Ram 1500/2500/3500: Selection Of Engine Oil For Flexible Fuel Vehicles (E-85) And Gasoline Vehicles

Ram Truck 1500 2500 3500 (2009 - 2018) Owner's Manual / Starting And Operating / Flexible Fuel (3.6L Engine Only) - If Equipped / Selection Of Engine Oil For Flexible Fuel Vehicles (E-85) And Gasoline Vehicles

FFV vehicles operated on E-85 require specially formulated 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 extensive fleet testing, to provide additional protection to Chrysler Group LLC engines. Use MOPAR or an equivalent oil meeting the specification MS-6395.


The characteristics of E-85 fuel make it unsuitable for use when ambient temperatures fall below 0ºF (-18ºC). In the range of 0ºF (-18ºC) to 32ºF (0ºC), you may experience an increase in the time it takes for your engine to start, and a deterioration in driveability (sags and/or hesitations) until the engine is fully warmed up.

NOTE: Use of the engine block heater (if equipped) is beneficial for E-85 startability when the ambient temperature is less than 32ºF (0ºC).

Cruising Range

Because E-85 fuel contains less energy per gallon/liter than gasoline, you will experience an increase in fuel consumption. You can expect your miles per gallon (mpg)/miles per liter and your driving range to decrease by about 30%, compared to gasoline operation.

Replacement Parts

Many components in your Flexible Fuel Vehicle (FFV) are designed to be compatible with ethanol. Always be sure that your vehicle is serviced with correct ethanol compatible parts.

CAUTION! Replacing fuel system components with non-ethanol compatible components can damage your vehicle.


CAUTION! Do not use ethanol mixture greater than 85% in your vehicle. It will cause difficulty in cold starting and may affect drivability.
