I was wondering the same thing! i have a 5.4 and i love it, it makes no sense to me why the 5.4 is a target for all Super Duty haters and Diesel guys.Hey remember it's a SUPER DUTY!!! no matter the engine.

I think it's because it is the smallest motor, people love to pick on the smallest ones......

It's a Ford That's all that matters

If it got better mpg's I'd say I like it. Looking back I would have looked for the V10 for more power with similar mpgs. I think that is the major downfall for the 5.4. Less power and same mpgs as a larger more powerful motor.

I don't buy into the same mpg theory either. I know several guys with 08+ V10 Super Duty trucks as well as several with the V8....the V10 guys are all stating mpg readings of 10-12 mpg versus the 14-16 mpg from the 5.4L guys. I think the equal mpg rule is something invented on the internet and not to be expected in real life.

I'm thinking the 5.4 has a better chance of hitting 350k miles then the 6.0's have,,,LOL !
and thats Just driving in Genral !

My Nephew works at a Subaru dealership,,,back when the "Cash For Clunkers" was around,,,they would get in a "Supposed Clunker" and drain the liquids out of the engine,,Dump in this Like "Liquid Glass" (someone here must know the product) stuff,,and run the engines till they Quit,,,most engines would die 3-4 mins after started,,,Now he saw many engine's Go to there Dreadfull Demise,,,,,He told me the toughest engine he did was a 5.4 Ford Van,,,the engine ran for 15 minutes,,,making some Horrid Noise's,,but died mostly because of over Heating,,,,,,What a waste of Good Parts !!! It's an OBAMANATION!!

But Built Ford Tough !!

I get 11.5-12.5mpg all the time, hand calculated with mixed driving. My best all highway was 13.5. Maybe a reg cab 2x4 could get 15 or 16 but I'll never see that. I'm sure the V10 would be worse, but not by much.

Not beat a dead horse, but my '04 V10 CC 4x4's mileage on my daily commute (50% town and highway) is about 11.5 winter and 12.9 summer due to the different gas blends. On freeway only it's done a rock steady 15.4 with no problems and once it got 16.2 going from Reno, Nevada to Willits, California so good mileage is possible with a V10. But it's still no Prius when it comes to mileage and I never expected it to be. Anyone who expects a 7,000 lb truck to do everything well (MPG, towing, hauling and reliability) is dreaming. Although the new 6.7's we have at work seem to be pretty good so far, but I can buy a hell of a lot of gas for what they cost!

That is a question that have to be verified by the "door sticker" and individual part numbers.

I know we all consult our door sticker before carefully loading our truck for the final word in safety, but I wasn't always that way. When I was just out of high school, I worked for a contractor and at the end of the day, me and another stellar employee had to haul 1 1/2 tons of 50 lb bags of lime to the bosses in laws' house in the bosses 1977 Toyota pickup. We had two choices, do the sensible thing and make three trips (and be late for beer time) or see if we could make it in two trips and only be a little late. Once we got half the lime bags on there, we decided it barely sagged and put a few more on, then a few more, and finally decided we might make it in one trip. We did and two things happened, the rear axle was lying on the frame and the bosses in-laws ratted us out, PO'ing the boss later. But we made it and didn't do any permanent damage to the truck. I can't even imagine how much weight it would take to make a SuperDuty sag like that poor Toyota, but I would imagine it would do it all the same.

I know exactly what you are talking about.

Some years ago, Toyota sold a truck chassis to RV makers to build motor homes on them.. and of course, everyone overloaded them.

End result: a massive / expensive recall that replaced every rear axle out of nearly the whole fleet sold, and Toyota got out of the business.

Then I can tell you stories of the stretched Toyota Tundra frames...

You have to understand... I take tow ratings from the factory, and typically DERATE them 20 to 30% to get a number I am happy with.

But that is a different operating philosophy.

You do not need to do that with a Super Duty. Aside from the 4R100 transmission in the earlier trucks (which need to be kept cool for longevity) these trucks will easily and safely pull what the factory rates them to pull.

"I take tow ratings from the factory, and typically DERATE them 20 to 30% to get a number I am happy with"???? gearloose1 I would possibly take your stance if I were looking at a Chevy or a Dodge however I feel Ford underrate their trucks with plenty of room to spare my truck is living proof of that I'm over my maxim most times by 2000 1500 pounds daily delivering material across upstate New York and Vermont and Massachusetts most drives are over 230 miles round-trip. One other quick thing someone mentioned the engines are medium duty you're kidding right? My last F1 50 with 5.4 hauling well above its maximum drove for four years with 187,000 miles without one problem I don't think anyone gives a 5.4 enough credit, remember these are not speculations I tell you my real life experience not watercooler talk take care

Thank you for that radium. I really get weary of these guys who have never given the 5.4L a chance slamming them.

The bit about weak frames and puny brakes is especially silly.
