All Howes Diesel Fuel Additives comply with the federal low sulfur diesel requirements (<15ppm) for use in diesel motor vehicles and non road engines.

Our additives are safe to use in any diesel engine, including '07 and beyond. Howes products demulsify water, contain no alcohol, are particulate filter friendly and will not void any manufacturers warranty.

The U.S. Environmental Protection Agency (EPA) regulations intended to improve our air quality went into effect June 1, 2006. They require a major reduction in the sulfur content of diesel fuels and emission levels from diesel engines and vehicles. To meet the EPA standards manufacturers have developed new, highly advanced emission control systems and the petroleum industry is producing ULSD fuel, a cleaner-burning diesel fuel containing a maximum of 15 parts-per-million (ppm) sulfur.

All diesel engines manufactured after 2007 will be equipped with advanced emissions control systems. While they will be extremely effective in reducing emissions, they are susceptible to damage from higher concentrations of sulfur. Owners of 2006 and earlier diesel vehicles may use either ULSD or LSD fuel where it is available.

Starting in 2010 most new engines will be equipped with SCR (Selective Catalytic Reduction System) to reduce NOx emissions. These engines will require the use of DEF (Diesel Exhaust Fluid) as a catalyst. This fluid is injected into the exhaust after combustion and is not affected by Howes Products. Some engines will use EGR technology and are also not affected by the use of Howe's additives.

Howes products will clean and lubricate fuel injectors, pumps and upper cylinders, adding back lubricity lost in the refining process. Howes Diesel Treat will continue to give you protection against gelling and still carries our famous guarantee - “You Go or We Pay the Tow!”

We would like to inform you about some differences between U.S. and Canadian ULSD requirements. As of June 1, 2006, all production in Canada of diesel fuel must be 15 ppm sulfur or less. As of September 1, 2007, only ULSD fuel is allowed to be sold at the retail level.

Diesel fuel additives are not addressed in Canadian regulations, so there are no corresponding labeling requirements as in the US. It is again important for Canadians to remember, Howes Lubricator Diesel Treat and Meaner Power Kleaner are safe for all diesel engines, including 2007 and newer.

Should you require further information or clarification, please contact our Sales Department at 1-800-438-9080.

I did a test on Howes Diesel Conditioner in our Transit buses. On our downtown runs the mileage increased 10-12% and the runs which do the highways increased as much as 16%.
