How much oil goes in a Subaru Impreza?
Most Subaru Impreza models require roughly 4.4 to 4.8 quarts of engine oil with a new filter, depending on the engine size. Always verify the exact capacity for your year and engine in the owner's manual or on the oil-fill cap sticker.
Understanding the numbers
Oil capacity reflects the amount needed to fill the engine’s oil passages and the filter. The Impreza has used a few different engines over its generations, so capacity varies by engine displacement. Below are typical figures for the two most common Impreza engines in recent years. Exact numbers can differ slightly by model year, presence of an oil cooler, or the specific filter size, so always double-check your vehicle’s documentation.
2.0-liter engine
Typical capacity with a standard oil filter:
- About 4.4–4.5 quarts (roughly 4.2–4.3 liters) of oil when changing the oil and replacing the filter.
Note: This range is common for many 2.0L Impreza variants; always confirm with your vehicle's manual or the stamped capacity on the oil filler cap.
2.5-liter engine
Typical capacity with a standard oil filter:
- About 4.8 quarts (roughly 4.5 liters) of oil when changing the oil and replacing the filter.
Note: Some older or different-spec models may show slightly different numbers; check your owner's manual for the exact capacity.
How to confirm the exact quantity for your car
To be certain of the oil capacity for your specific Impreza, use one of these methods:
- Check the owner's manual's maintenance section, which lists oil capacity for your engine.
- Look at the oil-fill cap or the under-hood sticker; many cars print the capacity there.
- Enter your VIN and vehicle details on Subaru's official support site or consult the dealer.
Once you know the capacity, prepare a little extra to top off if needed after initial drainage, and always measure with a clean container and a funnel to avoid overfilling.
Summary
In short, plan on about 4.4–4.5 quarts for the 2.0L engine and about 4.8 quarts for the 2.5L engine, including the filter. Always verify the exact number for your specific year and engine, and consult the owner's manual or dealer resources if in doubt. Regular oil changes with the correct quantity help protect the engine and keep performance up to par.
