Everything Your Engine Needs
In One Product

All-In-One Solution

XFT is a comprehensive fuel treatment. Other products may have one or two of our components, but none have all of them. It would take many products mixed together to even come close to giving you the same benefits as using XFT.

1. Prolongs Engine Life and Reduces Wear
XFT uses a combination of ingredients that work together to keep your engine clean and running smoother. The result is that the moving parts of the engine and fuel system have less friction, run longer, work better, and cost much less to maintain.

2. Increases Fuel Economy
Reduces fuel consumption, resulting in increased miles per gallon.

3. Reduces Harmful Emissions and Pollutants
Reducing harmful pollutants from the exhaust pipe results in a cleaner environment.

4. Improves Vehicle Performance & Horsepower
Burns more of the available British Thermal Units (BTUs) in the fuel, resulting in better performance.

Good for your engine;
Good for the planet

We only have one planet, and we all need to do our part to keep it healthy.

You don’t have to stop using fuel to reduce emissions—you just have to use it smarter. Enter, XFT. XFT creates a more efficient fuel burn, so less fuel is wasted. By using XFT, dangerous by-products like particulates, carbon monoxide, and hydrocarbons do not form, and emissions are significantly reduced.

It’s simple to lower your carbon footprint with XFT. Simply pour it into your tank, and XFT does the rest.

Superfood for your engine

The unique XFT formula contains multiple ingredients, each designed for a specific purpose. It’s like superfood for your engine.

1. Organometallic Compound
A catalyst that ignites fuel at a lower temperature, providing a longer, more complete burn of the fuel. This causes the fuel to be used more efficiently, providing improved fuel economy and less wasted fuel out through the exhaust, which reduces emissions. The organometallic compound burns more of the available BTUs of the fuel.
2. Lubricants
Reduces friction from pistons, pumps, and injectors, which would ultimately wear down the engine, therefore prolonging the engine’s working life.
3. Detergents
Cleans and maintains injectors, as well as the rest of the fuel system, so the engine works as efficiently as possible.
4. Polymerization Retardants
Reduces solids that form in the fuel tank and keep the engine clean, prolonging the life of all engine parts.
5. Rust & Corrosion Inhibitors
Removes and prevents rust in the fuel system, keeping it running efficiently.
6. Demulsifiers
Helps separate water from fuel. A single drop of water can cause an injector to fail and damage the entire engine.
7. Fuel Stabilizer
Stabilizes fuel to keep it from breaking down or deteriorating, and gives fuel a longer shelf life.

How to use XFT

You don’t have to know the details of the science behind XFT’s unique formula;
you only need to know how to use it.

XFT Foil Pack - Pour into your tank


Pour XFT into your near empty tank.

Gas Pump - Fill up your tank


Fill up your tank with gasoline.

Car - Enjoy the benefits


Enjoy the benefits of a comprehensive fuel treatment.

DOUBLE DOSE YOUR FIRST THREE TIMES USING XFT TO REALLY CLEAN OUT YOUR ENGINE AND SEE QUICKER RESULTS (1/2 oz. for up to 20 gallons of fuel/20 ml up to 75 litres of fuel).
Subsequent treatments use 1/4 oz. for up to 20 gallons of fuel/10 ml up to 75 litres of fuel.

It’s best to add XFT prior to dispensing fuel, however, XFT is safe to add to your vehicle at any time. Simply estimate the amount of fuel in your tank and treat accordingly.

See product label for further dosage information.


XFT is super-concentrated, so you don’t need a lot.
Just ¼ oz (10 ml) of XFT™ treats a 20-gallon (75-litre) tank.

XFT - Did You Know?

  • Contains no alcohol
  • Can use lower octane fuel and engines will perform like using higher octane fuel
  • No warranty issues (does not change specs of the fuel)
  • Provides more horsepower
  • Safe for all 2-cycle and 4-cycle engines (lawnmowers, snow blowers, generators, etc.)
  • Can be used in all types of fuels (gasoline, diesel, ethanol, and bio-diesel)
  • EPA registered
  • Keeps sensors cleaner from carbon buildup
  • Keeps fuel from separating during storage

Don't Worry!

You don’t need to be nervous to use XFT. In fact, many owner’s manuals actually direct you to use a fuel additive to combat the negative side effects of things like ethanol and poor fuel quality and to make your engine last longer. XFT won’t affect your warranty either. (XFT doesn’t change the specs of fuel, so it can’t affect the warranties.)

Frequently Asked Questions

You should double-dose your first 2-3 tanks and then use one dose per fill-up after that. For generators, we recommend 3-5 double doses. Follow the dosage guidelines on your XFT package.
The organometallic compound utilized in XFT is referred to as a sandwich compound, which is generally classified as a burn rate modifier for all types of fuels. The active ingredient compound reduces combustion ignition delay and helps to remove existing carbon formulation on internal combustion components, resulting in improved engine life, improved fuel economy and reduction of emissions.
Between 1:5,000 to 1:10,000 (1 part XFT to 5,000 or 10,000 parts fuel), depending on the type of fuel used. Heavy fuels will have a lower treat ratio compared to No. 2 diesel, ethanol, or 83-89 octane fuels.
XFT does not change the specs of fuel (see ASTM D975). If XFT does not change fuel specs, it cannot affect the warranties. Syntek also maintains insurance for any claims that may happen by using the additive. In over 25 years of use there has never been a claim against Syntek's insurance.
XFT does help with lubrication. In newer, lower sulfur fuels there is a lack of lubricity agent. This means injectors are not getting enough lubrication. XFT has a high level of lubricity, thus helping the engine to run longer and more efficiently, therefore lowering maintenance issues.
XFT was specifically tested to ensure complete compliance with the applicable standards associations' performance criteria. This includes the American Society of Technology and Materials (ASTM). Furthermore, the product has been evaluated by, and is registered with, the Environmental Protection Agency (EPA).
XFT was formulated to reduce solids, water, rust, and corrosion. With its detergents and lubricity agents it will help clean and protect fuel tanks, fuel lines, pumps, filters, and injectors. XFT also benefits engine valves, pistons, rings, and cylinders eliminating carbon build-up, and significantly increasing engine life.
There are many factors that contribute to automobile fuel economy. Some people may need to use XFT over a longer period of time depending on engine type, age of vehicle, maintenance, etc. Increases in fuel economy is just one of the benefits of XFT. Numerous tests prove that it is working, so you may see the benefits in other ways, like reduced emissions or improved performance. XFT is a scientific based product that works every time.
