Well I purchased CA-40 and it resulted in my gas car getting 6 miles per gallon less and pining when going up any hills it was supposed to add up to 10%.  I will not even bother putting it in my diesel! Learn form my stupid mistake!

Cheers

what is CA-40 i guess its a hydrogen kit you bought. I dont sell them or nothing but if the car has a mass air flow sensor it still should not have hurt your mileage it helps the older ones much better try unpluging your battery for an hour and put your ca-40 back on in that time start the process a second later start car drive let me know what happens. Played with mine a little i was told the sensor see its getting much better air flow and ups the gas as far as the denotation going have not heard of that before  

No, it is not a Hydrogen kit, but a Fuel additive that was supposed to aid in lubricating the injection pump and increasing fuel economy due to their unique blend!  It does not work though and so many farm shops are selling it.  Check the link in the original post.  

i would post it on their link and see what they have to say  

They do not have a forum, as their product sucks
