The diesel engine was invented by Rudolph Diesel in 1893 and has the best thermal efficiency of any normal internal or external combustion engine. That means that it is the best at converting money at the pump into work or power out of the engine. Diesel fuel is more likely than other types of fuel to have problems with incomplete combustion and deposits. Deposits on the injectors, valves or in the combustion chambers negatively impact a diesel engines performance. Prevent the build-up of contaminants in the fuel systems and repository tanks which can quickly clog and congest filters resulting in accelerated fuel pump wear, and ultimately lead to engine failure. If your engine's performance is less than desirable, worry no more... our products can turn it around and give you a dependable engine that will keep going all year around.
