Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1991 750IL.
The 1991 BMW 750IL anchors the E32 platform with an engine requiring 7.9 quarts of 15W-40, 10W-40, or 10W-30 API SJ oil and a 4-speed automatic transmission that yields EPA ratings of 11 city, 17 highway, and 13 combined mpg. Despite its complex mechanical footprint, this specific model year represents the statistical low point for the 750IL's complaint history across the 1990-2001 production run, recording only a single owner complaint focused on Vehicle Speed Control alongside one recall. Consequently, the 1991 model stands as the most trouble-free iteration of the E32 flagship for researchers, contrasting sharply with the peak of six complaints observed in 1998 and signaling an unusually stable entry point into this era of luxury sedans.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 1991 model year opens the documented federal record with one complaint, one recall, and two TSBs—down from two complaints in 1990 and preceding the jump to four complaints seen in 1992. Across the years shown, federal filings trend sharply upward after this early period: recalls reach four annually by 1995, complaints peak at six in 1998, and TSBs climb to seventeen by 1997, placing 1991 at the quietest end of the arc. The data shows zero crash and zero fire complaints for 1991, and its single complaint ties for the lowest volume in the entire record, while its recall and TSB counts remain a fraction of those logged from the mid-1990s onward. Given that federal-record activity escalates significantly in later model years, 1991 stands out as a comparatively low-risk purchase within this dataset.
