Prevents Fuel From Gelling

Howes Diesel Treat is the nation’s most trusted anti-gel. Its special formula has been tested and proven time and again to prevent gelling in even the coldest weather. Owners of all types of diesel vehicles and equipment rely on the Howes family’s guaranteed product to keep them going all winter long.


Adds Lubricity

Diesel Treat helps protect against today’s Ultra Low Sulfur Diesel (ULSD) fuels by providing added lubricity to injectors, pumps, and upper cylinders. In doing so, it extends the life and increases the performance of diesel engines of all types.


Prevents Deposits

More than just an anti-gel, Diesel Treat also contains a specialized detergent package to help prevent fuel injector deposits. Carbon deposits on diesel injector systems can cause loss of engine power and other issues. Preventing these helps to improve performance and fuel economy, saving you money.


Removes Water

Water is abrasive to your system and can lead to fuel filter icing. Many products emulsify or mix water into the fuel, often using harmful alcohols or solvents that can do additional damage to your engine. Petroleum-based Diesel Treat demulsifies water, safely pushing it out of the fuel using no alcohol or harmful solvents.
