3rd tank: (working on that now)

The 2nd tank surprised me because I spent 150 miles towing my 5x8 with ATV through the mountains of western Maryland. I was using the Towing feature; the truck had noticeably different shift points and it was obvious that the extra weight was there. I expected this tank to yield much lower MPG due to the hauling, but it came out .2 higher.

I used to run a fuel catalyst in my 2 stroke 500cc atv all the time and found them to keep my fuel always fresher and never had any fuel problems while running it. They look like metal "mentos" that you drop in your tank.
I would not be surprised if there was some science here at work with this moon dust.
Making fuel is a science in itself. Here is a link to the catalyst:

One of my friend's dads does something similar and swears by it. He is currently testing it out as well and is going to tell me the results. But he claims more drastic changes in fuel economy than 2mpg, more like 15mpg. If it pans out I'll throw it on here and we can combine all these products for the most fuel efficient vehicle ever.

Even better than that. Put a clothes pin on the fuel line.
Works every time.

Keep watching, the truck's mpg calculator is slow. You can manually check for quicker results. What was your emissions retest? Thats why I sent you the SF28 to check emissions.

I have been checking the last six tanks manually; the three prior to the installation and the three since the installation.

I am currently on my fourth tank since the installation and will be filling up this evening, so I'll have another set of results to post. I'll do another emissions test this Saturday and post the results as well...as that was part of our agreement. But to be honest (and I think I speak for most of this forum) I wouldn't pay money for this if the only positive result was 'lower emissions' especially since I've seen how low the truck blows already. It would have to post some MPG results for me to come out of pocket with the George Washingtons.

I'm also going to leave the unit attached and see if there are any long term MPG results (posting back here and there) and also to see my dealer's reaction when he finds it on top of the tank...that'll be funny.

That 3rd tank averaged 10.7. (SIGH)
