Fuel Economy?

[scottdm]

We can aspire to fuel consumption measured in gallons/mile just like they do with locomotives

Considering Expys size, that's not a half bad idea.

What sorcery is this? Were you driving downhill, unloaded, on the highway?

Perhaps was being towed behind a motorhome or had a huge tailwind! Best I’ve been able to get is about 20.5 mpg with cruise set at 69 mph.

15mpg

Averaging 19.2 combined driving, which is about what I expected.

I drive slow and steady. Dropped 2 mpg after my tune. After getting bigger tires/wheels, it just got worse.

What tune? I’ve got 5star 93 perf on my 16 and the girl moves!

My 03 Navigator gets about 18-19. Just drive easy. Just got back from a trip in my own 2004 Trailblazer with a 4.2 getting a little over 19 at 62 to 70 all the time.
It seems underpowered and lethargic compared to our 01 Expedition or the Navigator. It will go you just have to give it more gas and let it shift. I prefer our Expedition or the Navigator as you really don't have to give them more gas or just a little bit and they just smoothly move right along.
Not bad they're considering it has 219000 miles and I haven't change the oil in 13,000 miles. I've added about 2 qts but it was way past due for a change. It was fairly dark looking Brown but it was still on the brown side kind of a pukey brown but darker. It wasn't into the black stages yet.
