I guess I get to go to every station around me and do this test...wonder what they will think of me slipping the credit card in the pump and purchasing only a pint of fuel...
Is there any way resperate the water after this test, to atleast make the gas good enough to run in my lawn mower or something??

Just having magnaflow exhaust and efan, using tow tune I am getting 18-22 depending on the fuel I get.. Kansas is a state that is supposed to mark the pumps BUT it can be as much as 21% ethenol in Kansas.. 10% is bad enough. 20% you notice the power loss.. and crappy mileage..

Alot has been said. Gas mileage is good/great, depends on how you drive, and maintenance upkeep.
Cruise control is your best friend!!
Highway
65 mph w/ ac running 20-21ish
75 mph w/ ac running 18.9-20 both on flat surface
65 mph w/ ac running 17-19
75 mph w/ ac running 16.5-19 up and down hills
City
AC 12-16 no hurry
AC 10 in a hurry
YES beautimus
No programmer and back to stock exhaust (but to each is own)

need help
Next time buy a Dodge with a Cummins Diesel. I get 29 mpg average (15 with 16000lbs behind it.) I also have a 2003 Dodge with a 5.9 Gas V8 and get 19. I used to get 13 when i first bough it. A good reusable air filter, nice exhaust, headers, and no cats has made a huge difference in mileage. A tuner also helped, but only 2mpg. If you have a diesel, put a boost fooler on it, and 8 inch straight pipe exhaust.
it has 22" rims, intake system and a flowmaster. any advice how to get my mpgs up? any advice would help
thanks

Wow - guys really? We get sucked into mpg questions everyday. Everytime I ask a more specific question I get yelled at for not searching first. This would all be less hurtfull, except the thread originator has 1 post, joined in 2008 (not bad), and hasnt even responded to this thread.......ever.
For life's sake, then I respond....Get a 3865.
