Wow not to shabby....

 

7th tank - 17.1 mpg. This time I watched my instant mpg closely and tried to get the best milelage I could. I never thought I would be able to break 17 mpg. I'm really happy with this product. It's nice to know that it will pay for itself and then start saving me money.

If gas goes up as much as some people are predicting, then I might try running 89 octane in it as well to see if that would result in less money per tank.

 

Im glad it seems to be working for you, ive been looking at this for awhile but hesitant to drop the cash and not have any results.

For the MPG are you just going off what the computer is saying on the IPC or are you actually calculating miles driven on the tank versus gallons needed to fill it back up?

Also, id be interesting to see how well this works with something like E85. I looked on their site, but they only list gas and diesel.

 

I've been going off of the DIC. It is about 1/2 mpg off from when I check it manually before and after install.

 

whats your latest average MPG???

 

Last tank was 17.1 on mostly city driving. That is 1.4 mpg better than before, but I was driving very conservatively on that tank.

 

It would be interesting to see the results of removing the catalyst now that you have several tanks worth of data. Just to see if the millage drops.

 

I never thought of that. That's a pretty good idea and it would be easy to leave it in place and just reconnect the factory fuel line. I might try that and see what happens. Once we get some better weather I'll crawl under and see how easy it is.

 

I have one from Ecosystems that he let me try out for free, and barely noticed anything.

 

8th tank - 16.7 mpg by DIC. I guess 17 is about as high as it will go. After 8 tanks it seems like it is pretty consistant so I will just report back if anything changes.
