So you want to take the 6.4 from 11 mpg
to 18 mpg
? When the same efforts have shown that you can take a 7.3 from 20 to 27 mpg
Not many 6.4's on the road now, nor will there be when they trash it.
Same goes for 6.0's.
Dare I say there are millions of 7.3's still
running, since they've been on the road for over 14 years now?
There's a reason I still drive a diesel. It's becaue I can, and do, burn 'Free' fuel like veggie oil or WMO. Can't do that with any gas car I know of, regardless of it's mpg
It'd be neat to do a study of actually how many of each type of diesel is titled for road operation. 7.3's, 6.0, 6.4, 12v, 24v, Duramax's.
Then target the one that has the most on the road today.
Or just use your truck, Dave, as a perfect example. Why not? It doesn't matter how 'one off' it is. And take what you've done and apply it to a D-max, 24v, 6.0, etc to show 'common' results.
