Why does Subaru use 0W-20?
Subaru recommends the use of 0W-20 synthetic motor oil for their non-turbocharged engines. This choice is based on several factors:
1. Engine Design: Subaru’s non-turbocharged engines have a low-friction design that benefits from the use of a low-viscosity oil like 0W-20.
2. Fuel Economy: The use of 0W-20 oil helps improve fuel economy, which is an important consideration for Subaru and their customers.
3. Warranty Considerations: Subaru strongly advises using the recommended oil weight to avoid potential warranty challenges and engine performance issues. Using a different oil weight may shift the burden of proof in a warranty claim to the vehicle owner.
It’s important to note that using the recommended oil weight is generally recommended to ensure optimal engine performance and to maintain the warranty coverage. While some Subaru owners may consider using a different oil weight, it’s advisable to consult the vehicle’s manual and consider the potential impact on warranty coverage before making any changes.

Does Subaru Outback use 5W-30 oil?
Subaru Outback 2002 to 2012: 5W-30 Conventional Oil. Subaru Outback 2013 to 2023: 0W-20 Synthetic Oil. Subaru Outback (6-Cylinder) 2002 to 2019: 5W-30 Conventional Oil. Subaru Outback (6-Cylinder) 2020 to 2023: 5W-30 Synthetic Oil.
What is the best oil for Subarus?
Subaru Oil Guide:
| Model | Subaru Oil Required | Capacity |
|---|---|---|
| Subaru Legacy & Outback XT (Turbo) 2020 – 2021 | 0W-20 Synthetic Oil | 4.8 Quarts |
| Subaru WRX 2002 – 2010 | 5W-30 Conventional Oil | 4.4 – 5 Quarts |
| Subaru WRX 2011 – 2020 | 5W-30 Synthetic Oil | 4.4 – 5.4 Quarts |
| Subaru Crosstrek 2013 – 2021 | 0W-20 Synthetic Oil | 4.4 – 5.1 Quarts |
Is there a big difference between 0w-20 and 5W-20 oil?
So, 0W20 means the oil’s viscosity is 0 in cold temperatures and 20 at the operating temperature. The 5W20 oil is the same except for a viscosity of 5 in cold temperatures. Both oils are designed to use in cold-weather regions. However, these multi-grade oils can perform in hot weather too, although not extremely hot.
What happens if you use 5W-30 instead of 0w20?
What happen if my car requires 0w20 and I put 5w30? Absolutely nothing. Completely. It almost literally doesn’t matter, except at the outer limits in super cold climates… and then only maybe.
What happens if I use 20W50 instead of 0W20?
The recommended oil for the Outlander is 0W20, or in some vehicles 5W20. 20W50 is a thicker more viscous oil. This means more effort is needed to pump this thick oil through the engine. Using a thicker oil can result in oil pump wear and overall engine wear in especially in cold climates.
Can I put 5W-30 instead of 0w20 Subaru Outback?
Like the Crosstrek, the oil for the Subaru Outback needs to be an API classification SN or ILSAC GF-5. Also like the Crosstrek, the Outback engine should be filled with 0W-20 synthetic oil. If synthetic oil isn’t available, you can use either 5W-30 or 5W-40 conventional oil.
Is 0W20 good for hot weather?
0W-20, for example, is rated at 104°F (40°C) for external temperatures, and 212°F (100°C) for internal engine temperatures. So, the 0W rating of most oils, including ENEOS, is within operational parameters of warmer climates like Hawaii, Phoenix, and Las Vegas.
What oil does Subaru use from the factory?
Synthetic 0W-20 is uniquely formulated to handle the low-friction design of Subaru non-turbocharged engines. Synthetic 5W-30 motor oil is required for 2011 and newer turbo-charged engines, and is recommended for prior year models.
What happens if I use 0W-20 instead of 5W 20?
The 0W or 5W refers to the pumpability in cold temperatures. Therefore, a 0W would flow more easily than a 5W and could be an acceptable substitute. Thus, it is suitable to use a SAE 0W-20 as a replacement for SAE 5W-20 application. **Offers same protection as 5W but also provides faster flow and better fuel economy.
Can I use 5w20 instead of 0w20 Subaru crosstrek?
I wouldn’t hesitate to use a good 5w20 in place of 0w20. The only thing that *could* be an issue is if you had potential lubrication related issue and a dealer or Subaru wanted to see your oil change receipts, and it showed 5w20 on the paperwork.
