1993 Chevrolet Corvette

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1993 Corvette.

Transmission Automatic 4-spd

The 1993 Chevrolet Corvette, equipped with an automatic four‑speed transmission, holds four quarts of 5W‑30 API oil and achieves 15 city, 22 highway, and 18 combined miles per gallon. Two recall campaigns have been issued for this model. In its early production years the vehicle attracted only 22 owner complaints, with the most frequently cited problem occurring in the service brakes and hydraulic system, and the lowest complaint count — eight — was recorded in 1992. Consequently, the 1993 Corvette represents a period of relatively low complaint volume, preceding the model’s peak of 588 complaints in 2008.

Fitment & sizes

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

From the factory this vehicle uses OE oil filter 19210286. Note the factory fuel filter, front wiper blades and serpentine belt are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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.

The 1993 model year represents a stabilization point within the C4 generation's federal record, posting 22 complaints—higher than 1992's low of 8 but significantly below 1990's peak of 39—while maintaining 2 recalls and 1 investigation. Unlike the subsequent 1994-1996 period, which saw complaints rise to 40-47 annually with zero recalls, 1993 retained manufacturer recall activity suggesting ongoing support for emerging issues. The data identifies Service Brakes, Hydraulic as the leading complaint category with 4 filings, followed by Electrical System, Vehicle Speed Control, and Engine & Engine Cooling with 2 each, though the specific root causes are unspecified in the federal record. With 4 crash-related complaints and zero fire incidents reported, the safety profile appears contained relative to later model years that exhibit exponentially higher complaint volumes. Given its position after the initial production volatility of 1990-1991 but before the aging-related surge of 1994-1996, combined with active recall coverage absent in later C4 years, 1993 emerges as a favorable acquisition target within this generation.
