3.0L EcoDiesel Maintenance Schedule

Ram 1500 EcoDiesel Maintenance Intervals & Service Information

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.

Service Procedure

Recommended Interval

Notes

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

Biodiesel blends greater than B5 have a tendency to cause greater fuel dilution - do not ignore service adjustment

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

Maximum 10,000 mile or 12 month change interval

Maximum 8,000 mile or 6 month oil change interval when using biodiesel blends greater than B5

Drain fuel water separator, replace fuel filter

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

 

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

Replace serpentine belt

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

Inspect at each oil change interval, replace as necessary

N/A - transmission service not specified by FCA

 

Change transfer case fluid

Every 120,000 miles or 12 years under normal conditions
Every 60,000 miles or 6 years if towing frequently or vehicle is used off-road

Replace transfer case fluid immediately if gearbox becomes submerged in water

Change front differential fluid

Every 20,000 miles or 24 months if towing frequent or vehicle is used off-road
Replace immediately if differential is submerged in water
