3.0 EcoDiesel Oil Change Guide

Applicable Models:

2014 - current Ram 1500
2014 - 2019 Jeep Grand Cherokee

Applicable Engine(s):

3.0L EcoDiesel V-6

Ram 1500 and Jeep Grand Cherokee models powered by the 3.0L EcoDiesel are equipped with an electronic oil change monitoring system that will alert drivers via an instrument cluster message when an oil change is required. Under no circumstances should a vehicle be driven more than 10,000 miles/12 months between oil changes. This interval is reduced to 8,000 miles/6 months if using a biodiesel blend greater than B5. When using biodiesel the oil change monitoring system will not compensate for alternative fuel usage, thus users will have to track mileage manually and ensure oil changes are completed at or before the appropriate interval.

3.0 EcoDiesel Engine Oil Spec, Capacity, & Recommendations

Engine oil viscosity spec

2014 - 2019 Ram 1500
2014 - 2019 Jeep Grand Cherokee

5W-40 full synthetic diesel engine oil, API CJ-4
Recommend Amsoil Signature Series synthetic 5W-40 diesel oil

2020+ Ram 1500

5W-40 full synthetic diesel engine oil, API SN, FCA material spec MS-12991
Recommend Amsoil 5W-40 FS Euro spec synthetic 5W-40 diesel oil

Engine oil capacity

2014 - 2019 Ram 1500

10.5 quarts w/ filter change

2014 - 2019 Jeep Grand Cherokee

8.0 quarts w/ filter change

2020+ Ram 1500

8.5 quarts w/ filter change

Note that FCA released a TSB (18-078-16) that retroactively modified the oil specification for all Ram 1500 and Jeep Grand Cherokees equipped with the 3.0L EcoDiesel built before 6/30/2016. This TSB changes the original 5W-30 synthetic oil spec to the newer 5W-40 synthetic spec. All 3.0L EcoDiesel equipped vehicles should therefore receive 5W-40 full synthetic diesel engine oil regardless of any previous oil specification outlined in the owners manual. A 5W-40 full synthetic engine oil meeting API CJ-4 specifications is specified under all operating conditions for 2014 to 2019 model year applications. The oil requirement changed beginning the 2020 model year, requiring an engine oil that meets API SN and FCA MS-12991 specifications. 2020 and newer model years retain the SAE 5W-40 viscosity and full synthetic requirements.

3.0 EcoDiesel Engine Oil Recommendations

Diesel Hub recommends the following Amsoil products for Ram 1500 and Jeep Grand Cherokee models equipped with the 3.0L EcoDiesel:

Amsoil synthetic engine oils offer:

• Superior protection against fuel dilution and oil consumption

• Superior resilience against thermal, mechanical, and chemical breakdown of engine oil

• Improved oil flow and engine protection in sub-zero temperatures and during cold starts

Amsoil is a leading manufacturer of synthetic oils and lubricants, including a line of engine oils engineered to meet the demands specific to diesel engines with modern emissions and exhaust aftertreatment systems.

How to Change the Engine Oil on a 3.0L EcoDiesel (Ram 1500)

positioning oil drain pan

• Park the vehicle on level ground and apply the emergency brake.

• Place a suitable collection pan (minimum 11 quarts capacity) beneath the engine oil pan drain plug.

draining engine oil out of the engine

• Remove the engine oil pan drain plug with a 13 mm socket or box-end wrench.

locating oil filter housing

• Locate the oil filter housing and oil fill tube. The oil filter housing is mounted to the driver side of the engine below the brake booster assembly. The oil fill cap/neck protrudes through the driver side of the top engine cover.

• Open the oil fill tube cap, but do not remove.

removing oil filter housing cap

• Remove the oil filter housing cap with a 27 mm socket. For improved access, you may wish to secure the large vacuum line that travels above the filter housing out of the way (recommend securing it to an adjacent bracket or hose so you will not have to continuously maneuver around it).

removing oil filter

• With the oil filter housing cap removed let the oil drain from the housing for a few moments.

• Remove the oil filter element from the oil filter housing. Used oil filters should be properly disposed of at an oil recycling facility.

replacing oil filter cap o-ring

• Thoroughly clean the oil filter cap and inspect for cracks/leaks.

• Replace the o-ring seal on the oil filter cap. A new o-ring is included with the replacement oil filter element. Lubricate the o-ring thoroughly with clean engine oil.

prepping replacement oil filter element

• Remove the new replacement oil filter element from its packaging and lubricate the o-ring seal with clean engine oil.

installing new oil filter element

• Install the replacement oil filter into the housing, inserting it until the o-ring seats into the hole in the housing (note - only light force is required to seat the o-ring on the nipple of the oil filter).

reinstalling oil filter housing cap

• Reinstall the oil filter housing cap and torque to 25 N-m (18 ft-lbs, 220 in-lbs); do not overtighten.

• If applicable, release the vacuum hose back to its original position.

inspecting and lubricating oil pan drain plug

• Clean and inspect the oil pan drain plug condition. If the gasket/seal is compromised, the drain plug should be replaced (used drain plug with worn seal shown left, brand new drain plug shown right in image).

• Lubricate the drain plug gasket/seal with clean engine oil, then reinstall the drain plug; torque snug, but do not overtighten.

refilling crankcase with engine oil

• Remove the oil fill cap and add the appropriate amount of engine oil. Note the applicable engine oil capacities listed above.

• Replace the oil fill cap after proper amount of engine oil has been added to the crankcase.

verifying engine oil level on dipstick

• Verify engine oil level on the dipstick (passenger side of engine).

• Check the oil drain plug for leaks.

• Start vehicle and check for leaks around the engine oil drain plug and oil filter housing.

• Stop engine, allow vehicle to sit for 10 to 15 minutes, then re-check oil level via engine oil dipstick.
