Features and Benefits
Prevents Diesel Fuel From Gelling
Howes Diesel Treat’s special formula has proven time and again to prevent gelling in even the coldest weather. Owners of all types of diesel vehicles and equipment rely on Howes Diesel Treat to see them safely through the harsh temperatures of winter.
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
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.
Why Use Howes Diesel Treat?
Diesel fuel, especially biodiesel, has a high likelihood of gelling when exposed to freezing temperatures.
Gelling is the result of diesel fuel thickening up in freezing temperatures and can block filters, lines, and fuel rails. At around 34°F, you can start to see the process of gelling; fuel in the tank starts to thicken, form deposits, and get cloudy. By 15°F or lower, untreated diesel fuel may fully gel, resulting in smoke, hard starts, the loss of power, or the inability to start at all. Howes Diesel Treat is your solution. Both an anti-gel and fuel conditioner, Diesel Treat provides you with all the added benefits your diesel needs while preventing gelling in even the coldest temperatures. Petroleum-based and made with no alcohol or harmful solvents, Diesel Treat is always safe to use.

Even though I have a new 1/2 ton diesel pickup that has all the modern anti gel features this is cheap peace of mind when it goes below 0. Used it for years during the winter, good stuff

I have used Howes Lubricator in my 1997 Cummins for 450k miles it still runs great. We just added a 2024 Cummins to the family. I will use this product from the beginning until I can no longer get it.
