It’s easy to forget the importance of regular vehicle maintenance, but changing the oil is one of the simplest, most essential ways to enhance your Subaru vehicle’s performance and increase its lifespan.
While the general recommendation is that you should change your oil every 3,000 miles, newer vehicles can keep the oil churning for 5,000 to 7,000 miles.

How Much Oil Does A Subaru Impreza Take?
2022 2.0L 4-cyl FB20 engine Subaru Impreza takes 4.6 quarts (4.4 liters) with a filter of 0W-20 oil. The Subaru Impreza can use either synthetic or conventional oil. On average, synthetic oil runs for 5,000 miles longer than the latter.
Engine Oil Consumption
While driving, some engine oil will be used up. The rate of consumption can be influenced by such elements as gear shift type, driving style, terrain, and weather. Oil consumption may be enhanced under the following circumstances:
- When the engine is new and within the break-in period;
- When the engine oil is of lower quality;
- When the incorrect oil viscosity is used;
- When engine braking is employed (repeatedly);
- When the engine is operated at high engine speeds (for extended periods of time);
- When the engine is operated under heavy loads (for extended periods of time);
- When the engine idles for extended periods of time;
- When the vehicle is operated in stop and go and/or heavy traffic situations;
- When the vehicle is used under severe thermal conditions;
- When the vehicle accelerates and decelerates frequently.
Under these or similar circumstances, you should check your oil at least every other time you fill up the tank and replace the engine oil more frequently. Different motorists in the same vehicle may have varying experiences. If your oil usage is greater than anticipated, contact an authorized SUBARU dealer who can perform a test under controlled conditions if necessary.
Types Of Engine Oil
The viscosity of engine oil has an impact on fuel efficiency. Engine oils of lower viscosity deliver better fuel economy. Oil of greater viscosity is required in hot weather to efficiently lubricate the engine.
Full Synthetic Engine Oil
This sort of motor oil is designed for high-performance automobiles that require a lot of lubrication. It’s resistant to oxidation and thermal failure and has greater viscosity, and prevents oil residue. When the engine pull reduces, full synthetic improves horsepower efficiency by enhancing volume. It costs four times more than normal motor oil.
Synthetic Blend Oil
Synthetic blend oil is the ideal combination of both worlds and costs less than full synthetic oil. It incorporates some synthetic and conventional additives to give greater oxidation resistance and good performance at low temperatures by combining synthetic and conventional oils.
Conventional Oil
Engine oil of this type is the most popular. It’s perfect for small engines and cars with low mileage.
High Mileage Oil
This oil is designed specifically for cars with 75,000 miles or more.
The oil I was using for my car was only rated to 5 quarts, but I have since gotten a few more and have been using them on all my engines since. I did a little research and came up with 2 different types of oil, the type I was using had higher viscosity and I would expect a higher performance from the engine, I decided to try a lower viscosity one.
My new oil changed the car’s idle speed from 20,000 rpm to 25,000 rpm. I have since tested and it was not because of the lower viscosity oil, and in fact, it has not changed any idle speed on my car. The lower viscosity oil did not cause any changes in any other aspects of my car, including the engine’s oil pressure. The one thing I do know is that it is a much better oil than the previous one, and it has not changed the idle speed on my car.
Hi, Val.
In case of using the recommended oil viscosity range (above in article) the car’s idle shouldn’t change. Having this problem, I would say it’s not because of oil.
What brand of oil does Subaru recommend?

Can you use 5w 30 instead of 0w 20?
Hello. Yes, sure. It is allowed by off. owner manual.
