1988 Cadillac Eldorado

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1988 Eldorado.

Transmission Automatic 4-spd

The 1988 Cadillac Eldorado features a four-speed automatic transmission paired with an engine requiring 4.5 quarts of 10W-30 or 5W-30 oil, returning an EPA-estimated 15 city and 22 highway mpg for a 17 mpg combined rating. In the broader scope of the model's reliability, this year generated only 10 owner complaints alongside a single recall, with those issues predominantly focused on the engine and engine cooling category. When evaluated against the nameplate's documented complaint history spanning 1990 to 2002—which saw a high of 81 complaints in 1996 and a low of 13 in 1991—the 1988 model sits comfortably near the bottom of the problem spectrum, marking it as a relatively stable iteration for researchers to assess.

Fitment & sizes

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

From the factory this vehicle uses OE oil filter 12731179. Note the factory fuel filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 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 1988 Cadillac Eldorado sits at the very start of the available federal record, with only seven total complaints across all categories and zero reported crashes or fires. This is dramatically lower than the peak years of 19951997, which saw 74–81 complaints annually, suggesting the 1988 model predates the generation’s most problematic period. However, the data does not include any recall information for 1988, and the record only begins in 1990, so it is unclear whether the low complaint count reflects genuine reliability or simply underreporting. The trend of rising complaints and recalls through the early 1990s indicates that later model years suffered from worsening issues, making the 1988 a potentially less troublesome choice—but only if its specific components have been well-maintained over the decades. **Takeaway:** The 1988 Eldorado appears to be a relatively low-risk pick within this generation based on complaint volume, but the absence of recall data means you should budget for a thorough pre-purchase inspection to uncover any latent problems not captured in the federal record.
