I don't think anybody is trying to convince others to sell what they have and buy a 7.3. It's just another option and won't be right for everybody but will be right for some. I know I won't be buying one unless it's several years from now.
I absolutely intend on keeping my CTD until death do us part. The point I was trying to make is that 5 mpg (or possibly less towing a large fiver) will get old pretty quickly....
I get roughly 2 mpg less going from my 12 CTD to my 18 6.4 when towing. Where that comes into play is the smaller 32 gal tank. My Ram CTD had 35 gal
Not wanting to run either empty and figuring 5 gal for a cushion that gives me 315 miles for the CTD and 229 miles for the 6.4. Thats 86 miles a tank. Makes a big difference when you're in unfamiliar areas where fuel is uncertain. A few times we had 200 mile stretches with not knowing if some podunk town had gas. Gas Buddy wasn't always reliable.
On a 3200 mile trip this summer I found myself topping off the tank a 3/4 full a couple times just to be safe.
What are you pulling and exactly what mileage did you get with both trucks? Remember, that the 2013 and up CTD's run DEF which increased the fuel economy considerably. I get a solid 10-11 mpg pulling my 16k high profile fiver.
I top off my fuel tank a lot while towing as well; I find it much less stressful than worrying about making the next town. :)
A 5er and a TT. Both in the 9,000+ range. Regens on the 12 didn't help mpg's much. :(
The 12 CTD got anywhere between 10.5-12 mpg depending on conditions. Rarely saw 12 mpg. I always figures 10.5 for range purposes. The 6.4, 4.10 towing the 9500 lb TT gets 8.5-9 mpg.
I don't go slow and do push things when I can.
That's not bad for a gas truck; if I ever look to switch trucks I will definitely give the gas a hard look.ib516 wrote:
The diesel did downshift less though, and it was a better "tow rig" overall. I can imagine with the newest crop of diesels approaching and exceeding 1000 lbs-ft of tq that would only be even better.
^ This is the part the loyal gas engine folks don't like to acknowledge. Jump back 15-20 years to what is kind of the start of "modern" drivetrains.
Big fuel injected gassers, high pressure injected diesels, more than 4 cogs in a transmission....
Gas engines were HP in the mid-high 300s and TQ in the high 3s, low 400s.
Diesels were in the 300hp range and 500-600ft lbs.
Gas engines are now low to mid 400s HP and low to mid 400s TQ.
Diesels are 400-500hp and 900-1000tq.
The diesels have almost doubled in what counts for towing, torque, and the gas engines have made great strides in efficiency and notable gains, but nothing earth shattering.blofgren wrote:

That is not true either because they are also using Cummins diesel CNG engines as well in their bigger trucks. Cummins Wesport is also working on a CNG version of the ISV 5.0L V8 because the ISB 6.7L CNG engine is too long to fit into there van trucks.
CNG has limitations as a long distance alternative to diesel. That is why it has not taken off outside and inside NA
This is false. Studies from Cummins and others in the industry show that there is only a 5-10% drop in fuel economy from a diesel powered truck to CNG diesel powered truck. Since the CNG cost much less here thanks to our over abundance of it in the US, the cost per mile is much lower for a CNG powered diesel. Not only that, but since it burns much leaner, there is no need for a DPF or SCR system. The 160 & 175 DGE tanks that my company currently builds allows the truck to go between 800-1,000 miles between fillups.
What they do outside of NA regarding CNG is really not my concern, but most of the world does not have the amount of natural gas the US does so this may be a big reason why it has not taken off in other places. You also might be thinking of gas engine CNG conversion which is not the same as a diesel engine CNG conversion.timmy88 wrote:

Are you asking about the link in the opening post? It works fine for me gut here it is for you to copy and paste: https://www.youtube.com/watch?v=4HiR9dxvGLY&feature=youtu.be- who has the link working ? I can't open it I don't know what it's about

It was rumored that the 7.3 would be mod friendly, but I didn't expect the better part of 200hp with mostly bolt on parts.
That's seriously cool!
Pushrod engines aren't dead! And they're not 4' wide like OHC motors.
Yeah, that is a short list of parts for an additional 200hp. Usually it takes forced induction or at least $10k in parts to get that kind of bump out of an N/A engine.
I agree. The hp. gain is over 39% and considering that it already has 430 hp. that's a lot.
I still say pretty poor overall. Emissions will be your major concern , better pedformance engines around. This was not designed as a performNce engine, but a moderate heavy duty commercial engineblofgren wrote:

I got 7-9 mpg towing a 12,000# 37' triple slide 5er with my 6.4L Hemi.
With the same trailer, a 2007 5.9L Cummins got 9-11 mpg. The fuel saved by the better mpg the diesel got was about the same as the increased cost of the diesel fuel, so the overall cost was about the same. The diesel did downshift less though, and it was a better "tow rig" overall. I can imagine with the newest crop of diesels approaching and exceeding 1000 lbs-ft of tq that would only be even better.
The only time I got 5 mpg when towing was with my 2001 Dodge 2500 with a 360 cu.in and 4.10s pulling a 33' bumper pull that weighed about 9k. That old Dodge drank unleaded at a rate of between 4 and 7 mpg depending on how hard it was working. To it's credit, it never gave me any trouble even when I worked it very hard pulling in the mountains at about 200# over it's max tow rating and full of payload, likely over my GCWR.blofgren wrote:

This non sense started by someone who thinks their truck is the best by the best as usual attacking gas powered trucks. I thought he was going to ignore these Ike towing tests but I guess not.
There's a clear movement and a market for gas powered trucks in the medium duty market. One example the UPS trucks in my area appear to be all gas powered now.
Uh, Fish you may want to look back at your earlier posts to refresh your memory as to who started the nonsense....
I never said my truck is the best; I simply stated the major downside of any gas engine when pulling which is undeniable. If you look back through my posts over time, you will clearly see that I'm a big fan of the gas Ford engines; we have many of them at my work including V10's and the 6.2L and they have all been great workhorses. I fully expect the 7.3L to be just that as well and have stated that many times.
The 7.3L engine performed much better than expected and I totally commend it for that. If I was buying a new truck today, the 7.3L Ford would definitely be on my short list. Now back to your regularly scheduled agenda.....:R
I wasn't referring to you... :W
