2018 Ram Pro Master — 3.6L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 Pro Master 3.6L.

Engine 3.6LTransmission Automatic 9-spd

The 2018 Ram ProMaster 3.6L is a full-size cargo van built on the VF platform and powered by a 3.6L engine paired with an automatic 9-speed transmission, a combination that carries EPA ratings of 21/28/24 mpg and calls for 5W-20 engine oil with a 6.0-quart capacity. In the model's reliability record, this year stands out for drawing 37 owner complaints and 10 recalls, with the Power Train category accounting for the largest share of reported issues. That concentration of powertrain-related feedback, alongside the recall count, makes the 2018 model a useful benchmark when researching how this generation has held up in service.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; spark plugs every 100,000 mi; coolant every 10,000 mi. The big-interval services (every 10,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2018 Ram Pro Master top in one area — the power train, 5 of 37 reports (14%), well ahead of the next concern. That matters, because the power train are also the target of recalls 20V-036 and 20V-582 on this vehicle — so the single most useful check before buying or servicing one is confirming they were actually performed. 4 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the power train pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
