FAQ's

XFO™ does not change the specs of fuel (see ASTM D975). If XFO™ does not change fuel specs, it cannot affect the warranties. The Magnuson-Moss Warranty act is also applicable. The producer of XFO™ also maintains a $1M insurance policy from a major underwriter for any claims that may happen by using the additive.

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 XFO™ package.

The organometallic compound utilized in XFO™ 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.

  1. 10,000 (1-part XFO™ to 10,000 parts fuel), depending on the type of fuel used. Heavy fuels will have a lower treatment ratio compared to No.
  2. Diesel, ethanol, or 83-89 octane fuels.

XFO™ does help with lubrication. In newer, lower sulfur fuels, there is a lack of lubricity agents. This means injectors are not getting enough lubrication. XFO™ has a high level of lubricity, thus helping the engine to run longer and more efficiently, therefore lowering maintenance issues.

XFO™ was specifically tested to ensure complete compliance with the applicable standards and associations’ performance criteria. This includes the American Society of Technology and Materials (ASTM).

XFO™ 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. XFO™ also benefits engine valves, pistons, rings, and cylinders by eliminating carbon buildup and significantly increasing engine life.

There are many factors that contribute to automobile fuel economy. Some people may need to use XFO™ over a longer period of time, depending on engine type, age of the vehicle, and maintenance. Increases in fuel economy are just one of the benefits of XFO™. XFO™ is a scientific based product that works every time.
