It looks like you can't even agree with yourself. [emoticon]

I agree that diesels get better mpg that gasoline engines. But that gap is closing with the push for more power and better emissions.


I get 11.5 towing 13K+ through the mtns

And I never said I made more hp. My 7.3 was rated @ 250 and with my mods I've gained about 80 more. BUT it will out tow a gasser with equal wgt. But I will never convince these gasser owners till one steps up to a contest. Don't believe everything you see on youtube.


Why not post your own Youtube video of your truck towing your 13k lb 5th wheel up a steep grade. Others have done it. 11.5mpg towing 13k in the mountains? My Cummins Rams only gave 10.5mpg at 68~mph average around the southeast.

I don't have a video camera and my old flip phone doesn't do it very well. I'll see if I can get one from a friend. Yes, on a one way trip for Phx to Showlow, Az with several 6/7% pulls hand calculated 11.5. I get 16/17 around town but I don't drive agressively. My right foot is a big help. I also have stock inj & turbo. I tow in my 40T on the steep stuff & in 20T everyplace else.

I'll be going up for a week before & including Labor Day so I'll try and get some video.

There is a guy I know that's on here once in a while that has towed with me ask him. He goes by " Slated for greatness" He's the only one that gives me fits. He has a 6.0 Tow Boss with 4.30's & the bullit proof stuff. His tows really well.

Hannibal, look at the map and you'll see the trip I spoke of. Not sure if it gives altitude but here it's about 1200' and there about 4 6/7% pulls and then after topping the rim it's 8200' and then the last 60/70 miles is rolling hills dropping back down to 6500'

I have absolutely nothing to gain or lose in these conversations. A lot of it is just me being who I am and getting a rise out of the crowd. But the facts about my truck are no BS. I used to tow with a gasser and I know they have come a LONG way since. But I still contend that the wgt of the rotating mass in my 7.3 will carry it further up the hill before beginning to work than a gas eng.

Have a wonderful day. I really do enjoy the lively conversation.

Looking foward to a video. I always enjoy watching them. I used to get 18.5 around town with my Cummins Rams and 14~ with my gassers around town. Folks don't believe that either. Four 6% grades in an entire trip isn't quite what i had pictured. Still seems a bit easy on fuel for that much weight with any truck.

I believe you on your numbers hannibal but it is a pretty big stretch getting the mileage he is getting in those climbs. I will have to see some other kind of proof also. There's a difference between 6% for a few hundred yards and 6% for a few miles x4.

Yea!

When it 1st started I expected a REAL F350 hooked up to 80K, then either grenadeing the Transmission, or twisting the frame like a pretzel!!!

This is from "Ram Hemi owners - What octane do you use?"

Since we are on the subject, what kind of mpg do you all average while towing?

I'm hitting 10mpg towing my #6500 HTT.

87 around town, 89 or higher mix when towing. Alot of the time there is quite a bit of 87 in the tank so I will top off with 93 before leaving on a trip.

I would love to see if someone has done the hand calculations to find if there is a noticeable increase in MPG by running 89 octane.

For the person asking about MPG, I get about 7.5 to 9 depending on wind etc with the camper in my Sig. I did have one miracle trip coming back from coco beach with what must have been a tail wind the whole way where I just broke 10 mpg.

With my previous '93 Sunline low slung 6,000GVWR trailer I used to break 10 every now and then but that thing sat so low it was about even with my truck topper.

I know I have the largest truck equiped with a Hemi but I would be very suspect of anyone that claims consistant towing MPG in the double digits with a full size TT.


I average 8.5 MPG towing our 30' fifth wheel.

The 5.7L Hemi in my Power Wagon recommends 89 octane for normal driving and premium (high-octane) while towing:

"When pulling a heavy load or driving a fully loaded vehicle when the humidity is low or the temperature is high, use a premium (high-octane) unleaded fuel to help prevent spark knock."

Living in AZ, I tow in low humidity AND high temperatures. When I first purchased my Power Wagon I followed this and used 91 octane while towing until someone on another forum said it was not necessary and I was wasting money, so I tried towing with mid-grade 89. Well, the difference was quite noticeable. I had always been able to tow our fifth wheel on 260 on the grade to the top of the Mogollon Rim in 2nd gear. With mid-grade I was down into 1st gear with about a mile to go to reach the top. Back to premium for towing and the next trip (and subsequent ones) I was once again able to keep it in 2nd gear and maintain a higher speed to the top. This last spring the temperatures were a little cooler and with the price of fuel I again tried mid-grade and again I was down into 1st gear with about a mile to go to reach the top.

I didn't notice much difference in MPG, but there was a definite improvement in performance. I will be towing with premium fuel from now on.


Wow! Now I know why I changed from a gasser to Diesel!

Premium fuel to tow and only getting 7.5 to 9 mpg. I can't make a statement on the grade on 260 never been there, but 1st and second gear??

My Cummins is a daily driver 12 mpg towing (12K 5er), 14 city, and 20 mpg @ 65 on the open road.

One is 9 miles and one is 6 miles the others are considerably shorter. The cooling mist system helps & like I said after topping the rim there's about 60/70 miles of rolling hills that do not require more than about 10 psi boost or less.

Hannibal, those numbers are consistant with the Rams around here. Driving style and your right foot will make a world of difference. Ask roller183. He has a 2012 Ram 3500 dually and a 40' toyhauler, 3 slides and I think he told me 17K loaded and seems he told me he's getting 10+. Don't quote me but that is what I remember. He lives nearby and we'll probably be camping together Labor Day.

1 pull is 9 miles, 1 is 6 miles and the rest are considerably shorter. After topping the rim it's about 60/70 miles of rolling hills requiring 10 psi boost or less. My cooling mist helps also. roller183 has a 12 Ram dually and a BIG, 40', 3 slide toyhauler. He said about 17K loaded and he gets around 10+ as I remember. Ring him up and ask him. We met here and found out he lives nearby and probably will be going with me on Labor Day.

Hannibal. you #'s on your Cummins seem about right with someone not pounding on it and knowing how to drive. Driving style will get you good mpg's. But from what I have learned the Cummins seem to be better for fuel economy.

As for further proof all I can do is tell you to check out an Az topo map and check the elev along that trip. The first 110 miles have the 6% pulls. I start @ 1200' and topping the rim @ 8200' then down to 6500' Not hard to figure it out.
It's not a problem if you don't believe me, I have nothing to gain by bs'ing you now do I?
