Cool Re: 2008/2009 owners..... Premium fuel question??
I have only had my H2 for about three months but I only use 93 octane fuel (I just got used to it with the 2007 Vette that I traded for the Hummer) so I do not know how well or poorly it runs on lower octane. I only drive mine on the weekends so paying for premium fuel is not that big a deal to me.
