According to the search results, it seems that using 5W-30 instead of 0W-20 in a Subaru Forester is generally considered acceptable. Here are some key points from the search results:
– The official specification for the non-turbo FB engine in a Subaru Forester is 0W-20 full synthetic, but using 5W-30 should be fine, especially in warmer months.
– Some Subaru dealers have mentioned that using 5W-30 oil may result in a higher oil pressure and potentially trigger an oil light indication, but this claim is disputed.
– Many Subaru owners have reported using 5W-30 oil without any problems.
It’s important to note that using the recommended oil viscosity, in this case, 0W-20, is generally recommended to ensure optimal performance and fuel efficiency. However, if you choose to use 5W-30 instead, it is unlikely to cause significant issues, especially in warmer weather conditions.
Please consult your vehicle’s owner’s manual or contact a Subaru dealership for the most accurate and up-to-date information regarding oil specifications for your specific model and engine.

Can I use 5W-20 oil instead of 0W-20?
Both 5w-20 and 0w-20 are IDENTICAL once the car is up to temperature. The difference is how thin those oils are when the car is cold. Neither the 0w or the 5w flow enough in the cold to properly lubricate your engine. However, the 0W is thinner and does LESS damage at start up than the 5W oil.
What can I substitute 0w20 with?
SAE 5W-20
If SAE 0W-20 synthetic oil is not available, SAE 5W-20 conventional oil may be used. However, it must be replaced with SAE 0W-20 synthetic oil at the next oil change.
Can I use 5w30 in my Subaru?
Synthetic oil-specifically 0W-20-is highly recommended for optimal engine performance and protection. If synthetic oil isn’t available at the time of an oil change, 5W-30 conventional oil may be used instead. However, it should be replaced with synthetic oil at the next change.
What is the difference between Subaru 5w30 and 0w20?
What weight of Subaru Synthetic Motor Oil should be used? Subaru offers two different SAE weights that vary in viscosity. As shown below, the 5W-30 is specially formulated for turbos that run at hotter temperatures. The 0W-20 is the perfect weight for he non-turbo engine and is formulated for improved fuel economy.
What oil does Subaru prefer?
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 |
Will 5W 20 hurt a 0W-20 engine?
If your owner’s manual says you can use either 0w-20 or 5w-20, then it is O.K..But if your factory manual says only 0w-20, do not use 5w-20 (Unless your vehicle is old & out of Warranty.).
Is it OK if I put 5W20 instead of 0w20?
Simply put, no. Some engine manufactures will say that 5w20 can be installed but 0w20 is preferred, especially if the engine was manufactured before the most recent change in API standards. But most newer engines were designed with tolerances designed specifically with 0w20 being installed.
Can you use 5W-30 in a Subaru Forester?
