Can I use 5W-30 instead of 0W-20 Subaru Forester?

Using 5W-30 Instead of 0W-20 in a Subaru Forester
When considering using 5W-30 instead of 0W-20 in a Subaru Forester, it’s important to take into account the specific engine type and the potential impact on oil consumption and engine performance.
Turbocharged Foresters with the FB engine use 5w-30 oil. Some owners have considered switching from 0w-20 to 5w-30 to potentially reduce oil consumption, particularly in non-turbo engines. The heavier viscosity of 5w-30 oil may lead to reduced consumption, although it may result in a slight loss of MPG. It’s worth noting that the US market primarily pushes for 0w-20 for these engines, but using 5w-30 has been considered to potentially reduce consumption.
The official specification for the non-turbo FB engine is 0w20 full synthetic, but using 5w30 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 potentially resulting in less oil burn-off.
It’s important to consider the potential impact on warranty, as using an oil not recommended by Subaru could void the warranty. Additionally, it’s advisable to consult with a Subaru dealer or a qualified mechanic before making the switch to ensure it aligns with the specific requirements of the vehicle.
In conclusion, while there are instances where using 5W-30 instead of 0W-20 has been considered, it’s essential to weigh the potential benefits against the manufacturer’s recommendations and warranty implications.

Why does Subaru use 0W-20?

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.

Can I run 5W-30 instead of 20?

Using 5W-30 instead can reduce fuel economy and impede flow throughout the engine. While using it temporarily in a pinch likely won’t cause your engine lasting harm, remember that the engineers who built your engine did so with a specific viscosity oil in mind, meaning it’s best to stick with it.
