a comprehensive solution for your entire fuel system. With every use, Autoworks Fuel Enhancer helps clean fuel injectors, carburetors, intake valves and ports, and even helps remove stubborn sulfur deposits from gas gauge sensors. Experience improved gas mileage, reduced emissions and enhanced engine life.

Frequently Asked Questions
What are the directions for use?
Add 1 fluid ounce, or 1 grade mark, for every 17 gallons of fuel to the fuel tank. For best results, Autoworks Fuel Enhancer should be used with every fill-up. This will help increase power, reduce smoke and emissions and keep your engine cleaner. A clean engine runs more efficiently and economically.
Are there any additional benefits of using Autoworks Fuel Enhancer?
Yes. Autoworks Fuel Enhancer boosts performance, helps relieve cold-start problems, helps protect against sulfur deposits in fuel systems, helps protect gas gauge sensors from malfunctioning and helps reduce deposit-related engine knocking and pinging.
Will Autoworks Fuel Enhancer still work if I fill my tank before it is completely empty or if I do not fill it completely full?
Yes. Your tank doesn’t need to be completely full. However, the ideal ratio is one fluid ounce of Autoworks Fuel Enhancer for every 17 gallons of fuel. The ratio does not have to be exact; it will safely blend in any amount of gasoline or diesel fuel. While adding more than the recommended amount of Enhancer will not cause any harm, it will not increase product effectiveness and would be wasteful.
What does being registered with the EPA mean?
Environmental Protection Agency (EPA) registration means that the EPA knows the product and its chemical components and how it is put together. It does not mean that the EPA endorses the product. It only means that it is registered and is known to the EPA by a registration number assigned to Autoworks Fuel Enhancer.
Is Autoworks Fuel Enhancer safe and compatible for use in various vehicles, engine types and fuel systems, including cars, motorcycles, small gas-powered equipment, catalytic converters and various fuels?
Yes, Autoworks Fuel Enhancer is designed to be compatible with common combustible engines, including cars, motorcycles and smaller gas-powered equipment such as chainsaws, lawnmowers, generators and more. It is tested to be safe for automotive components, including catalytic converters and oxygen sensors. For smaller fuel tanks, only a very small amount should be used per tank. Autoworks Fuel Enhancer has been tested for use in gasoline and diesel fuels but is primarily intended for all combustible engines; for other fuel types such as biodiesel, ethanol, fuel oils or kerosene, it is recommended to verify compatibility before use. Autoworks Fuel Enhancer is designed to work with any petroleum-based internal combustion process. Because Autoworks Fuel Enhancer is a hydrocarbon-based product, it is designed to be compatible with gasoline and diesel fuels.
How does using Autoworks Fuel Enhancer help reduce vehicle emissions?
An independent laboratory test demonstrated a reduction in the amount of hydrocarbon and carbon monoxide emissions under the test conditions.

Skeptical, but NOT ANYMORE! Wow!
5 out of 5 star rating.
This product lasts my Expedition for eight full tanks. I have a 24 gallon tank. We put 1 ounce (1/8 of the bottle) in every fillup. My 13.9-14.1 mpg has gone up to 16.1-16.3 around town! When we did the math, correct me if I'm wrong, we're saving about three gallons of gas per fillup. Which comes to about $10. So this bottle can be used 8 times, which would save us $80 in gas! These are approximates, but saving $55 on gas is a win-win to us! Buy this stuff!
