I read the "double digit" increase as not in miles per gallon but in percentage. They are stating that the fuel economy is at least 10% better than the previous engine in every test. I guess that's significant in that if you were getting 14 mpg before, you'll get at least 15.4 mpg now.
Now the question is, what engine did they run the benchmark against? Did they test against the 6.0 or something else? The article wasn't clear.

no problem, I just came uppon it surfing. I was wondering what the double digits were. I thought of percentage also, but 25mpg in a diesel would be sweet at least, but not practical.
Toyota could be a real player in the market, time will tell.

When Ford introduced the 6.0 in 2002 they also claimed a 10-12% increase in fuel economy over the 7.3 . After reflashing to what they are today I would guess that they are real close to the 7.3 in fuel economy (My dads 7.3 and my 6.0 get about the same MPG). So I would not believe that statement and I don't think they are talking about the ones used in the Ford trucks.... I would guess that it would be very difficult to increase fuel mileage and Power at the same time. That is unless they come up with some sort of on demand cylinder system where they could cut the fuel to each individual cylinders when the power is not needed. Kind of like they are doing in the Gassers.

Of course, Isuzu still develops and sells lots of other diesel engines.
