Default Re: Octane for 2008 H2 with the 6.2 L

In my 2008 I only notice a difference using higher octane in the summer months when temps are really high (especially if I am towing). In the cooler months I notice absolutely no difference. The things I notice with the higher octane is increased throttle response along with quicker downshifting and less overall gear hunting.... truck may also seem a tad quicker but that could just be a placebo due to the slightly better response/shifting.
