V10 and milage

depark · 02-12-2013, 07:30 PM

To all the V10 guru's out there let me pose this question to you all. If a person has a 2013 E350 RB V10 with 4.10 gears and 4x4 with a weight of 8000 lbs. Add a Livewire TS, AFE intake from 5star tuning and an after cat exhaust. The fuel tank is 30 gallons. Would it be realistic to get 10-12 mpg City and 14-16 mpg Hwy? The van is going to be similar to my 2006 E250 and those are the mileage numbers that I'm getting with the 5.4l. I am trying to figure out if the V10 is the way to go. I know that the power is the biggest benefit but can I afford to use it as my daily driver is the question.
Thanks Everyone
Darryl

My van is a '12 E350 EB with the SMB & QuadVan conversion. It has the V10 / 4.10 and weighs 8,600 lbs empty. Highway mileage is consistently 11.5 mpg and city mileage is about 9.5.

When I first got my van (with 105,000 miles on it) I average 14.5 hwy, usually at 70-72 MPH. It had 3.73 gears.

Now its a dually with 4.56 gears and I keep the roof rack on permanently, I typically get about 11-12 mostly highway. Van weighs a little under 8,000 empty. I'm averaging 10 MPG commuting in Portland traffic right now, but to make the commute less dreadful I'm driving it pretty hard.

My morning commute is 15-20 minutes, but the evening commute is 35+. Even with the V10s poor fuel economy, it still doesn't pan out to get a new commuter car. Not even a hybrid. I could probably save $150 month with a small beater commuter car, but missing a couple few hours of work due to a breakdown would wipe that right out, not to mention the repair costs. Plus having the van at work means I can simply step out the office and drive straight to the mountain, since I keep my ski gear (and boating gear) ready to go in the back of the van at all times, and if I tire myself out playing I can just sleep in bed in the back.

One thing important to note is the heavier the load, the closer the fuel economy between the two motors becomes. When I towed my Weekend Warrior trailer (41'*11,000 pounds) with my dad's 5.4L E350 it averaged 6 MPG empty. With my van I averaged 8 whether it empty or loaded with 7,000 pounds.

I've got 1,500 miles on my 2013 RB E-350 with V10, 4x4 & 4.1 rear differential. So far I'm averaging around 9-10 mpg with mostly highway driving. I'm hoping that after everything breaks in the mileage will improve. It can't get much worse.

Not sure what the van weighs but I'm going to get it weighed when I get some free time.

2007 E350 4X4 with the V10 and 4.56 gears - consistently gets 12 mpg whether I'm hauling down the freeway at 75 or ambling down a dirt road at 35. Funny thing is, the rig came with 3.73 gears; I regeared to get the engine rpms up and stop the constant shifting in and out of overdrive. It got 12 mpg with the 3.73 gears and I expected that would drop with the 4.56 but mileage has stayed exactly the same.

I have a v10 EB with 4.10 gears and 4x4. I usually weigh in around 8k lbs as well. My aerodynamics aren't so great (plenty of lift) and I'm running 33" BFG RTs. 12 MPG is about the best I can get on the highway with cruise set at 55 mph. OTOH I've done no worse than 9 MPG towing a half loaded dual axle car hauler. I really don't want to know what the numbers are on a soft trail (I carry plenty of spare fuel and usually use most of it).

Around town I do worse as well, but really, it's not as much worse as I do with a turbocharged 5 cylinder wagon (which does better in both scenarios, I just don't see as big of a spread).

To me your aspirations sound overly optimistic. However the right tires and not too much lift should help some. I'm less convinced of the tuning.

Thanks for all your posts! It is good food for thought. It seams to be very consistant between everyones xperience. It's greatly apprciated. Now for the big decision, Power over Milage.

Cheers

You might want to consider headers. See more info under my BillPa1.

I get 11 MPG everywhere. Regardless of load/speed/terrain.

FWIW, if you're going 4x4, SMB-W only converts the V-10.
