Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1990 735IL.
The 1990 BMW 735iL rides the E32 platform with a four-speed automatic transmission, carrying an oil capacity of 6.1 quarts of 15W-40, 10W-40, or 10W-30 API SJ lubricant and EPA fuel-economy ratings of 14 mpg city, 20 mpg highway, and 16 mpg combined. Within the model’s 1990–1992 production span, this inaugural year records the lowest complaint volume—just one owner-reported issue concerning Vehicle Speed Control—alongside a single recall. That solitary documented report establishes 1990 as both the highest and lowest complaint year in the brief reliability history, positioning it as the definitive baseline with the fewest reported problems.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 1990 BMW 735IL sits at the front of a three-year federal record (1990–1992) characterized by very low complaint volume but a modest upward trend in recalls. In the target year, federal data shows a single complaint—centered on Vehicle Speed Control and linked to a crash incident—alongside one recall, zero investigations, and one TSB. The following two model years each saw recall counts double to two, while complaints held at one (1991) then dropped to zero (1992), and TSBs held steady at one across all three years, suggesting BMW was actively addressing issues through recalls rather than leaving them to consumer-initiated complaints. The data does not specify the root cause behind the 1990 speed-control complaint or the recall, so no definitive mechanical conclusion can be drawn from the record alone. Importantly, the target year carries the lowest recall burden of the generation and no NHTSA investigations, placing it at the more favorable end of the arc. For a buyer, 1990 appears to be a marginally better entry point than 1991 or 1992 from a federal-record standpoint, though the single crash-associated speed-control complaint warrants a specific pre-purchase inspection of throttle and cruise-control systems.
