The Penray Companies has introduced two products designed to optimize the performance of light-duty diesel engines.

Penray Plus Diesel Fuel Prep is a technology Penray originally developed for heavy-duty diesel engines. It is engineered to keep fuel systems free of deposits and contaminants that can compromise the performance of fuel injectors and other fuel system components, all of which are manufactured to extremely tight tolerances for diesel applications. Keeping injectors clean will minimize plugging of diesel particulate filters thus extending the life of the emissions control system.

The Fuel Prep product also raises the cetane rating of the fuel. Higher cetane numbers accelerate the combustion process to guarantee that the fuel burns where and when it is supposed to for maximum power and efficiency.

The second product, Penray Plus Engine Oil Treatment, combats sooty deposits and other contaminants by dissolving them and holding them in suspension where they can be removed by the oil filter, thus preventing soot and particulates from compromising engine performance and possibly causing engine damage. It includes acid neutralizers to prevent corrosion and also includes supplemental zinc, which fortifies the engine oil.

“As the number of diesel-powered cars, light trucks, and SUVs increases, so does the need for technicians and motorists alike to be aware of the differences in the need for periodic maintenance,” said Mark Kardon, director of marketing for Penray. “While diesel engines do not have spark plugs or conventional ignition systems that require regular tune-ups, they do have issues with both the fuel system and the lubrication system that are different from those that motorists are accustomed to with gasoline engines.”
