I read on another board they didn't want to release the data for fear that folks would think that premium was required- so they already have them, just making us wait again!

 

So it'll run on both regular and premium and get even more power output with premium? It's like the 4.0 V6 I had in my FJ. It was recommended to run on premium to get the most out of the engine, but could run on regular too, but with diminished power. It's really not that much of a savings going regular over premium, especially if you're getting the engine's full potential and gas savings by using premium.

Going of average gas prices here in Dallas.

87 octane: $2.49 x 26 gal tank = $64.74

93 octane: $2.69 x 26 gal tank = $69.94


I'd pay an extra $5.20 to get even more power out of the engine, no doubt.

 

I will buy premium for towing heavy but see no reason to waste an extra $5 per tank just for every day driving where you wouldn't notice the extra increase in power anyway. Now if you drive it everyday like you stole it then it might be worth it to you

 

That's the beauty of having the option available. But like I was saying, if it is anything like how the V6 in my FJ was set up, using the premium fuel also meant you were getting better MPG's since you were getting the full potential of the engine as intended. It ran smoother, had better throttle response, and gave a little increase in the MPG's. I also ran premium exclusive because I lost some power by adding a 3" lift and 33" tires.

 

That will be a good question for me to ask on Saturday at the ride and drive event. I did a quick calculation based on your figures. If mpg went up from 20 mpg to 23 then you would save $2.69 per 26 gallons by running premium. I kinda doubt that it will go up 3mpg though for if it did then Ford would be using those numbers for their EPA figures as it would save them a fortune on fines due to CAFE

190lbs

 

I wonder if they are also going to be publishing E85 numbers...........if so, they will be even higher than premium but gas mileage will suck.

 

How the hell can the payload vary from as low as 1,030 pounds to as high as 2,860 pounds? is there really that much difference in the various trim levels?

 

Did anyone notice this on the 'specs' page?

I wonder which fuel they're basing the power numbers on, regular or premium?

 

Its been cyrstal clear: REGULAR

LMFAO

"The 3.5-liter EcoBoost truck engine delivers 365 horsepower at 5,000 rpm and best-in-class 420 lb.-ft. of torque at 2,500 rpm, with up to 90 percent of the peak torque available from 1,700 rpm to 5,000 rpm – all on regular fuel"

I'm so confused as to which engine to go with now. I do tow but nothing more than 5K. I really had my eyes on the 6.2L but the ECO sounds better everyday

 

If all you tow is 5k, a 5.0 will do that just fine. Heck - the 3.7 would probably do it too.

 

You right about that but I wouldnt go with neither of those engines, lol. It will have to be the ECO or the 6.2L

 

I think you might want to drive a 5.0 before you make that decision. I have a feeling it will make your 5.4 look sick.

Everyone around here is going goo-goo over the 6.2 and EB - and totally forgetting about the 5.0. The 5.0 is going to be the "bread and butter" engine for quite a while, and the 3.7 is going to be a fleet buyer's darling.

 

glc,

You are absolutely correct. See my post about today's test drives at TMS. The 5.0 was by far my favorite overall performer. It does make my 5.4 feel sick (not good "sick"). I had no doubt, as I have one in my Mustang. The 5.0 in the F-150 is much more 'mainstream' thatn in the Mustang. I really liked it and will entertain getting one in mid 2011. The EB was nice, but the 5.0 really impressed me.
