Im able to drive from El Paso to Albuquerque at about 90mph the trip is a little over 200mi on 3/4 tank in my 06 with 112k mi. You might want to have some one check out your hummer bro.

 

I'm never out of the teens when I drive on the interstate with the cc on about 65-70. I think my best ever is about 16mpg.

 

Nice job on digging up a THREE YEAR OLD THREAD!!!!!!!!! WTH?

MPG discussions will never end. someone is and will always be hawking a miracle hp/mpg gadget. i still say 'hard tires,soft foot" !
btw,do i hold the h3,i5,3.7 world record with 19.97. actually at one fill,160 miles,8.0 gal.
cruising down the ohio pike at 65-75??
b4 that trip i had juices changed and put in a $14 advanced auto filter.
so the 3.7 can do it,with 265 rubber. not 285

 

haha 5 cylinders, from reading it seems, im getting about the same you guys are getting with my Alpha. wasnt the H3 I5 "20" MPG?

 

Doc, I got almost 19 once on 285's at 85-90 on the hwy from Dallas to the Ft Hood area but I was drafting two panel vans and hard on their bumper to do it. I hear that if you put large enough magnets on the tailpipe it will "push/pull" you down the road due to all the magnetic reactive re-bar in the roads...but you have to have your tinfoil hat on to block out all the haters.

 

hell i never take a trip w o my tin hat

20 in an alpha i heard once b 4, think ill trade

yeah,a lotta guys in h3,i5 lookin for 18 to celebrate

btw,drafting is no joke,get a semi and u can feel it,20-40 ft i think,,also a little scary
