You can put anything in that you want , it is your vehicle . But don’t you think the people who built the vehicle know what to use . What prompted this oil question ? ---

It’s out of warranty, if you want to experiment, that’s your option, but don’t complain if you ruin your engine. ---

Normally 5W30 full synthetic for the 2.0 liter or 0W20 for the 2.5 liter but you can use 5W20, 5W30 or even 5W40 conventional _in a pinch._ [What kind of oil does the 2015 Subaru Forester take?](https://www.vehiclehistory.com/questions/what-kind-of-oil-does-the-2015-subaru-forester-take-8448) For regular maintenance just go with the standard recommendation. ---

Your Forester qualifies for no-cost engine repairs related to oil consumption and engine failure as a result of a class-action lawsuit. You’d be putting that coverage at risk by not using the recommended oil. More here.

3 grades. Mineral, synthetic blend and full synthetic. There are specialty grades of synthetic now. Standard syn used to be the default. Now they have good, better and best synthetic. Platinum synthetic? Titanium synthetic? Zirconium synthetic? ---

Cavelike, you forgot corn, vegetable, olive, and baby oil. Note, I’m including “seed” oils under vegetable oil. ---
