Additional Notes
- The Datsun (Nissan) Silvia S12 rear differential fluid capacity varies by engine variant, with the 1.8 Turbo requiring 1.3 liters versus the 1.0-liter figure shared by both the 2.0 DOHC and the standard 2.0 configurations.
- The 0.3-liter difference between the 1.8 Turbo and the two 2.0-liter variants points to a physically larger differential housing in the turbocharged model, which typically accompanies a unit built to handle higher torque loads.
- All three configurations share an identical service interval of 10,000 km or 6 months under normal use conditions, whichever comes first.
- The 6-month time-based interval running alongside the 10,000 km mileage interval means low-mileage vehicles still fall due for a fluid check on a calendar basis rather than accumulating distance alone.
- The 1.0-liter capacity recorded for both the 2.0 DOHC and the standard 2.0 variants across 1984-1988 indicates a consistent rear differential unit between those two engine configurations despite their differing valve train designs.
- All three rows specify a fluid check rather than a fluid change at the 10,000 km or 6-month mark, meaning the interval governs inspection of fluid level and condition rather than a mandatory drain-and-refill procedure.
