Get More Detergency with Premium Dieselex-4 

Diesel engines are susceptible to fuel injector deposits. They always have been. Injector deposits reduce fuel efficiency and lead to costly repairs in all diesel engines, both conventional and modern. Modern Tier 3 and Tier 4 engines are even more prone to injector deposit buildup when typical #2 diesel fuel is used. This is because the holes in the injectors in these modern engines are smaller and far more sensitive to even small amounts of deposits left behind from typical #2 diesel fuel. Operators may not even realize it is happening, but with each hour of operation the deposits slowly grow and engine power is reduced. Over the course of a season or two, engines can suffer very real performance losses.

Preventing Nozzle and Injector Deposits

To insure CountryMark fuels prevent damaging fuel system deposits, our premium diesel fuels contain a unique deposit control detergency package. Our premium diesel fuels has been tested and field proven to eliminate and prevent both conventional nozzle deposits and Internal Diesel Injector Deposits in today’s most complex Tier 3 and Tier 4 engines using high-pressure common rail and other injection systems.

Delivering Engine Power

In a recent study, illustrated in the graph below, #2 diesel fuel was introduced into an engine. As engine deposits added up, power dropped dramatically. In as little as 30 hours, the #2 diesel fuel left behind enough engine deposits to reduce power by more than 7%. When a diesel fuel with adequate detergency was introduced, as noted by the red line, the deposits gradually broke free and engine power returned. Within 20 hours of introducing a diesel fuel with optimal detergency, full engine power was restored.
