Subaru Crosstrek, GT (USA / CAN)

Manual transmission fluid capacity & service interval

Subaru Crosstrek and GT manual transmission fluid capacity ranges from 3,3 to 3,5 liters. Service intervals include checking at 30000 miles or 30 months and changing at 15000 miles or 15 months. The data covers 8 configurations.

Additional Notes

  • The Subaru Crosstrek 2.0i from 2015-2017 carries a manual transaxle fluid capacity of 3.5 liters, which is 0.2 liters more than the 3.3-liter figure shared by all subsequent 2.0i and 2.5i configurations.
  • Starting with the 2017-2019 Crosstrek 2.0i, the manual transaxle capacity dropped to 3.3 liters and remained at that figure across the 2019-2023 2.0i and the 2020-2023 2.5i variants.
  • Under normal use conditions, the manual transaxle across all listed configurations calls for a fluid check at 30,000 miles or 30 months, rather than a full fluid change.
  • Under severe use conditions, the interval shifts to an actual fluid change at 15,000 miles or 15 months, half the distance and time span of the normal-use check interval.
  • The distinction between a check under normal conditions and a change under severe conditions reflects meaningfully different service demands on the transaxle fluid, with severe use accelerating fluid degradation enough to warrant replacement rather than inspection alone.
  • The 2.5i engine variant, available from 2020-2023, shares the same 3.3-liter manual transaxle capacity and identical service intervals as the 2.0i configurations from the same period, indicating no capacity or scheduling difference between the two engine displacements in the manual transaxle application.
  • The 2017 model year appears in two separate specification rows, once as part of the 2015-2017 2.0i group with a 3.5-liter capacity and once as the start of the 2017-2019 group with a 3.3-liter capacity, reflecting a mid-cycle specification change during that year.
