Audi V8 (EU)
Differential fluid capacity & service interval
Audi V8 (EU) differential fluid capacity ranges from 0,5 to 1,7 liters. Service intervals require checks every 15000 km or 12 months. The data covers 3 configurations.

Additional Notes
- The Audi V8 (EU) with the 4.2-litre engine carries two distinct differential fluid capacities depending on which differential unit is being serviced: 0.5 litre for the differential derived from the automatic transmission, and 1.7 litres for the rear differential on 1992-1994 models.
- A 0.5-litre capacity is consistent with a compact differential housing integrated into or closely associated with an automatic transmission assembly, where the fluid volume is relatively small compared to a standalone axle unit.
- The rear differential on the 1992-1994 V8 4.2 holds 1.7 litres, a figure more typical of a dedicated rear axle differential housing with its own separate fluid reservoir.
- All three configurations share an identical service interval of 15,000 km or 12 months under normal use conditions, whichever comes first.
- The interval listed for all configurations is described as a check interval rather than a fluid change interval, meaning the specification calls for inspection of fluid level and condition at 15,000 km or 12 months rather than a mandatory drain and refill.
- The 1991-1992 V8 4.2 and the 1992-1994 V8 4.2 share the same 0.5-litre capacity and 15,000 km/12-month check schedule for the automatic-derived differential, indicating continuity in that specification across the model year overlap at 1992.
