Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1992 RAM 5.9L. Covers both the standard and High Output 5.9L.

Body TRUCKEngine 5.9LTransmission Automatic 4-spd

The 1992 Dodge RAM 5.9L is a full-size pickup truck built on the AD platform and powered by a 5.9-liter engine paired with a four-speed automatic transmission, achieving EPA fuel economy ratings of 17 mpg city, 21 mpg highway, and 19 mpg combined, while requiring 5 quarts of oil with filter using 10W-30 or 5W-30 API-grade viscosity. This model year recorded 71 owner complaints with service brakes and hydraulic systems emerging as the primary concern area, and the vehicle was subject to two safety recalls during its production cycle. Within the broader RAM complaint history spanning 1990 to 2011, the 1992 model year falls between the lowest complaint year (1990 with 23 complaints) and the peak complaint year (2001 with 1,468 complaints), indicating relatively moderate reliability concerns compared to later model years.

From the factory this vehicle uses OE oil filter 05281090AB. Note the factory engine air filter, fuel filter, spark plug and serpentine belt are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 12,000 mi; spark plugs every 30,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 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.

The 1992 Dodge RAM sits at the end of a stable early-generation period, with 71 complaints, 2 recalls, 1 investigation, and 18 TSBs—nearly identical to 1991’s 71 complaints but down from that year’s 3 recalls and 2 investigations, and well above 1990’s 23 complaints with zero recalls or investigations. Compared with 1993, which recorded 66 complaints, 1 recall, 2 investigations, and 18 TSBs, 1992 is effectively flat, placing it in a low-activity plateau before the generation’s federal-record volume surges dramatically in 1994 with 710 complaints and 23 recalls. The leading 1992 complaint categories are service brakes/hydraulic (10), fuel system/gasoline (9), engine and engine cooling (7), and steering (6), with 4 crash-related and 2 fire-related complaints; the data does not specify root causes. Across the broader arc, reported problems remain comparatively contained through 1993 and then escalate sharply from 1994 onward, so 1992 represents one of the quieter model years in this generation. For a buyer prioritizing lower exposure to recall and investigation activity relative to later Rams, 1992 is a comparatively favorable year to buy, though the brake, fuel, engine, and steering complaint counts still warrant a thorough pre-purchase inspection.
