My vehicle is now averaging 2 mpg more than before installing Fitch. This is for a 2008 FJ Cruiser automatic transmission. I have had the vehicle for a year and no matter how I drove I never got over 18.5 mpg combined highway and city. I drive about equal amounts highway and city. I drive a lot and have accumulated over 20,000 miles on my vehicle in little less than a year. Now I am averaging 20.8 mpg. It is hard to believe but this Fitch device actually works! I am very happy and impressed with this Fitch fuel catalyst. I have not changed my driving habits to test the catalyst. I drive the same as always and this increase is real. Thank you. I am going to post this on the 2 major FJ cruiser forums. – Jason Mowry –
Toyota RAV 4 - 2003
“We installed an F200 catalyst into our Toyota RAV 4, 2wd, 2003 the day before our
road trip to the keys. We did not have to refuel until after 5 days and obtained around 50 extra miles. We traveled over 300 miles in that trip. Today after 3 months, I consistently receive 50 miles (city + 1 day long distance commute) to 80 extra miles (city w/ 3 days long distance commute). So far, we are very happy with the results and are going to install a catalyst in our other vehicle.”
“My 2004 Subaru Forester Turbo (4 cylinder) was rated on the window sticker to get 19
MPG city and 23 highway. I had the Fitch 6T installed in late April 2005 and have averaged
22 MPG in the city. That’s a 16% increase, plus the car runs more smoothly and it cleans
up the whole fuel injection system even though I continue to use premium grade fuel. On a
recent highway trip I got 26-27 MPG (a 15% improvement over its rated highway MPG of
22). In August 2005 I ordered two more for both of our family’s other vehicles, a 1998
Subaru Legacy GT (4 cyl) and a 1999 Chevy Silverado pickup (V8). I also use the small
drop-in units in a gas tank for my weed eater and lawnmower. Before I used to have to pull
the chain several times and a lot of black smoke came out. Now they start right up with no
smoke!”

20 Year Old Honda - Never Ran Better
So far so good! Started every time and runs better then it ever did and I thought it was running pretty good before. In fact it has never started as good as it is starting now using Fitch. If it continues this will be one hot 20 year old car with 227, 000 miles and some rust. I'm getting 31 - 35 mpg, maybe it will increase some.
Even with using Fitch in my lawn mower, I'm cutting 12 inch or taller grass with year old gas and never missing a beat. Didn't run that good with new gas and my neighbors brand new mower bogs down all the time.
