V-10 vs 6.0 Diesel milage

[rdbpower]

We have kept records at work and here are the results. We average 12,000 miles a year. The trucks are 06 4x4 crew cab chassis cabs, with service bodies. The diesel has 4.10 and the v-10 has 4.30. For the diesel we have 12k miles at 9.83 mpg=1220 gallons at 4.24 gallon=5175$ For the v-10 we have 12k miles at 7.68 mpg at 3.65 gallon=5685$ So the diesel is 500 dollars a year cheaper in fuel. But with the diesel costing 6000 more upfront it only takes 12 years for the diesel to break even. I didn't even factor in way more oil,filters etc. Then the big kicker is the v10 needed a new battery. The diesels have been nothing but headaches. As a side note the trucks are towing a skidsteer trailer with a cat 247 so we weight about 24k pounds.

Yeah, well this is a diesel web site and all, but......there are alot more problems associated with a diesel engine than a gasser, and you know it. Bad fuel, plugged fuel filters, leaking gaskets, plugged soot collectors, expensive oil changes, ad nosium. Look, I am a former 7.3 owner and loved that truck for what it did for me, but, since Ford did away with that engine, I'm a die-hard V-10 fan for all of the reasons I just listed. This V-10 is one super engine and combined with the TorqueShift tranny, is as good as it gets IMHO. If it didn't perform, I would say so, and do something different. I am here to tell you all, if you are looking to switch from diesel to gas, don't overlook the Ford V-10 as it is a Boss setup.

Let's also not forget the 6.4L gets worse fuel mileage than the 6.0. You can also add on new emissions crap to the 6.4 (DPF) that will need replaced down the road. The comparison is hardly close.

This is the kind of post that I've been looking for for a while, some actual data instead of moronic hearsay that is commonplace on these forums.

It's unfortunate that the diesel's high purchase price negates the fuel savings. And that's before discounting future cash flows (ie you could invest the 7k and make ~7% on your money for the time you owned the vehicle)

I now have about 1,500 miles on my truck, I am getting 10 mpg city and 13 mpg expressway. With my previous truck (see signature) I was getting 10 mpg city and 17 mpg expressway.

I got 1 mpg more when I added a drop-in K&N air filter. Getting 11 around town.
