We don't have a fully confirmed oil spec for this engine yet
We only label a grade and capacity as confirmed once two independent sources agree on it — an owner's manual plus a genuinely separate witness. Until this engine clears that bar, here's how to get the exact answer for your car in under a minute:
- Grade:read the oil filler cap on top of the engine — most are stamped with the spec (e.g. “0W-20”). The owner's manual lists it too, under maintenance.
- Capacity:the manual's “capacities” or “fluids” table gives the exact quarts, always with the note for whether it includes a fresh filter.
