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 system
is designed to provide adequate fuel water separation
capabilities.
Fuel In Oil Dilution — Must Adhere To Required
Oil Change
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 biofuels greater than 5% and less than
20% require intervals shorter than the outlined 18,500
miles (29 773 km) and must not exceed the suggested
schedule. When routinely operating on biofuels greater
that 5% and less than 20%, oil and filter replacement
intervals must not exceed 10,000 miles (16 093 km) or 6
months, which ever comes first.
Biodiesel Fuel Filter Change Intervals
The use of biofuels require intervals shorter than the
outlined 30,000 miles (48 280 km) and must not exceed
the suggested schedule. When operating on biofuels
greater that 5% and less than 20%, fuel filter replacement
intervals must not exceed 20,000 Miles (40 233 km).
NOTE:
• Under no circumstances should oil change intervals
exceed 10,000 miles (16 093 km) or 6 months, if regular
operation occurs with greater than 5% and less than
20% biodiesel blends.
