If the average american drives 12k per year that is 12.5 years of engine life before rebuild- sounds good to me as I drive less than 10,000 a year. And he didn't specify it that was driving it hard, heavy towing, etc or the driving that most do with trucks these days- commute to work, grocery shopping, etc

I didn't ask what the spark plug change interval was- I am out of practice on changing plugs, I haven't changed any since 05 when I went to the diesel.

 

Just left and man it was a blast
3.7 felt a little slower than my 4.6
5.0 was great on the drastic
6.2 was better than 5.0 but it isn't available in xlt
Eco boost was the fastest thing there and I got to pull one of the big trailers and the guy told me to get on it
0-65 just like that couldn't even feel the trailer
Overall fun
In the end track dried up and we did head to head racing

 

That should say dragstrip
Sorry I am on my phone

 

Great writeups! Did they let you Test drive the Raptor supercrew there? Looks like they had a Silver one.

 

No just got to look

 

Only 150k miles? If only the EcoBoost was designed to last like the 6.2. Oh wait... The 6.2 is also designed for 150k miles / 10 years.

Good catch

 

I normally don't play words in private life, but unfortunately in my professional life I have no choice since the lawyers will do it to get their scumbags off. Granted I know what we are being told is second hand, but the quote given was that the engine will last 150k miles, not that the engine needed to be rebuilt at 150k. There is a huge difference. The engineer could have just as easily said the engine will last 100k.

I have taken two Ford vehicles over 100k in a ten year period (my normal trade time). Neither went over 150k. I bought both new and I didn't have any major problems with either. I seriously doubt Ford is going to intentionally put out a vehicle that has such a short life expectancy and harm their reputation.

 

I am sure that "last 150k miles" would mean before an overhaul. What in the world could happen to it that it couldn't be overhauled? A cracked block? and Ford sure doesn't design the aluminum blocks to automatically crack at 150k miles.

I would even think that the turbo's could be rebuilt- If they can withstand the heat then what would wear out but the bearings?

Same thing on the 6.2 150k miles /10 years durability? What does that mean? How can you say a engine will last 10 years unless you mean that is based on the average driver and if so you should say so.

Valvoline says that the average gas engine is good for 125,000 miles before an overhaul and that diesels last 3 x longer



I also found this:


FORD which has previously designed cars to have 10 year or 150,000 miles life has reduced the mileage life expectation to "beyond 100,000 miles" on vehicles that are operated on SAE 5W-20 Motor Oil.

HONDA only claims "useful life" as 7-years or 70,000 miles in EPA certifications for their CIVIC which uses SAE 5W-20 Motor Oil, while the previous model that utilized SAE 5W-30 Motor Oil was certified for 10 year or 100,000 mile durability . Comes from here http://www.synlube.com/viscosit.htm

After reading more here http://www.eng-tips.com/viewthread.c...=166636&page=3 it appears that Ford wants the EPA to think that the engines will be out of service by then so that they don't have to worry about the pollution controls failing


We need an automotive engineer to step in here to explain exactly what these numbers mean

 

In any event, 10years and 150K are very respectable. There are many cars out there that have lasted much longer, as I'm sure the modern engines will. I wonder what life expectancy they placed on the 4.6 originally? There are tons of them out there with 200K + hard miles that are still going strong.

 

Trust me, my point of my post was not to bash our engines -

I was just surprised to see that kind of information in print - I've never seen a life expectancy for any engine in print before.

I guess I am used to my diesels where 150K is just broken in.

I am hoping that my '09 will last longer than that, and I think it will with diligent care and maintenance. This is the only gas engine I own (out of 4).

Just seemed weird to me to see that life expectancy.

 

I believe all manufacturers benchmark the 150K durability mark. The question is how do they come about it. Towing uphill for hours on end or driving down the road from coast to coast at a steady speed. Or, running back and forth 3 or 4 miles at a time with a cold engine. I imagine its all of the above.

From my experience new engines just last longer than they used to. Back in the 60s and 70's you were lucky to see 100K. Now, its nothing. Oil is better, engines are built better and FI has helped. People probably drive further now than ever before much quicker than they used to.

I have mostly owned Fords and Chevrolets in my lifetime and they both seem to hold up long term about the same. I dont beat on them but I use them but I try to keep up on oil changes and what not. Both companies need to figure out how to make an alternator lasts(especially GM), make water pumps last, make fuel pumps last, make AC compressors last. Its been my experience a bunch of stuff like that gives up way before the engines ever get close to the end of their lives. Most of the time I end up with a car or truck falling apart around the engine. That has been the case with my old GMC truck right now.

 

What about the electric power steering? Any noticeable differences?

 

Very responsive. Reminded me of my first front wheel drive car- as soon as you move the steering wheel the truck moved- None of that loosey- goosey free play crap.

Also no "death wobble" like my F250 has. I liked it.

 

I don't know on the EPAS. I love it on my Mustang, but not on other vehicles I have. I really only noticed a big difference from my F-150 on a couple of the several I drove yesterday. The steering on the 5.0 felt really "light" to me. The others seemed to be very similar to mine.
