TECHNICAL SPECIFICATIONS 437
regular use of biodiesel between 6% and 20%
requires intervals shorter than the outlined
10,000 miles (16,000 km)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 (12,875 km) or six 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
intervals 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 operating 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%.
