Subaru Ascent Oil Change Interval & Oil Type
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-06-25
When to change the oil on a 2019-2025 (1st gen; 2023 facelift) Subaru Ascent, and what oil it takes.
| Oil change interval | Every 6,000 mi / 6 mo (full synthetic) |
|---|---|
| Engine / oil | 2.4L FA24 turbo boxer, 0W-20 full synthetic, Lineartronic CVT, Symmetrical AWD |
| Oil filter | Replace with every oil change |
Subaru Ascent note: Symmetrical AWD needs all four tires matched in size and tread (within ~2/32 in) — a mismatch overheats the center coupling and stresses the CVT, so rotate often and replace tires in sets. The turbo likes a brief cool-down idle after hard or towing runs.
