Real Cost of MPGs
I was just thinking that with all the talk of increased MPGs on the 2.7 vs the 3.5 or 5.0, that one really needs to look at more than just mileage numbers. For example the real cost of 1 mpg on 20k miles per year is $136.53 @ 4.10/gal
So if a 2.7 Eco is really 5 mpg better, then one is only looking at savings of $550/yr more to get a 5.0 over a 2.7. Is the sound of the v8 worth more than $550 per year to you???? Less if you drive less per year.
Something to think about.

I agree with your premise, but your math is wrong.
If you drive 20,000 miles per year divided by 15 miles per gallon, that is 1,333 gallons used. At your price of $4.10 it results in a total annual gasoline cost of $5466.67.
With a mpg of 20 miles per gallon, that results in the purchase of 1,000 gallons, or an annual cost of $4,100 per year.
That is a savings annually of $1366.67, not the cost you give of $550.
If you keep your truck for ten years, that is a total EXTRA cost of $13,666.70 in gasoline costs over the life of the truck. There is nothing wrong with the 5.0, but you must realize you are paying a lot for that V8 sound.
With that money you can get a lot of camper, bass boat, or steak dinners, etc., and enjoy your destination and not just the sound of the drive there.

At 20000 miles your using 800 gallons at 25mpgs.
At 20000 miles your using 833.33 gallons at 24 MPGs.
33.33 gallons @ 4.10 is $136.65 per year
Multiply that by 5 to get a 5 mpg difference (683.26). I did some estimating on the first post. I wanted to first see how much per mpg which is why I did it a little weird.
Regardless, it isn't worth it to get the 5.0 or at least makes it harder to justify unless you aren't driving much.

Using 2.55 a gallon which is what prices were, that's 1333 gallons used a year at 2.55 that's 3399 and vs. 2550 which is 849$ a year in savings. However I also don't really agree that the 5.0 gets 15 mpg average. I was getting 18-18.5 average before my tires and I am right around 17 mpg after adjusting for the speedometer.
I'll call it an even 17 mpg for simplicity and factoring in winter driving. Going by that and todays prices, that's 1176 gallons used and at 2.55 that's 3000 a year in gas. All in all that's a premium of 450$ difference. The V8 does come at a price but if someone hauls things or tows they won't want a 2.7, just depends on the application. If light to moderate driving is your application by all means the 2.7 was made for you.

That difference is magnified at 4.10 a gallon but those aren't the prices many folks are paying unless you live downtown Chicago. Before the Midwest refinery had its issue I filled up at 2.55 here in Wisco.

20,000 miles at 25 mpg is correctly 800 gallons, which would cost $3280.00 annually.
20,000 miles at 20 mpg is 1000 gallons, which would cost $4100 annually.
That is still a cost difference of $820 per year, or $8,200 over 10 years of ownership....assuming that gas prices didn't increase over the next ten years.
I have also done the math comparing a super-duty F250 with a 6.2 with a F150 Heavy Duty Payload Package 3.5 Ecoboost. According to Fuelly.com, the 6.2 F250 will get about 11 mpg. The F150 HD Payload 3.73 gears should be about 17 mpg. I plan to keep the new truck for 250,000 miles. Assume an average price of $3.00 per gallon.
250,000 miles with a 11mpg F250 = 22,717 gallons of fuel costing $68,181.92
250,000 miles with a 17 mpg F150 Heavy Duty Payload = 14706 gallons of fuel costing $44,117.65
Since the potential savings is $24,034.27 over the lifetime of the truck, guess which one I am ordering!

20,000 / 25 = 800
20,000 / 24 = 833.3
20,000 / 23 = 869.57
20,000 / 22 = 909.1
20,000 / 21 = 952.38
20,000 / 20 = 1,000.00
Though logically after counting for a unit mpg difference should yield a straight line relationship it doesn't.
The difference between gallons used between 25mpg and 20mpg is 200 gallons with a difference of 5mpg but the gallons used difference between 20mpg and 15mpg is 333.33 gallons.
