Fuel Water Separation — Must Use Mopar
Approved Fuel Filter Elements
Biodiesel fuel has a natural affinity to water and water
accelerates microbial growth. Your Mopar filtration sys-
tem is designed to provide adequate fuel water separa-
tion capabilities.
Fuel In Oil Dilution — Must Adhere To Required
Oil Change Interval
Fuel dilution of lubricating oil has been observed with
the use of Biodiesel fuel. Fuel in oil must not exceed 5%.
To ensure this limit is met your oil change interval must
be maintained with in the suggested schedule. The
regular use of biodiesel between 6% and 20% requires
intervals shorter than the outlined 10,000 miles and must
not exceed the suggested schedule. When routinely op-
erating on biodiesel between 6% and 20%, oil and filter
replacement intervals must not exceed 8,000 Miles or
6 months, which ever comes first.
Biodiesel Fuel Filter Change Intervals
The use of biodiese requires intervals shorter than the
outlined 30,000 miles (48 280 km) and must not exceed
the suggested schedule. When operating on biodiesel
between 6% and 20%, fuel filter replacement intervals
must not exceed 20,000 Miles (40 233 km).
NOTE:
Under no circumstances should oil change inter-
vals exceed 8,000 miles (12 875 km) or 6 months, if
regular operation occurs with 6% - 20% biodiesel blends.
Under no circumstances should fuel filter intervals ex-
ceed 20,000 miles (40 233 km), if regular operation occurs
with 6% - 20% biodiesel blends. Failure to comply with
these Oil Change and fuel filter requirements for vehicles
operating on biodiesel blends up to B20 may result in
premature engine wear. Such wear is not covered by the
New Vehicle Limited Warranty. The engine may suffer
severe damage if operated with concentrations of bio-
diesel higher than 20%.
