SLT 3.7L vs R/T 4.0L mileage
My wife's SLT usually averages around 17.6mpg with her behind the wheel. I bought my R/T about 6 weeks later and I am averaging between 20.5mpg and 21.2mpg driving around town (8 miles to and from work) and up and down the mountain which takes me up over 8,000 ft above sea level, and down to about 700 ft above sea level, 3 to 4 times a month. I was concerned about gas mileage before I bought my R/T, but am very happy with what I am getting, considering that both vehicles are 4x4's and my R/T's performance is quite snappy (feels like a sports car compared to my previous ride, Toyota Sequoia Limited). When I take the wheel of the SLT, I am able to almost match the mileage of my R/T, so it is a matter of driving style and the advantage of the extra gear the R/T automatic has. I am sure I could improve mileage even further if I had a manual transmission. So, my advice is to modify your driving style if you want your mileage to be over 20mpg. The Nitro is a heavy truck, not a Honda CRV. Enjoy the difference!
