The use of supplemental fuel additives does not necessarily void the engine
warranty. However, repair expenses which result from fuel system or engine
component malfunctions or damage attributed to their use will not be covered.
Biodiesel General recommendations and guidelines
Detroit
®
supports biodiesel as a renewable fuel. Biodiesel fuels are mono alkali
esters of long chain fatty acids commonly referred to as Fatty Acid Methyl Esters
(FAME) and are derived from renewable resources through a chemical process
called transesterification.
Detroit
®
approves the use of biodiesel fuel blends as follows:
DD Family of Engines - Biodiesel blends up to 5% are allowed
MBE900/4000 Engines - Biodiesel blends up to 5% are allowed
S60 Engines - Biodiesel blends up to 20% are allowed*
*Engines built prior to MY 2004 may contain materials that are not compatible
with biodiesel blends. Biodiesel blends above 5% are not recommended.

Prohibited Additives
The regular use of aftermarket fuel additives is not required or recommended due to
potential engine and aftertreatment damage. These additives increase operating
costs without providing benefit. The use of supplemental fuel additives does not
necessarily void the engine warranty. However, warranty and repair expenses
which are determined, by Detroit™ or its representative, to have resulted from a
fuel additive will not be covered by Detroit™ warranty. For more information on
fuel additives refer to “Lubricating Oil, Fuel and Filters Manual (DDC-SVC-
BRO-0001)”, available through authorized Detroit™ service outlets.
How to Replace the Fuel Filters
NOTICE: If you have just changed the engine oil and filter, you MUST start
the engine and confirm proper oil pressure before changing the fuel filters. If
no oil pressure is shown after approximately 10 seconds, stop the engine
and determine the cause. Running the engine with no oil pressure could
result in engine damage. Start the engine with the accelerator pedal in the
idle position. Monitor the oil pressure gauge or indicator lamp. Keep the
engine running at idling speed until the oil pressure reading is 97 kPa (14
PSI) or more.
