About: 2002 Subaru Outback H6-3.0
H6 fuel requirements
Do these earlier H6 engines require premium fuel? My dad needs a 6 cyl to tow his boat but would not want to spend the extra $$ for premium fuel.
Thanks.

I'm not able to find any specific information about the Subaru H6 engine fuel requirements on the internet. I'm sure regular unleaded is fine!

I have three Subaru's, two are the H6 3.0L. They require premium, they will run on regular but they perform and run cleaner with prem. Run the mileage...it is about the same payout, you lose mpg with regular and gain 2mpg with premium. I drive about 40,000+/year. bigtipper
