1994 GMC Truck Suburban 2WD

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1994 Suburban 2WD.

The 1994 GMC Truck Suburban 2WD Overview serves as a service reference for this two-wheel-drive truck model, specifying a 5.5-quart engine oil fill and a 5W-30 API viscosity grade as its documented maintenance benchmarks. Because the overview confines its verified details to these fluid requirements, it offers researchers a concrete operational baseline without expanding into powertrain or chassis specifics. That focus makes the oil capacity and viscosity grade the central, verifiable data points for this model year.

From the factory this vehicle uses OE oil filter 25160561. Note the factory fuel filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 5,000 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.
