How much oil does a EJ20 take?
The EJ20 typically takes about 5 quarts (4.8 liters) of engine oil with a new filter during a full oil change. Exact capacity depends on variant, oil pan size, and whether the filter is replaced, so always verify against your specific model’s manual.
The EJ20 is Subaru’s 2.0-liter flat-four used across multiple generations and configurations, including turbocharged and naturally aspirated variants. Because the engine variants differ in pan design and ancillary components, the oil capacity can vary slightly. For precise figures, refer to the exact engine code (for example EJ20G, EJ20K, EJ20X) in the owner’s or service manual.
Common EJ20 oil capacity by variant
The following values cover typical EJ20 configurations and assume the oil filter is replaced during the change. Exact numbers can vary by year and equipment, so use these as a guideline and confirm with the official manual.
- EJ20G / EJ20K (turbocharged, WRX/STi variants): approximately 5.1 quarts (4.8 liters) with filter installed
- EJ20E / EJ20X / other naturally aspirated 2.0L variants: roughly 4.8–5.0 quarts (4.5–4.7 liters) with filter
- Other rare or market-specific 2.0L EJ20 configurations: commonly around 4.7–5.0 quarts (4.4–4.7 liters) with filter
Because oil pan sizes and gasket layouts differ between variants and model years, always confirm the exact capacity from your vehicle’s service manual or Subaru technical documentation. After filling, recheck the level with the dipstick to ensure you reach the correct full mark without overfilling.
How to check and fill the EJ20 correctly
Follow these steps to ensure you add the correct amount of oil and avoid overfilling or underfilling.
- Warm up the engine to operating temperature, then turn it off and wait several minutes for the oil to settle.
- Park on level ground and open the hood. Locate and remove the oil fill cap to allow air to escape.
- Dip the oil level with the dipstick, wipe it clean, reinsert fully, and pull out to check the current level.
- If the level is below the "Full" mark, add oil in small increments (about 1/4 quart or 0.25 liters at a time) and recheck after each addition.
- Continue until the dipstick shows the level at or near the full mark. Replace the dipstick and oil fill cap securely.
- Start the engine and let it run for a minute, then recheck for leaks and recheck the dipstick again after a few minutes to confirm the level.
Be careful not to overfill, as oil that’s too high can foam and cause engine damage. If you accidentally overfill, drain some oil to return to the correct level.
Summary
For most EJ20 engines, plan on about 5 quarts (4.8 liters) of oil with a new filter for a full change. Variant-specific figures typically fall within 4.8–5.1 quarts (4.5–4.8 liters). Always verify with the exact engine code in the owner’s or service manual, and use the dipstick to confirm the correct level after filling. Regularly checking oil capacity and level helps maintain engine health across the EJ20’s diverse applications.

How much oil does a 2.0 liter engine take?
A 2.0-liter engine typically takes between 4.4 and 6 quarts (about 4.2 to 5.7 liters) of oil, but the exact amount depends on the specific vehicle and engine model. You should always check your vehicle's owner's manual for the precise capacity, as it is the most accurate source of information for your car.
| Vehicle Example | Estimated Oil Capacity |
|---|---|
| Honda Civic (2.0L non-turbo) | Approximately 4.4 quarts (4.2 liters) |
| Ford F-150 / F-250 (2.0L EcoBoost) | Approximately 5.7 quarts (5.4 liters) |
| Chevy Equinox (2.0L turbocharged) | Approximately 5 to 6 quarts |

Important tips
- Check your owner's manual: This is the most accurate way to confirm the correct oil capacity for your specific vehicle.
- Account for the oil filter: Most capacity estimates are for a full oil change, which includes replacing the oil filter.
- Don't overfill: After refilling the oil, always check the dipstick to ensure the level is within the recommended range. Overfilling can cause engine damage.
