Manual transmission fluid capacity & service interval
Volkswagen (VW) VW-Porsche 914 (EU) uses manual transmission fluid with a capacity of 2,5 liters. Service intervals include checking at 5000 km and changing at 20000 km. The data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |

Additional Notes
- Both the 914/4 and 914/6 variants share an identical manual transaxle fluid capacity of 2.5 liters, which is a typical fill volume for a combined gearbox-and-differential transaxle unit of that era, where the transmission and final drive share a common fluid sump.
- The Volkswagen-Porsche 914 uses a transaxle layout, meaning the gearbox and differential are housed together at the rear axle, and the 2.5-liter capacity reflects that combined internal volume rather than a standalone gearbox fill.
- A fluid level check interval of 5,000 km applies to both the 914/4 and 914/6 under normal use conditions, indicating a relatively frequent inspection cycle consistent with the maintenance standards of 1969-1973 production vehicles.
- The fluid change interval for both variants is set at 20,000 km under normal use conditions, which is a moderately short drain interval by contemporary standards and reflects the lubrication technology available during the early 1970s.
- The 5,000 km check interval and 20,000 km change interval together establish a four-to-one ratio between inspections and full fluid changes, meaning the transaxle fluid level is verified four times before a complete drain and refill is due.
- No difference in capacity or service intervals exists between the four-cylinder 914/4 and the six-cylinder 914/6, despite the two variants using mechanically distinct powertrains, suggesting the transaxle casings shared the same fluid volume specification across both configurations for the 1969-1973 model years.
