Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1995 850CSI.
Built on the E31 platform, the 1995 BMW 850CSI pairs a 6-speed manual transmission with substantial engine maintenance specifications, including an 8.5 quart oil capacity compatible with 15W-40, 10W-40, or 10W-30 API SJ viscosity. EPA estimates rate the vehicle at 10/18/13 mpg, positioning it within a model history spanning 1991 to 1995 that is defined by exceptionally low reported issues. The 1995 model year recorded exactly one total owner complaint regarding exterior lighting, a figure that stands as both the highest and lowest complaint count across the entire period. With only one recall noted alongside this minimal feedback, the data indicates a stable reliability profile for this specific model year relative to the broader production run.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Across the 1991–1995 federal record, this generation shows an unusually quiet complaint profile, with zero owner filings in each of the first four model years and a single complaint logged for the 1995 target year in the Exterior Lighting category. Recall activity was steady at one per year from 1991 through 1993, briefly peaked at two in 1994, then receded to one for 1995, while technical service bulletins held flat at one annually and no investigations were opened in any year of the arc. The lone 1995 complaint carries no associated crash or fire reports, indicating a low-severity issue rather than a systemic safety defect, though the data does not specify the underlying root cause. With 1995 sitting at the tail of the generation — immediately after the recall peak but also the first year to register any consumer complaint — the record depicts a model whose recalls were beginning to taper just as a single, minor category entered the federal database. For a buyer, 1995 is a defensible target year on the strength of the NHTSA data, with the caveat that age-related wear and the higher 1994 recall count warrant verification that prior campaign work was completed.
