Very interesting to me...think I'm going to try it! Anyone else ever heard of this?

Yup I've heard of it. But not a 3 to 5 mpg increase. I've heard a lot of Ford guys that are unhappy with the new ultra low. But I didn't notice any difference in my truck. You'll also find a huge debate on the internet about the lubrication in ULS Diesel vs LS Diesel. I've seen reports showing the lubrication is the same, maybe better and it's just done a different way. I'm not about to get into that debate because I'm not educated enough on the subject. But I do see a small increase in milage when I use additives other than 2 stroke oil and the engine does quiet down.
As soon as I get my new fuel pump and 3 micron filter installed I want to try some of the B20 down the street and see how that runs. Supposedly better than ULS or ULS with 2 stoke.
