I have a Volvo S80 (year 2001). Can I use regular gas

vs. premium gas as recommended in the owner's manual?

probably...the concern is getting engine knock on the lower octane but the computer running the engine managment should be able to compensate

I was told by the dealership that regular unleaded was perfectly okay to run in my Volvo. I just got it Friday, so I haven't had to fill it yet. It will be interesting to see if it knocks.

Yes No problem at all and no long ter side effects
