Vespa PX

Manual transmission fluid capacity & service interval

Vespa PX manual transmission fluid capacity is 0,25 liter. Service intervals include checks at 5000 km or 12 months, and changes at 10000 km or 24 months and 1000 km or 4 months. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Vespa PX 150 Euro 2 / USA manual transmission holds 0.25 liter of fluid, a small capacity consistent with the compact gearbox design typical of classic Italian scooters in the PX lineage.
  • Under normal use conditions, a fluid level check is scheduled at 5,000 km or 12 months, whichever comes first, with a full fluid change due at 10,000 km or 24 months.
  • An initial service interval is specified separately from the normal use schedule, with a fluid change due at 1,000 km or 4 months after a new fill, reflecting the break-in period for transmission components.
  • The fluid capacity of 0.25 liter remains consistent across both the normal and initial service entries for the PX 150 Euro 2 / USA, indicating no difference in fill volume between a routine change and an early service change.
  • The initial service change interval of 1,000 km or 4 months is significantly shorter than the normal change interval of 10,000 km or 24 months, a gap that reflects the purpose of flushing metal particles generated during early mechanical wear-in.
  • The normal use schedule separates the check interval from the change interval, meaning a technician would inspect the fluid level at 5,000 km without necessarily replacing the fluid until the 10,000 km or 24-month threshold is reached.
