Got some new fuel milage numbers for ya'll. I was not trying to conserve fuel on any of these, just normal driving. Also keep in mind I have 33" tires and 3.42 gears, so these numbers could be better with 4.10 gears.

Highway, fairly flat,running 80-85in4th 18.6 mpg
Mountains, running 45-55in 3rd 19.1
Mountains, really steep and winding, running 10-45in 2nd16.6
Highway, fairly flat, running 75-80 in 4th 19.7

I did use the cruise briefly on the last section, but kept downshifting on every hill, so I quit and it never downshifted after. I am inpressed, especially with the numbers in the mountains.

 

Looks good. Now we just need to get 4:10s. And see what happens.

 

I was wondering were you went smoke. High country I take it. Those are good #'s. Looks like I need more mods.

 

Yeah I went t the race in Charlotte, then spent a few days in the mountains. I also had a lot of **** to do before I left and even more when I got back, so I will try to post when I can.

 

You guys get Kelly days up there?

 

Never heard of them so I guess not.

 

I have noticed that I getter better or worse milage depending on the company. I only use name brand companies, so that is all I can comment on. I also use 93 octane since that is what my tune is set for. Anyways here are the results. Hess and 76 are by far the best. 1.5 mpg better thanall others.Then Sonoco andBP/Amoco. I haven't had much Exxon as we don't have any here anymore. I have not tried whatever sams or costco uses, nor smile gas. Anyone else tried to see if they noticed a difference from different companies?

 

My comparisons have been with Racetrack, Shell, and Amoco/BP. BP has given me ~ 1.5 mpg more than Racetrack and ~ 0.5 than shell using 87 octane.
