Eco Boost vs V8

[jejeosborne]

We've had a few guys around here take the ecoboost back for the 5.0 coyote motor. They say the mileage difference isnt enough to justify the extra money of the turbo v6. Also, they are having issues with turbochargers and exhaust temp issues when towing. One guy has been pulling nonstop since the truck was new and is having blow by issues already.(60000 miles) Remember, your working that little motor allot harder to get the same power of the v8. The three trucks that were returned to the dealership in favor of the v8 model were running okay, just the owners werent happy.

Interesting. I didn't realize you could return a truck.

I agree that the mileage difference isn't noticeable but it sure is between the ecoboost and the 6.2 liter.

What issues are they reporting with the turbos?

There is no comparison in towing performance between the 5.0 and the ecoboost.

So, I have a question for all those hand calculating their mileage to confirm the computer display. How accurate is the odometer that this is all based on? My truck's speedometer and odometer were off 10 percent from the factory (and not in my favor from a warranty standpoint). I lifted the truck and went from 245/75 tires to 33" tires, and the speedometer is now dead accurate.

All the vehicles I have owned, about 25, with most being Ford were dead on. Never more than .2 mpg off. The exception was my one Dodge. It was off not in my favor by more than 2 mpg. I have also had 4 GM'S, Toyota, Nissan, Honda, BMW, ect that were all very accurate.

I think (or thought) most vehicles were pretty accurate now-a-days. My '01 Ford Ranger and '02 Ford Crown Vic seem to be accurate. But that certainly wasn't the case many, many years ago. When I started in law enforcement (1964), we had all Fords and the shop put a sticker on the dash of each one showing true speed at different speedometer readings. I don't remember for sure when they quit using those stickers, but it was late '60s or early '70s.

It's a little known fact that MOST manufacturers will undersized tires on trucks to boost towing capacity while slightly sacrificing the odometer numbers.

Ie; 4.10 axle requires 32" tires to get an accurate
speedo so they put 31" tires on to boost tow
numbers and still be close to accurate.

Don't believe me...take a new truck for a ride with a hand held GPS unit; or even better get a police officer buddy to clock you on their radar.

Mile markers along the highway are a sure and accurate test. Mine have always been dead nuts on with factory tires.

I'm not sure exactly how accurate that is, but it's close enough for me, and that's what I've normally used myself.

Vw's are notoriously off by 10kmh or so. Our explorer was off by 12Kmh, but the odometer was bang on....

I think the MPG read out in the F-150 is more accurate than doing it buy hand. I have checked it a couple of times and it has been within .1. I think the difference is I may not be getting the tank filled to the same level every time so the hand calculating is less accurate.

I the speedo is accurate.

When I got a GPS, I found that there was a 3 MPH difference between the speedometer and the GPS on my 2007 Jeep Liberty. Then I noticed the same thing on 2 rental cars, and on my '96 Silverado. I thought maybe it was the GPS, but then I ran through one of those speed checker/warning things, where they have a radar gun setup with a sign that says "Speed limit XX Your Speed YY". Matched the GPS exactly. Since then,and as late as today, I have been through a few more of them, and the speed always agrees with the GPS. Makes me wonder if there is some kind of deliberate error built in to the speedometers to fudge the mileage ratings, or maybe by secret government mandate to slow people down a couple MPH. Same error on 4 different vehicles seems a little to much of a coincidence. IF the GPS is accurate, all those vehicles read 3 MPH slow.
