Industrial fuel treatments help improve engine performance

With the high cost of fuel and the need to get every last mile of performance out of our engines, LE’s fuel conditioners are a simple solution for improving engine performance and improving fuel economy. These gasoline and diesel fuel treatments have been formulated for use in heavy-duty industrial fleet applications. Whether you operate trucks, buses, farm vehicles, construction equipment, marine engines, or even mowers and chainsaws, our fuel treatments help you maximize engine performance and save on fuel costs – making you greener in the process.


Cetane-boosted Full Torque™ keeps injectors clean

Full Torque Trucking

If you liked our old BTU+ diesel fuel treatment, you will really like our new high-performance Full Torque™ Diesel Fuel Improvers. Field-tested for several months on the ice roads of Alaska, Full Torque has proven to be a valuable asset for long-haul diesel engine operators fighting to keep their trucks on the road despite harsh environments.

Full Torque is a cetane-boosted, detergent-containing fuel additive formulation that increases power, improves fuel economy, reduces emissions, and provides smoother performance year-round in diesel engines. Full Torque’s cetane booster increases a fuel’s cetane number up to three numbers, resulting in faster ignition time, more power, easier starts and less smoke at startup. This hard-working diesel fuel conditioner is also loaded with special detergents that keep injector systems clean and working at maximum performance, as well as ingredients that protect against wear, water and corrosion. Full Torque has been formulated to work with today’s biofuels, ultra low sulfur diesel (ULSD) fuels, and renewable diesel fuels. It also works with today’s high pressure common rail systems.

Gasoline fuel treatment protects engines & helps fuel economy


L-X 2300 Pint

L-X® Heavy Duty Chemical Supplement (2300) is a combination of oils and chemicals carefully formulated for use in automobiles, trucks and other gasoline engines. It increases power through a more efficient combustion of the fuel, which in turn improves fuel economy.

L-X keeps engines clean and reduces frictional wear by combating carbon, varnish and gum deposits that prevent an engine from operating at maximum efficiency. It also protects engine parts, physically permeating the metal surfaces and adding a sacrificial layer to protect rings, plugs, pistons, valves, carburetors, and fuel injectors from heat, corrosion and acids. This uncanny ability to permeate the microscopic pores found in metal surfaces lends itself to a variety of additional uses.
