10% mileage increase....

[Fredness]

Jacob's Mileage Master box. Would NEVER have considered them, but a friend ordered it for his '00 Ranger 3.0L and it set his CEL. He shipped it to me to see if it was the box and I went from 220 miles per tank to 244! I have been driving it harder with the box becase the increase in bottom end was so nice. With 300 miles on it, I can say it does work. This was installed without bigger wires and with the factory plugs at 77,000 miles on the clock. Going to do 8.8 wires (MSD) and new Motorcraft platinums with an increased gap to see how it really runs....

If you get a consistent mileage increase after 5-10 tanks I'll take it semi-seriously.

Definitely keep us updated on your gas mileage results. I get 16mpg so anything that helps would be a real benefit to me.

Second tank, same results.
Going on a major road/camping trip tomorrow. Will be able to post highway #'s too.

Yeah, this sounds really interesting! Get back to us!

how much does this thing run?

 

[MrShorty]

When establishing a claim such as this, it's important to eliminate all other variables. So, just to eliminate this possible variable, do they make you use oxygenated gas in El Paso during the winter? I would estimate that I've gained 10% sinc Mar 1 when they eliminated the oxygenated gas they put in the pumps during the winter.

I'd also like to hear more about it and how much it costs?
