Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1997 740IL.
The 1997 BMW 740IL rests on the E38 platform and pairs a 5-speed automatic transmission with an engine that requires a 7.9 quart oil capacity using 15W-40, 10W-40, or 10W-30 API SJ viscosity. Operating with an EPA fuel economy rating of 15/22/18 mpg, this model year generated 19 total owner complaints primarily related to steering and suspension alongside two recalls. When viewed against the 1993-2001 model history, this data places the 1997 vehicle in a middle ground of reliability, falling between the generation's lowest complaint count in 1994 and the peak volume recorded in 1998.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 1997 BMW 740IL marks a notable uptick in reported issues within its generation, with 19 complaints—nearly double the volume of the prior year and the highest since the model’s 1995 peak (12 complaints). While recalls remained stable at two (consistent with 1996), Technical Service Bulletins surged to 16, the highest of any year in the dataset, signaling either emerging systemic concerns or heightened dealer awareness of recurring problems. Complaints cluster most prominently in steering/suspension and engine/cooling systems (four each), areas that also drew attention in adjacent years but without such concentrated volume. The absence of federal investigations suggests no single defect reached critical mass, though the rise in crash- and fire-related complaints (one each) warrants scrutiny. This year falls midway in the generation’s reliability arc, after early teething issues (1995) but before the sharper decline in owner satisfaction seen in 1998 (37 complaints). **Takeaway:** The 1997 model is a higher-risk choice within this generation, demanding meticulous pre-purchase inspection of steering, suspension, and engine systems to mitigate potential long-term costs.
All 19 complaints on record, top 8 components.
