Hi all!! Everyone says why do you buy gas guzzlers and expect half way decent economy? For me, I've always loved the power, but loved a little economy too. Sometimes it's kind of difficult to get to that point though. I have taken it as a challenge, and that is one reason I signed up here. I am hoping to get some pointers to further my quest. About 95+% of my driving is at ~2400-5000 feet elevation. A quick summary of what I have, and I am up against, especially for highway driving:

--Hemi (w/Multi-Displacement System) Dodge Magnum bought new and got 24 mpg at best with 87 fuel. Weighs ~4200 lbs. Now, on a day without headwinds and mountains, it gets no less than 27 mpg, and usually 28-30 mpg using 85, 87, 89, and/or 91 fuel, depending on the type driving and altitude I'll be driving at.

--Hemi (w/MDS) Jeep Grand Cherokee Overland bought used and got 18 mpg with 87 fuel when I bought it. Weighs ~4800 lbs. Now, on a day without headwinds and mountains, it gets no less than 20 mpg, and usually 22-23 mpg using 85, 87, 89 and/or 91 fuel, again depending on the type driving and altitude I'll be driving at.

I am looking forward to hearing suggestions from forum members on how to improve these numbers. Thanks for allowing me to become a member.
