Prohibited Additives
The addition of gasoline to diesel fuel will create a serious fire hazard.
Serious personal injury can result.
The following additives are specifically NOT allowed and must NOT be
mixed in with the vehicle diesel fuel:
ț Gasoline — Adding gasoline to diesel fuel will reduce the cetane number
and increase combustion temperature. If a tank contains a diesel fuel/
gasoline mixture, it should be drained and cleaned as soon as possible.
ț Used lubricating oil — Volvo Trucks North America does not recommend
the use of any type of used lubricating oil as an extender in the diesel fuel.
Used lubrication oil contains solids and acids from the combustion
process that can severely corrode parts of the injection system, resulting
in reduced power and higher maintenance cost over time.
Alternative Fuels
Alternative fuels can be of several different types. There are vegetable based
fuels, aviation fuel and recycled petroleum based fuels that are used in
combustion engines. These are in general not compatible with modern
heavy-duty over-the-road diesel engines.
The use of unauthorized fuels may compromise the levels of pollutants in the
exhaust to the point where the engine does not meet the emission
requirements. This would make the vehicle illegal to drive on public roads.
DO NOT use any kind of alternative fuel unless specifically authorized by
Volvo Trucks North America.
