1995 Buick Roadmaster

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

Body PASSENGER CARTransmission Automatic 4-spd

The 1995 Buick Roadmaster is a passenger car that uses a 4‑qt oil capacity with 5W‑30 API lubrication and is paired with an automatic 4‑speed transmission, delivering EPA fuel economy of 15/23/18 mpg. Its reliability record shows 70 total owner complaints, most frequently citing suspension issues, and five recall actions, placing the 1995 model near the peak of complaint volume in the 1991‑1999 span where 1994 recorded 134 complaints and 1999 only one. This pattern indicates that while the 1995 year remains among the more problematic in the lineage, it marks the beginning of a downward trend in reported issues.

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 12737090. Note the factory fuel filter and front wiper blades are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 model year represents a stabilization point in the Roadmaster's federal record, with complaints dropping to 70 from the generation's peak of 134 in 1994, though remaining slightly elevated above the 60 reported for 1996. While recall activity held steady at five campaigns—matching 1994 and exceeding 1996's two—technical service bulletins surged to 35, nearly doubling from the prior year's 18 and indicating intensified factory attention to emerging issues. This year marks the transition from the 1994 complaint spike toward the lower volumes of 1996, yet the data does not specify root causes for the continued suspension, visibility, and electrical grievances that dominate the 1995 docket. With crash and fire complaints totaling six incidents alongside one active investigation, prospective buyers should note that 1995 occupies a mid-generation position where reported failures are declining but manufacturer service guidance is at its most comprehensive, making it a reasonable acquisition provided thorough pre-purchase inspection of the documented complaint areas.
