Can I use 5W-30 instead of 0w20 in Subaru Forester?

Using 5W-30 Instead of 0W-20 in Subaru Forester
When considering using 5W-30 instead of 0W-20 in a Subaru Forester, it’s important to weigh the potential implications and understand the recommendations from various sources.
Subaru’s Official Recommendation:
The official specification for the non-turbo FB engine in the Subaru Forester is 0W-20 full synthetic. However, it’s noted that 5W-30 should be fine, especially in warmer months. Different oil brands can also make a difference in consumption, with oils designed for cars with higher mileage tending to burn off less. It’s mentioned that Valvoline MaxLife, for example, tends to burn off a bit less, and they now make a full synthetic 0W-20 MaxLife.
Local Subaru Dealer’s Input:
A user asked a local Subaru dealer about using 5W-30 oil instead of 0W-20, and the dealer mentioned that using 5W-30 oil might result in an oil light indication due to the higher pressure required to push the somewhat thicker 5W-30 oil through the system. However, it’s worth noting that this statement was criticized as being inaccurate by another user in the same forum.
Community Insights:
In various Subaru forums, users have shared their experiences and opinions on using 5W-30 instead of 0W-20. Some users have reported using 5W-30 without encountering any problems, even after driving 50,000 miles with this oil. Others have mentioned that 5W-30 is somewhat cheaper and easier for shops to maintain stocks of, and it is used on turbo-engines, but it works fine with non-turbo engines as well. However, it’s important to note that 0W-20 is not compatible with turbo engines due to the need for cooling very hot turbos.
In conclusion, while the official specification for the non-turbo FB engine in the Subaru Forester is 0W-20 full synthetic, there are indications that using 5W-30 should be fine, especially in warmer months. However, it’s essential to consider the potential implications and consult with a trusted mechanic or dealership before making a decision.

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.
