Fuel In Oil Dilution; Biodiesel Fuel Filter Change Intervals - Dodge RAM 1500 2018 Diesel Supplement

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 operating 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 biodiesel requires more frequent fuel filter
change intervals. When operating on biodiesel between
6% and 20%, fuel filter replacement intervals should be
every second oil change, and must not exceed 16,000 miles
(25 750 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 replacement intervals
exceed every second oil change and must not exceed
16,000 miles (25 750 km), if regular operation occurs with
6% - 20% biodiesel blends. Failure to comply with these
Oil Change and fuel filter requirements for vehicles oper-
ating on biodiesel blends up to B20 may result in prema-
ture engine wear. Such wear is not covered by the New
Vehicle Limited Warranty. The engine may suffer severe
damage if operated with concentrations of biodiesel higher
than 20%.
