FUEL STANDARDS
The quality of fuel is very important to satisfy the engine
performance, extension of engine life and the allowable
exhaust gas level. Doosan engines are designed to use
diesel fuel available in the local market. If the optimum
engine performance is required, select the proper fuel by
referring to the fuel selection table below.
•
Low Sulfur Diesel
NOTE:
High sulphur content in diesel fuel - Doosan
diesel fuel engines can be operated with fuels
whose sulphur content is max. 0.05wt%. Fuels
with a sulphur content of > 0.05wt% are not
permitted as they result in increased corrosion
and greatly reduce the service life of engines.
The oil change intervals must be halved if the
sulphur content is > 0.02wt%.
