What is the best gas for a 2005 Subaru Outback?

Answer 1

The best answer is in your owner's manual. You can be sure the owner's manual will give correct information. Different engines require different octane levels. If you do not have an owner's manual, Subaru provides free access to .pdf files on their Web site.

What it says is 87 AKI or higher for non-turbo four and 91 AKI or higher for turbo or six cylinder engines. There are additional recommendations in the manual and you should read them to see if they apply to your location and fuels available.

If you are seeking a gasoline brand recommendation rather than recommended octane, everyone has an opinion and they are of little value.
