1987 Chrysler Conquest

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1987 Conquest.

Transmission Automatic 4-spd

The 1987 Chrysler Conquest paired its four-speed automatic transmission with an engine oil specification of 4.0 quarts in 20W-20, 15W-40, or 5W-30 viscosities, while returning EPA fuel economy of 16 mpg city, 22 mpg highway, and 18 mpg combined. What makes this particular model year notable for a researcher is the brevity of its reliability record: a single owner complaint logged against the steering system and zero recalls issued across the production run. That near-empty file positions the 1987 Conquest as a high-water mark of dependability within the nameplate's history, offering a useful baseline when charting the model's quality trajectory.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 3,000 mi; spark plugs every 30,000 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.

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 1987 Chrysler Conquest dominate in one area — the steering, 1 of 1 reports (100%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 1 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the steering 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.
