Has anyone or is anyone using a Fitch Fuel Catalyist? If so are there any MPG improvements? Ive been able so far to get my 03 V10 exc w 35's to 12.3mpg... looking at a flex a lite electric fan swap and Fitch next.. really shooting for 15+mpg...

 

Fuel additives always seem like snakeoil.......never heard of any reallyworking ....I have been looking at these Home

I figure if it doesn't add fuel mileage at least it will be smoother .....hard keep 35's balanced.........check the Auburn U test report.
here's another place to get some

Hmmmm, $271 for an Excursion system. Here's my opinion on how to get the best mileage improvement from that.

1) Keep track of all fuel purchases over a 1 year period.
2) Buy 2 tanks of gas with the $271, but "forget" to add those into the calculations.
3) Figure your fuel economy based on "forgeting" those tanks of fuel.
4) Depending on how many miles you drive, you might see 15 MPG with the "new" math.
5) Best part of this system is it works just as well for the fuel line magnets, the vortex air spinners, and any other quick and easy mileage improvement system on the market today.

I'm not being too skeptical am I?

 

i have the fitch fuel.... i have notice tiny, tiny teeny, teeny tiny bit. but nothing great i think or i just lost all of it when i did my hp upgrades. next is my flex-a-lite fan. #294 is the better one!

If you want the real deal on how to optimize your mpg these guys are pathological about fuel economy and you will be amazed at some of the modifications they actually implement.

I have a buddy you put it in the Fitch Fuel and he said he has seen basically not enough increased mpg to justify the cost.
