3.0L EcoDiesel Maintenance Schedule

Ram 1500 EcoDiesel Maintenance Intervals & Service Information

Applicable Models:

2014 - current Ram 1500
2014 - 2019 Jeep Grand Cherokee

Applicable Engine(s):

3.0L EcoDiesel V-6

Select service procedures are required more frequently if using a biodiesel blend greater than B5. Service intervals for these procedures are not affected if using a biodiesel blend of B5 or less. A maximum B20 biodiesel blend is compatible with the EcoDiesel; using a B6 - B20 blend requires a modified maintenance schedule to compensate for the fuel's distinct properties. Frequent towing/hauling and off-road use also affects the recommended intervals of select service procedures.

3.0L EcoDiesel maintenance schedule

Service Procedure

Service/Replacement Interval(s)


Replace engine air filter

Replace every 30,000 miles/36 months, or as necessary

Inspect at each oil change interval, replace as necessary

Change engine oil and replace oil filter

As indicated by the oil change monitor in the instrument cluster display

Do not exceed a maximum 10,000 miles/12 month period between oil changes OR 8,000 miles/6 months if using a biodiesel blend greater than B5 [1].

When using biodiesel blends greater than B5, do NOT follow engine oil change monitor as it will not compensate for interval adjustment; driver must keep track of mileage and service accordingly.

Drain fuel water separator, replace fuel filter

Replace fuel filter every 30,000 miles/36 months when using conventional no. 2 diesel or up to B5 biodiesel blends.

Replace fuel filter every 20,000 miles or 24 months when using a biodiesel blend greater than B5.

EcoDiesel is rated for a maximum B20 biodiesel blend; more concentrated biodiesel fuels may cause premature fuel system component failure

Flush and service engine cooling system

Service cooling system every 150,000 miles or 10 years

Recommend cooling system flush, replacement of thermostat, upper/lower radiator hoses, and overflow tank cap

Replace serpentine belt

Every 100,000 miles/10 years, or as necessary

Inspect at each oil change interval, replace as necessary

Change automatic transmission fluid

N/A - transmission service not specified by FCA

From the Ram 1500 owners manual: "Under normal operating conditions, the fluid installed at the factory will provide satisfactory lubrication for the life of the vehicle."

Change transfer case fluid

Every 120,000 miles/12 years under normal conditions
Every 60,000 miles/6 years if towing frequently or 4 wheel drive is engaged frequently

Replace transfer case fluid immediately if gearbox becomes submerged in water

Change front differential fluid

Every 20,000 miles/ 24 months if towing frequently or vehicle is used off-road

Service interval unspecified under normal operating conditions; replace immediately if differential is submerged in water

Change rear differential fluid

[1] Biodiesel fuels have a tendency to contribute to greater fuel dilution, thus more frequent oil changes are necessary.
