I got into an accident about a year ago and totalled my H3 and have been looking at a 2004 H2 supercharged recently. I was very happy with the 18-20 mpg I was getting with my h3 but am concerned with the H2. How much worse do you think my fuel economy will be with the supercharger on the H2? It has the supercharger, airaid intake and exhaust.

 

I have a 2005 SUT with a Supercharger and 6 inch lift, and I get about 9-10 miles per gallon, The only bad thing with a super charger is it only uses PREMIUM GAS ONLY........ So if gas is high already, think how much for the good stuff.

 

Got to run premium fuel is the only bad. I have had in my H2 for a few years with a magnacharger, gets around 11 to 12 mpg on average. The cool thing is that when I tow my 24ft car trailer loaded from Sac to Pomona we average around 13 to 14 mpg for the trip. If I had the choice every one of my cars and trucks would have one.
