1988 Oldsmobile Cutlass Supreme Classic

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

Transmission Automatic 4-spd

The 1988 Oldsmobile Cutlass Supreme Classic specified an automatic 4-speed transmission, 4 quarts of 5W-30 API engine oil, and EPA ratings of 16/23/18 mpg, establishing a concrete mechanical baseline for researchers. With only 22 owner complaints and two recalls on file, this model year sits on the favorable end of the model's reliability history even as structure represents the top complaint area. That comparatively light grievance footprint makes the 1988 edition a useful benchmark for assessing how these vehicles held up over long-term ownership.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 1988 Oldsmobile Cutlass Supreme Classic dominate in one area — the structure, 7 of 22 reports (32%), well ahead of the next concern. That matters, because the structure are also the target of recall 00V-189 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 3 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the structure pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
