Diesel School Buses - MFA Oil Boss Diesel


In order to meet today’s tough emissions requirements, the injector must provide an extremely fine mist of fuel to the combustion cylinder. In order to force the fuel through, extremely small holes and high pressure are required.  Because of high temperatures, fuel coking can occur on the tip of the injectors, which partially or completely clogs the holes and disrupts the spray pattern. This results in an incomplete burn inside the combustion chamber, leading to increased emissions and reduced horsepower and fuel economy.

BOSS Performance DieselTM is not only designed to prevent the formation of these deposits, it also cleans up deposits on injectors that have been running on another brand of diesel fuel.
