So I just rolled over 500 miles on my 2013 screw 4x4 3.55 on our way to Rocky Mountain National Park. I have been getting 12 mpg recently and have been stuck at 13.3 mpg on the master trip that I haven't touched since I got it at 9 miles. So I reset my trip B Friday before work and started to focus on better gas mileage. I will tell you this, 4th gear is the money gear. I have it displayed when I drive so I know where I am and try to keep the shift points appropriately. And it's kinda fun too! Definitely not as fun as 1st thru 3rd gear at 2-6k rpm range! But anyways.... I am currently sitting at 158.2 miles and 20.1 mpg!!! So it can be done!! And this was with 1/3 around town driving and when we went into RMNP we gained about 3,000 ft elevation. And starting at 5,420 ft. I know coming down hill on the way back helped me but I still saw 17mpg on the way up!! Oh Yeah, my master mpg trip went from 13.3 to 14.7!! Sorry I rambled on but point of the story is I changed my driving habits and my mpg's went way way up!! I'll keep a going log and update with anything note worthy. Thanks for reading.
