Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1989 750IL.
Riding on the E32 platform and driven through a 4-speed automatic transmission, the 1989 BMW 750iL demands a substantial 7.9 quarts of oil—specified at viscosities ranging from 10W-30 to 15W-40 API SJ—to feed a powertrain returning a mere 11 city and 16 highway mpg for a 13 mpg combined average. That mechanical thirst carries over into its reliability record, where six total owner complaints focused heavily on the engine and engine cooling, alongside two separate recalls, tie this model year with 1998 for the highest complaint volume across the 1990-2001 spectrum. Consequently, occupying the top of the model's complaint history means the 1989 750iL stands as a notably problematic entry for researchers, indicating that these early examples carry inherent mechanical risks.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The federal record for the 1989 BMW 750IL is notably sparse: the year-by-year data begins in 1990, so no complaints, recalls, or TSBs are listed for the target year itself. However, the separate target-year summary shows four complaints (one each in Engine & Engine Cooling, Vehicle Speed Control, Electrical System, and Seat Belts) and two crash complaints, with zero fire incidents. This places 1989 at the very start of the generation’s arc, before the complaint and recall numbers climb in the mid-1990s—for example, 1995 had three complaints and four recalls, and 1998 had six complaints. The trend across the generation shows a clear escalation in both recalls and TSBs from 1995 onward, peaking in 1997 with 17 TSBs, suggesting that later model years experienced more documented issues. Because the 1989 model lacks any federal record entries, it may have avoided the systemic problems that triggered later recalls, but the data does not specify root causes for its own complaints. **Takeaway:** The 1989 750IL is a relatively low-documentation year, but with four complaint areas and two crash reports, it is not risk-free; a thorough pre-purchase inspection is essential, and it may be a better buy than the more heavily recalled mid-1990s examples.
