Penray Plug Fuel, Oil Additives

Penray Plus Diesel Fuel Prep is a technology Penray originally developed for heavy-duty diesel engines. This diesel fuel treatment 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 (DPF), thus extending the life of the emissions control system. The second new product for diesel-powered cars and light trucks is Penray Plus Engine Oil Treatment. Diesel engines are very different from gasoline engines in many ways, including operating with very high compression ratios that require the chemistry of diesel fuels to burn properly. A by-product of this diesel combustion is soot, which can find its way into engine oil past the piston rings and valve guides. The problem with soot is aggravated by the higher levels of Exhaust Gas Recirculation (EGR) present in some diesel engines.
