should be replaced as well. We suggest you change your oil after the first 25 hours and
then every 100 hours or sooner. The cost of the oil is far cheaper then the cost of a new
engine. This is an area where you have great control over how long our generator will
last.
The advantage of synthetic oil is that it can withstand higher temperature and can work
longer without losing its lubricating qualities. It doesn't get thicker at below-zero
temperatures providing good engine lubrication at a cold start. After your generators first
oil change and initial break in period a good quality synthetic oil designed for diesel
engines is recommended. Mobil1 is one of the best ones you can get however make
sure what you buy is specifically for a diesel engine.
About Diesel Fuels
Diesel fuel is principally a blend of petroleum-derived compounds called middle
distillates (heavier than gasoline but lighter than lube oil) and may or may not contain
additional additives. Other middle distillates include kerosene and No. 2 Heating Oil.
Diesel fuel is designed to operate in a diesel engine where it is injected into the
compressed, high-temperature air in the combustion chamber and ignites
spontaneously. This differs from gasoline, which is ignited in a gasoline engine by the
spark plugs.
Ultra-low sulfur diesel (ULSD) will begin replacing conventional diesel fuel starting in
2006. The new fuel will contain 97% less sulfur than conventional diesel—sulfur will be
reduced from 500 parts per million (ppm) to 15 ppm. Sulfur was the main lubricating
property of the fuel. Since the removal of Sulfur from Diesel Fuel diesel shops have
been flooded with work caused by lack of lubrication in the new fuels. Cars, Trucks and
generators can all see the effects of this. Fuel Injector and Fuel pump failure can be
common if the lubrication is not restored by some means. Leading diesel manufactures
now recommend using a fuel additive such as Stantadyne with every fill up to restore to
restore the lost properties from removal of Sulfur
from Diesel Fuel. You should also be using a fuel
additive to avoid similar problems. Stanadyne

How Diesel Engines Fail
Most diesel engine problems are related to the
injection system. As such diagnosing diesel engine
problems requires knowledge of engine and
injection system operation. Excessive diesel
smoke is due to incomplete combustion, normally
caused by faulty injection system or other engine
