Unless you drive 50K+/year AND tow/haul heavy loads, anyone shopping for a new truck should consider a Ford Super Duty with the 7.3L gas and 10 speed transmission.


So what are the numbers? Calculate initial cost, total fuel costs, DEF costs, maintenance, taxes, registration, interest rates, and resale trade in after 100k miles. I did, and came out ahead with my Ram 2500 Cummins over the 6.4L 2500 using both 87 octane and the higher 89 octane that was recommended. The total cost on the 5.7L was lower though.

So what are your numbers? I don't know about you, but I would gladly pay for a more powerful engine upgrade if it only cost less than $1,500 over the course of 5 years/100k. Many pay more than that on engine upgrades in half tons.

Yes, that must be the excuse for the disparity. All Ford F250 owners must use their trucks differently than Ram and GM owners...... And F250 V10 owners must being towing all the time to get this kind of fuel mileage.


Misleading data outputs...are misleading regardless of it makes you happy.

For similarly outfitted trucks, it's silly to expect a big difference.

Yes, some manufacturers have links to particular industries that have different uses for the trucks, so there can be different usage patterns by brand.

Incomplete at best. You don't have insurance, repairs, depreciation, cost of money, ... just to name a few. You don't even accurately reflect the $10,000.00+ increase in initial cost of the diesel vs. gas to start with.

That may be but it does show what I've always known and that is diesel fuel and DEF cost the same or less than its gasser counterpart. The anti diesel folks always squawk about how much diesel fuel is but never figure in the lower mileage of gas. I also think he is being generous with the oil changes, I pay $101 for an oil change and tire rotation at our local GM dealer.

Can you find some data on Ford and GM's 2.7 turbo engines? I have heard some incredible claims on the Ford and would like to see some hard data on that. I have heard so little on the Chevy it would be interesting to see what it is actually doing. If there is any being posted.

Repairs are null in 100k miles since all diesels on the market today have a 100k mile warranty from the factory. Insurance is within $5. Depreciation is factored in on resale. Cost of money is only a factor IF you paid cash and where going to invest that money. Most borrow the money. What else you got?

Also, as I have said in the past when I have posted this spreadsheet. These numbers are based on fuel cost, resale values, and so on in my region. Not everyone will be the same or can attain a 1.95% interest rate like I did. Hence the reason why I tell people to do the math for themselves and they will see that upfront cost $8k starts to decrease dramatically after everything is calculated. In fact, you pay way more than the upfront cost going from the 5.7L to the 6.4L gas in the long run due to higher maintenance costs yet no one talks about "recouping" their money there. Why is it only brought up on the diesel? It is an engine upgrade just like the diesel is it not?

That being said, when you hook up a trailer to them, they all get about 10-11 mpg

Not misleading. The data is there, you are just too lazy to dig it out which is not the fault of the website. What better information do you have to throw dirt on another? That is like someone who complains yet does not have anything better.

A vast majority of the people posting ion this site are using these vehicles as personal daily drivers, not fleet trucks.

It seems the Ford 2.7L is getting about 2 mpg better than the 3.5L Ecoboost and 5.0L.

The 2.7L in the GM seems to only be about 1 mpg better than the 5.3L.
