Ford finally releases specs for F-150 3.0L diesel

Average length of ownership for vehicles in the US is 71.4 months. So depending on who's figures you want to look at, that's a savings of $1,803 or $3,361 for your AVERAGE driver on that time-span. Now were the niche is, any higher than the 16,500 miles, that's where you can save some serious money.

So your claiming not a single person used anything but the weakest fuel that reported their mpg on Fuelly? ok? Does it not say anything about increased performance in that manual with premium fuel or differences in performance with different fuel grades? So according to you, that fuelly number just happens to coincide with the cheapest possible option. I don't believe that for a second....Cherry picking?

What I understand is that fuel mileage increases with better fuel, in-case you didn't know that.

Seriously?

As I said before I put over 200k on two 3.5L Ecoboost trucks(80k on my 4wd personal truck and 150k on a 2wd company truck) and the average between the both of them was 16 mpg just like fuelly states and I NEVER used anything other than regular octane. We also have over 200 parts delivery and sales trucks in our 500+ truck fleet at work and NONE of them have ever used premium or mid-grade fuel while averaging dang near what fuelly states.


So how many miles of experience do you have driving a 3.5L Ecoboost to say that the 16.2 mpg average on fuelly is with premium or mid-grade fuel?

Exactly! there is just not enough of a monetary benefit for most half ton truck owners for that they will have to give up. I don't think I am alone in saying that I would not give up 135 more horsepower and better performance for a monthly savings of less than half of what it takes me to fill up a 26 gallon fuel tank.

Although if you look at it in another way, I have paid thousands just to add 100 hp in my vehicles so paying an extra $250-350 a year for another 135 hp and 50 lb-ft is actually a dang good deal.

This is RV.net. Take that into consideration. Most half ton owners do nothing but commute and drive back and forth from the store. What possible reason does one have to need 135 more horsepower when it's costing them extra money (somewhere between $303 and $565 a year-a whole months truck payment for some is in that range)?

Now for performance, that is an opinion again. Good for you, you made it up the hill faster than me by a whole minute, but you also got 2-mpg at that time. That is not good performance in my mind.

As far as I'm concerned, you have no historical data on the subject. The one fact you reported was about a newly introduced truck in the very first year.

What does it matter what YOU did with your Chevy. We are not discussing what YOU do and are discussing what the AVERAGE truck buyer does which is follow the owners manual. Yeah, about that cherry picking......

I feel like I am watching Good Will Hunting. As long as the fuel differential remains in the 20 cent range the payback on the baby diesel will remain over 50k miles. This is longer than most hold onto their vehicles. There are good reasons to purchase the baby diesel option but saving cash is not one of them for those that don't keep their vehicles long term or put a lot of miles on them.

But the Ecoboost gas engine that were are talking aboutis a variable grade fuel engine and the owners manual recommends regular 87 octane for advertised power levels. Premium is only used if you want higher then advertised power level and performance.


So again, why are you using mid-grade fuel prices and not regular fuel prices?

Taking for granted the fact that people use that higher grade fuel to obtain those numbers on fuelly? Does Fuelly break that down? Give me the average mpg for the lowest/cheapest gasoline then and I'll plug that info in the spreadsheet.

Back with my Chevy, I got significantly lower fuel mileage when I put the cheapest stuff in. I only ran premium a couple of times, but never used the cheapest stuff if I could help it.

Again, using the correct fuel that the owners manual states our fuel savings for 2017 should look like this driving 10k annual miles

Same reason I didn't choose higher priced premium gasoline. The price is between the two and the performance/efficiency of the fuel should be between the two. I didn't even use the reformulated price, which I should have because almost every company has their own blend of additives, which falls into the reformulated category if I'm reading that correctly.

That's the beauty of this spreadsheet and formula. It takes the national average. these aren't my numbers. If your situation is more favorable or worse either direction, then you should personally take that into account when making your decision.
