1995 Buick Park Avenue

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1995 Park Avenue.

Transmission Automatic 4-spd

The 1995 Buick Park Avenue pairs a four-speed automatic transmission with an engine running 4.0 quarts of 10W-30 API oil to achieve an EPA-rated 17 city and 26 highway mpg for a 20 mpg combined average. The model logged 128 total owner complaints and a single recall, with steering faults standing out as the primary area of concern. Within the broader 1994-2005 complaint timeline, the 1995 model sits well below the 301-complaint peak of 1997, meaning researchers will find a moderate reliability footprint dominated by specific steering issues rather than widespread, systemic failures.

Fitment & sizes

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

From the factory this vehicle uses a BCI 78 · 600 CCA battery, OE oil filter 12731175. Note the factory fuel filter and front wiper blades are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 every 7,500 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.

The 1995 Buick Park Avenue sits at the start of a steep upward complaint trend: its 128 complaints more than double the 1994 model’s 56, and while 1996 drops to 59, the generation peaks at 301 in 1997. The single recall in 1995 is low compared to the 2–3 recalls per year from 1996 onward, and no investigations were opened for this model year, whereas later years saw up to four. However, the 27 TSBs in 1995 are triple the 1994 count and signal that dealers were already issuing guidance on emerging issues, particularly in steering (17 complaints), engine/cooling (13), and electrical systems (12). The 5 crash and 3 fire complaints are present but not extreme relative to the generation’s later spike. Given that the 1995 model falls early in the complaint arc and has only one recall, it is a relatively safer choice than the 1997–1998 years, but the data does not specify root causes for its top complaint areas, so a thorough pre-purchase inspection is essential. Overall, this is a passable year to buy if you can verify that the steering and engine issues have been addressed, but it is not the most trouble-free option in the generation.
