Dodge 2009 Durango - Manual (Page 356)

When you do switch fuel types it is recommended that:
• you do not switch when the fuel gauge indicates less
than 1/4 full
• you do not add less than five gallons (19 L) when
refueling
• you operate the vehicle immediately after refueling for
at least five minutes
Observing these precautions will avoid possible hard
starting and/or significant deterioration in drivability
during warm up.
NOTE: When the ambient temperature is above 90°F
(32°C), you may experience hard starting and rough idle
following start up even if the above recommendations are
followed.
Selection Of Engine Oil For Flexible Fuel Vehicles
(E-85) and Gasoline Vehicles
FFV vehicles operated on E-85 require specially formu-
lated engine oils. These special requirements are included
in MOPAR
௡ engine oils, and in equivalent oils meeting
Chrysler Specification MS-6395. The manufacturer only
recommends engine oils that are API Certified and meet
the requirements of Material Standard MS-6395. MS-6395
contains additional requirements, developed during ex-
tensive fleet testing, to provide additional protection to
Chrysler LLC engines. Use MOPAR
௡ or an equivalent oil
meeting the specification MS-6395.
Starting
The characteristics of E-85 fuel make it unsuitable for use
when ambient temperatures fall below 0°F (-18°C). In the
range of 0°F (-18°C) to 32°F (0°C), you may experience an
increase in the time it takes for your engine to start, and
a deterioration in drivability (sags and/or hesitations)
until the engine is fully warmed up.
