Bajaj RE series

Differential fluid capacity & service interval

Bajaj RE series differential fluid capacity ranges from 280 CM3 to 300 CM3. Service intervals include checking at 5000 km and changing at 20000 km. The data covers 5 configurations.

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

Additional Notes

  • Across the Bajaj RE series differential specifications from 2013, two distinct capacity values appear: 300 CM3 for petrol-powered 4S variants and 280 CM3 for diesel-powered variants. The 20 CM3 difference between fuel types reflects the distinct gearbox and differential housing designs used in each powertrain configuration.
  • The 300 CM3 differential fluid capacity applies to both the RE Compact 4S and RE Optima 4S, indicating a shared differential assembly across those two petrol variants despite their different trim levels.
  • The 280 CM3 capacity is shared across the RE Compact Diesel, RE Maxima Diesel, and RE Optima Diesel, pointing to a common differential unit used throughout the diesel lineup regardless of trim designation.
  • Among all five configurations listed, only the RE Maxima Diesel includes explicit service interval data. A fluid level check is specified at 5,000 km intervals, with a full fluid change required at 20,000 km under normal use conditions.
  • The 5,000 km check interval on the RE Maxima Diesel differential is notably shorter than the 20,000 km change interval, reflecting a maintenance approach where fluid condition and level are monitored well before a full replacement is due.
  • All five configurations carry a normal use condition designation, meaning the listed capacities and, where present, service intervals apply to standard operating environments rather than severe or heavy-duty duty cycles.
