Additional Notes

  • All three engine variants of the Datsun (Nissan) Silvia S12 share an identical manual transmission fluid capacity of 2 liters, indicating a consistent gearbox unit across the 1.8 Turbo, 2.0 DOHC, and 2.0 configurations for the 1984-1988 model years.
  • A 2-liter capacity figure for a manual transmission represents a service fill volume, which is the amount of fluid required when refilling or topping up a unit already in the vehicle, rather than a full overhaul or bench-fill quantity.
  • The check interval for manual transmission fluid across all three variants is set at 10,000 km or 6 months, whichever comes first, applying under normal use conditions.
  • The 10,000 km or 6-month check interval reflects a time-and-distance dual trigger, meaning the shorter of the two thresholds governs when a fluid inspection is due under normal operating conditions.
  • The 1.8 Turbo variant shares the same 2-liter manual transmission fluid capacity and 10,000 km/6-month check schedule as the naturally aspirated 2.0 and 2.0 DOHC variants, despite the added thermal and mechanical load a turbocharged engine places on the drivetrain.
  • The 2.0 DOHC and 2.0 variants carry separate specification entries yet produce identical capacity and interval figures, suggesting the manual transmission unit was not differentiated between those two engine configurations across the 1984-1988 production span.
