1994 Chevrolet Corvette

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

Transmission Automatic 4-spd

The 1994 Chevrolet Corvette pairs its four-speed automatic transmission with EPA fuel economy ratings of 15/22/18 mpg city/highway/combined. Routine servicing calls for 5W-30 API oil with a 4-quart capacity. Within the model’s 1990–2025 complaint history—a range spanning from the 1992 low of eight owner reports to the 2008 peak of 588—this model year’s 40 complaints and zero recalls place it among the more reliable vintage years, though electrical system issues represent the dominant complaint category.

Fitment & sizes

Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.

From the factory this vehicle uses OE oil filter 25014155. Note the factory fuel filter, front wiper blades and serpentine belt are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 at 7,500 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.

Within the C4 generation's federal record (1990–1996), the 1994 Corvette occupies a transitional position: complaints spike to 40—the highest in the generation's available data—while recalls drop to zero for the first time, and TSBs climb to 8 from 6 the prior year, suggesting GM was addressing emerging issues through service channels rather than formal recall action. The generation's complaint trend is non-linear, falling from 39 in 1990 to a low of 8 in 1992 before rebounding through 1993 (22) and 1994 (40), then holding elevated at 35–47 through 1995–1996. The 1994 model's top complaint areas are the Electrical System (5 complaints), Air Bags (4), Equipment (4), and Power Train (3), with 3 crash-related complaints and 1 fire complaint reported; the data does not specify root causes for any of these. Notably, the subsequent 1995 and 1996 model years also carry zero recalls but show TSB counts jumping to 23 and 21 respectively, indicating that factory-level problem resolution was increasingly handled via technical service bulletins as the platform aged. For a buyer, the 1994 is a mixed proposition: the absence of recalls is reassuring, but the elevated complaint volume—particularly around electrical and airbag systems—warrants a pre-purchase inspection focused on those areas. On balance, it is a reasonable year to buy if the specific car has documented service history addressing the TSB-flagged items, though a 1992 or 1993 with fewer complaints may represent a lower-risk entry into the C4 platform.
