Additional Notes
- The Lotus Elan rear differential calls for a fluid level maintained between the minimum and maximum marks, which is a service fill specification rather than a measured overhaul capacity. A fixed volume figure is absent, meaning the correct level is determined by the position of the fluid relative to those reference points during a top-up or change procedure.
- The service interval for the rear differential fluid is set at 6,000 miles or 9,600 kilometers under normal use conditions. At that mileage, a fluid change is due rather than merely an inspection, reflecting a relatively short drain interval by general automotive standards.
- The normal use condition tied to the 6,000-mile interval applies to the rear differential across the full 1962-1975 production span covered by the specification, with no variation in interval noted between earlier and later model years within that range.
