Ram 6.4 Gas Mileage

ib516, I've enjoyed your posts on the 6.4--don't stop.
The fisherman comment was priceless. I had to think about it for a moment before I got it.
As far as mileage, once I timed it just right, and got 99 mpg towing the trailer, down I-90 off Lookout Pass, for 5.5 miles. When we got home, we averaged 8.5 for the trip.
Each rig is going to tow differently then the next. Our trailer sits pretty high behind the truck and I'm sure the wind beats it pretty badly due to wind flow off the camper shell.

I stand by my numbers, you disagree, and that's ok. I own the truck, I know what empty hwy mpg means, and I know what average mpg means. You apparently aren't so good at reading comprehension.

Go back and actually read what I wrote in the post you mocked, and you'll see we are actually in agreement. If I entered my odometer over fuel used when daily commuting (like fuelly members do) I too would average 13-15 mpg.

What I AM saying is that my truck will get 18 mpg average when running empty hwy at 60 mph, and I have a video to prove it. It will also get 21-22 mpg at that speed when it kicks into 4 cyl mode, and I have video to prove that too - but to be clear that only happens intermittently and under the right conditions.

What I am NOT saying, but you seem to be implying I am, is that I average 18 mpg per tank. I certainly do not get that mpg, not even in my 5.9L Cummins. Again, reread what I wrote.

Here is exactly what I said:

"I get about 8 mpg pulling 12k of 5er, 18 mpg when running empty on the highway, 14 mpg or so in mixed driving, and 11-13 mpg city."

If I get on top of Teton Pass and drive into Victor,Idaho I would probably get like 50 mpg (I have no idea what it would be, except very high). I am not going to then claim that I get 50 mpg, it is misleading and ridiculous. I could take a video of that and it would look good though. The vast majority (minus one 18.1 mpg claim on Fuelly) all are south of 15 mpg. That is still nothing to be ashamed of, big horses have to be fed. There is no value to anyone else when you cherry pick the most optimal driving conditions and claim the resulting mpg as your "mileage". Now if you want to qualify the statement with "when the stars aligns (going downhill with a tailwind), I can see 18 mpg" that puts your statement in a context that we can all relate to. Either way, you have a very nice pickup with big power, it is not
necessary to be misleading on its mpg, it is what it is.

^^^^^^^^ Great post, should be a sticky. :)

The great thing about lots of average numbers is that; well; there're average.

15 MPG towing a TT with an 06 Duramax may be average for some people but it's not average for the average person or me. After 8 years of towing the same TT 10's of thousands of miles I can write in stone that I'm going to "average" 12 MPG when I go on vacation with my TT.

If I have to budget for fuel costs / year (non towing) for my truck, I will budget 16.5 MPG times the mileage I drive. How do I know this? Years and years and years of "average" numbers.

This post is for those that don't understand what 18 mpg highway means. For instance, I drove from my home in New York down to relatives in Delaware, all highway not towing and I got 18 mpg hand calculated. I have a 2014 ram 2500 6.4 with 4.10 gears.

I like going onto fuelly to see what other are getting from their vehicles, tank to tank. You do need to watch some of the reports if they seem to high.. The odd time people put the wrong decimal point on their milage and don't correct it.

2014 RAM 2500 6.4

2015 RAM 2500 6.4

You win Troy - oh great defender of the internet mpg figures !

Here's your crown buddy.

I love how you wear it with enthusiasm!

Surprisingly, there is wind on the way to some fishing spots and even some hills :)

Some guys seeing 18 mpg in a 6.4 and some guys seeing 12-14ish (which is on par with the 6.2 and 6.0 gas from Ford and Chevy). Ram needs to find out what they did right when they made the 18 mpg trucks and replicate it so all of their 6.4s can share in that kind of mileage.

Some Rams were sold to fishermen and some weren't. :B

Now that was about (---------------THIS-------------) funny! :)
