I just ran my "new to me" 2009 king ranch from Salt Lake City, Ut to Anaheim California. Most of the freeway limits have been raised to 80, so I ran 90 minus through towns and a bit in arizona. Averaged 12.5 MPG with 2 adults three kids and a pickup bed full of luggage/strollers/coolers. I think 12.5 (from fill ups not the lie o meter) at 90 MPH is pretty damn good. Plus this thing is fun as hell to drive.

 

It's been a long time since I've driven those open roads but ... it's my biased opinion ... driving this type of vehicle at those speeds (especially with a family) is crazy. Slow down and enjoy life.

 

I'm going to pretend that you didn't just infer I am crazy/stupid.
You know nothing about my situation. My rig. My driving abilities. Traffic for the trip, or the stretch of freeway. There's inherent risk to EVERYTHING we do every day. Some things are done to mitigate these risks. Driving my 2009 on the flat wide miles of view freeway is probably akin to the risk of driving a 1985 truck down a 50 mph highway. Let's keep the thread on topic.

 

I think all he was inferring is that a 7-8,000b truck will do serious damage at those speeds to itself and others around. No one is questioning ones driving expertise. Things just go from bad to incredibly worse at those speeds regardless of vehicle.

 

I'll tell you my Excursion handles just fine at 112mph. (removed limiter)

 

For the first couple years I had my V10 I was getting 9.5-10.5 mixed. After I did my plugs, cleaned my MAF, and replaced my PCV valve it went up to around 10.5-11.5 mixed...I know, huge difference right? But I also live in California and we have absolutely horrible gas here.

 

Any vehicle at any speed will DESTROY when it flies of the road. People, passengers, other cars. It happens. I see people fly by me all the time and think "man, what an *******" All I'm saying is that if I had felt like it was out of my abilities, or comfort level I wouldn't have done it. My family is my world and 20 minutes off a road trip isn't worth their lives. Id be an ******* to sit here and say risk doesn't increase with speed or a 8000 lb truck isn't dangerous as a projectile at 90. But do you really believe its any riskier than driving around with 4 kids in a camper shell on 1980's tech? Happened for years, and years and years.
Again, the point of the post and the thread is 12.5 MPG @ 90. Stay out of the rest of my business.

 

Ill bet it does! I know the King Ranch handled amazingly at 90. Felt like a honda, Well maybe not. LOL.

 

I'm sure there's a real world where you can get 12.5 mpg at 90 mph in a V10 F250, but it's not this one.

 

I stand by my earlier OPINION, driving these type of vehicles at those speeds is unsafe and reckless, putting your family inside while doing so is crazy. Sorry if you're offended.

 

Agreed, the thought of a tire blowout on a 4x4 vehicle at high speeds (especially the front) is enough to keep me from going much over the speed limit in my truck.

I've had my truck over 90 mph one time, and it was on a straight stretch of flat desert highway, with no one else within miles. It did cruise very nicely, but that could end very quickly if something went wrong. I would have to look, but I believe most E rated tires are only rated up to, and possible below, 90 mph anyway.

 

I was able to get 11.8 mpg on a 400 mile trip through the mountains at speeds up to 112 mph and long stretches of 80 mph+. I'm sure with a 5 speed trans in the later 3V motor and flatter ground then i'm used to it is very possible.

 

In my '08 v10 the best Ive gotten is 13.5 all highway. Mixed driving I usually get 11.5.

 

Just the cheapos that you buy. R rating is 106 mph, the Toyo ATs I just put on are S rated, 112 mph.

 

Nah, I'm with the rest of the group: that's simply a bad choice. "90- miles per hour" on public roads in a vehicle like that is just asking for carnage. And with a truck full of wife/kids...

I'm not here to preach, but when you defended your action 3 times while everyone else politely chided you...

Your defense is based on the idea that you have control if the situation. Which you don't/didn't. All you had was some influence.

And it's unreasonable to compare your action to 50mph on older technology.

Anyway, I get as low as 11.5mpg and up to about 13.5mpg with my V10 E350. Lots of highway miles. And maybe about 30-60minutes per day idling.
