Hey all, drove 224.5 miles yesterday up to a distant town to pick up some parts and back. Nearly all hwy miles, mostly interstate-style, other than some through-town miles, some stop signs, etc. No cargo. I got right at 17.0 mpg. (5.7 Hemi, 6 spd, 4x4, 3.55 gearing, not a lot of options, tires properly inflated) which is about what I got the last time I checked it. It runs fine and great AFAIK. On this run it was not in ECO mode all that much due to terrain/winds, or whatever. Sometimes it was, other times not. Speed was generally 68-73 mph.
My old reg cab 89 GMC 4x4 with all the options and 5.7 throttle-body, 4-spd, similar gearing, original dual-bed bead-style catalytic converter and about 275k mi ....gets almost the same or a scootch better! Every time I've checked it in the past for 'average' mileage it was around 16.5 and I've gotten fairly high on straight interstate driving especially if I 'draft' a semi! But overall, most of my driving is hwy.
I was going to rant about the technology not being very effective, but I just went out and looked at the doors and it appears the dodge is about 1000 lbs heavier (6600 lbs). Didn't realize there was that much weight difference (if I'm reading the stickers right). There's a lot greater use of thinner metal, plastics and aluminum than my GMC, but OTOH, trucks in general have increased about 15% larger in size too over the years!!. And sure the Dodge has about 200 more hp. I was driving like an old lady to see if I could get greater MPG.
How are you guys getting 22mpg? Are they 2wd trucks with 6 cyl/8spd getting that? Can you get greater with a 5.7 4x4 6 spd?
At the end of the day I need a tk for the kind of work I do and I'm really happy with this tk. I'm surprised mpg on a flat interstate hwy isn't greater.
