After reading thru these and the 6.7 forums I'm convinced buying a new truck with the EPA choking emission is not worth it. You think in a generation ( of engines) or two it will be repealed or new systems to offset all the problems created by the EPA will be evolved? I can't see how we are being forced to choose between keeping our old trucks or less MPG and random shut downs to leave you stuck on the side of the road.

It almost seems to me the EPA wants to get everyone out of light and medium duty diesel trucks.

Anyway what do you think the long term plan is going to be? Ford has to be going nuts, I feel sorry for them.

 

I think that as time goes on the emissions will become refined to the point it will be like a gas motor.

I don't think it will ever be rolled back.

 

I think long term for the current EPA is to eliminate Diesel engines in passenger vehicles using these backdoor practices of making them too expensive to own. If you can get them to use more fuel than previous generations and choke them with emissions equipment you are killing them from two sides. Add accelerated CAFE ratings every couple years and I think it is pretty apparent what they are doing.

 

Loving the conspiracy theories.

I'm sure they said the same thing in the late '70s about powerful cars. Now a base-model V6 Mustang will trounce a '69 Shelby GT500. It was a laughable concept back then just as it is now.

My little 6-cylinder F150 just towed 12,000 lbs last weekend, gets 20 MPGs on the highway, and makes more power than my '08 F250 did. And interestingly enough, it tows better than my previous 6.8L V10-powered Excursion ever did.

And, more relevant to the thread at hand, the 6.7L Powerstroke engine is more than capable of delivering 20+ MPGs with reliability exceeding that of the old 7.3L engine. There are hiccups with every evolution of technology, and God knows the EPA doesn't make that easier, but they keep getting better and better.

 

The 6.7 runs way better with the emissions equipment intact than the previous 6.4 and 6.0. It's reliable, gets good mileage, and actually has power with it on.

 

I agree engine improvements happen over time but without question when there are outside factors (epa) there can be serious set backs that take several years to work out.

You comment about the 6.7 having better MPG and reliability of the 7.3 is interesting. I use my truck on off days to commute around town stop and go, everything I've read these new engines do not like that at all. I never worry that I'm going to loose power to a forced regen either. I realize the boards are full of horror stories and the huge majority of people who never have issues will never post their stories. Still the number of people posting issues with regards to these new EPA downgrades is too high IMHO.

I agree with the post the EPA want's to do anyway with light/medium truck diesels. However I don't think that goes far enough, if they had their way we'd all be living in caves with no electricity or running water.
