From the factory this vehicle uses OE oil filter 12731179. Note the factory fuel filter and front wiper blades are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 federal year-by-year record does not capture 1988; the earliest model year shown is 1990, which logged 41 complaints, 1 recall, 3 investigations, and 2 TSBs. Across the visible generation span, complaints trend downward from 41 in 1990 to 9 in 1993, with investigations spiking to 5 in 1992 and TSBs rising to 12 in 1993 before 1995 closes the file at 1 complaint and 0 recalls. For 1988 specifically, the data shows 17 complaints in Service Brakes, Hydraulic, 3 in Service Brakes, Air, and 1 in Seat Belts, alongside 1 crash complaint and 0 fire complaints, though no root causes are specified. Because 1988 sits entirely outside the federal year-by-year arc, it cannot be benchmarked against that declining complaint curve, and the brake concentration in the available data is the only measurable signal. Given that later years show a clear moderation in complaints and richer federal documentation, 1988 is an uncertain proposition; buyers seeking a lower-risk Allante should favor better-documented later models rather than this pre-record year.
