OK I have done endess reading on everything from the tundra to F150s to F250s. I know I want a full size rig with a 6.5 bed. With that as much as I love the new tundras, I dont want the access cab in order to get a larger bed. What I'm left with is looking at the supercrew f150 with the 6.5 bed. I'm also looking at the f250 crew cab as well. Personally I love the f250 CC but somewhat afraid of the 6.0 psd. I've read everything about them and am fairly certain I could probably bulletproof it and be fine.... but what is fine. Is fine that I spend much more on diesel fuel compared to gas and I would be just as happy with a gasser. Probably. If a f150 supercrew long bed with 35s and an f250 cc with 35s were both compared for gas mileage what would it be. This is where I am... the comparisons of both and which to go with. Help

 

In before the 6.0 haters get here. Also in before the obligatory uninformed get a 7.3 comment.

Are you wanting to compare mileage between a diesel super duty and a gas half ton?

 

What do you intend to use the truck for?

 

I'm not a 6.0 hater at all. I would buy one tomorrow and spend the money up front to take care of the known issues. My thing is if I pay the price for the truck, pay the money to get it corrected, then still only pull about 15-16mpg in the truck... is getting the diesel still worth it? I can look at a 2009 supercrew long bed 5.4L..... raise it up on 35s and probably get 14-15mpg. I can look at a 2007 f250 with a 5.4L put a 4" lift in it on 35s and probably get 14 as well. I think I'm mostly looking for direction. Is the 5.4L in the 250 just a horrible dog to even turn the 35s? Is these numbers somewhat accurate?

 

The new Eco-boost F150 should not be underestimated, its a pretty strong truck. Well Expecting a mild lift with 35's id say almost the same mileage. Diesels do not make good grocery getters, The 6.0 was made to work! If you are using it as a daily driver with less than a 10-12 mile one way commute go gas hands down as that will just get the truck to operating temp. Driving diesels short distances is never a good idea. The maintenance cost is another thing to factor in as well.

 

Only place you will get 14 mpg with a 5.4, 4" lift and 35s is the highway. I only got 10-11 city with mine

 

14-15 mpg on a Super Duty gasser, let alone a lifted one? Unlikely. Owned both a 5.4 and now V10. Average was/is 11.5-12 and 8-10 respectively, mixed, stock suspension and tires. F150 5.4 got me 14-15, again unmodified. You'll definitely get better mpg with a 6.0 but may have to sacrifice for and older truck with more miles depending on budget. Unless you're driving 15k+ a year mpg is a moot point between gas and diesel of similar years. Different purchase prices, needed upgrades on the diesel, and other odds and ends will knock out any mpg gains if the mileage is less that ~12-15k. If you want the diesel for power and whatnot than just get it. Cost justifications just aren't there in my opinion unless you really put the miles on or buy an older 100,000+ mile truck to bring the purchase price down.

 

I drove mine to the grocery store which is 2 miles away. I also drive it to work which is 5 miles away every day. Then it sits all day while I drive a company vehicle and then I drive it home 5 miles. No problems. The truck is warmed up by the time I pull into the parking lot.

 

only thing i use my trucks for are basically family expedition vehicles, camping, family hauler, daily driver, etc, etc. I hold vehicles way beyond what others do. My current 4runner is now clocking 310,000. I find myself researching to prepare myself for a new truck wife.. which is why the endless searching i'm doing now

 

hmmmm... thanks for the opinion guys. My work commute is about 20miles each way... all highway. Here's what i want.. I want a full size crew cab with a 6.5 bed with a mild lift or leveling kit and 35s. With that scenario I looked at everything. The 6.0,6.4, 5.4 and v10 is what I looked at. I was hoping in the setup I was looking for I was trying to get 14mpg. I was thinking a diesel might land me 2-3mpg more maybe. Guess my figures were off

 

Yea with the combo you'd like to have, 14mpg just doesn't seem likely with a gas truck. You'll have one person saying they get 16mpg with a V10. Only with a regular cab 2wd. Just make sure to get what you want. I like newer trucks but with my budget a diesel is just out of reach.

 

The only thing really keeping the mileage low is the lift and 35's. I have a 7.3 Ex that gets 19.6 mpg hand calculated on the highway, Mixed is about 15,16, I take it easy and don't have a heavy foot. You can find great deals on 6.0's right now needing minor work. The 6.0 will last, the issues really start to happen when people start adding tuners, towing heavy often, and not maintaining the cooling system. In my area theres a 2005 F250 Lairat 4x4 CC 6.0 for 7,500.00. The owner says there's white smoke coming from the tailpipe and does not want to mess with it. A bulletproof will run about 5,000.00 so after everything you could wind up getting the truck for less than KBB with the upgrades!

 

No! Lol

With a crew cab, 4wd, and the big heavy tires you might hit 14 cruising on flat highway at 55. Real world driving you will be 10-11 and probably hit single digits in the winter with winter blend gas, idling, 4wd use etc.

The 5.4 will feel like a dog with the bigger tires unless you find one with a 410 or 430 rear.

The f150 is going to weigh WAY less and get better mileage. If using as a commuter car and people hauler it probably makes more sense...

Btw this is coming from a 5.4 fan. But my lil regular cab stripper model is at a lifetime average of 13.5 mpg. The crew cab, bigger tires, and an auto trans will suck 2-3 mpg off that easy

 

In my opinion unless you are towing heavy go for the gas motor, with 35s your can regear to put you in a good rpm power band, you wont get as good of mileage as a diesel but the offset in fuel cost and maintanence you should be pretty close in per mile cost. For me just the black smoke and stench when you start the diesel in the garage is enough for me to stay away from them. Sorry CMK..

 

If the cost of maintenance doesn't effect you then Id say go 6.0. Keep in mind that oil changes with quality oil and filter is about 125.00. Fuel filters are not cheap either and The only correct filters are motorcraft. I have seen issues caused by aftermarket oil filters and they are never cheap fixes. I say go test drive both and you get the truck you want! don't let the 6.0 scare you, Its really a great motor. The 06-07 models really had most of the bugs worked out by then.
