" I drove from CA to the East Coast with a CVHHO Unit installed on 1 of my 3 Kenworth trucks. I used 25% less fuel in the Kenworth truck with the CVHHO System installed then the other 2 Kenworth trucks without the system on the same trip with the same loads!! I also noticed there is no longer black smoke coming out of the exhaust pipes on my truck!! See pics on our Gallery page.

“I installed a CS138 hydrogen assist system recently and immediately noticed my Freightliner idling more smoothly with improved torque through the gears. More important to my profitability, I checked my on-board trip computer while returning home with an empty trailer and was excited to learn my miles per gallon had improved by 22%!”

"Just wanted to send out a kudos to you. Finished the install of your CSD78K system on one of our 2000 International 4900 vehicles. The engine is a DT466e which is a 7.6 litre turbo diesel. As you know, I have been building my own systems as well trying others for the last 2 years. I am so impressed with the kit you have put together. Excellent workmanship and what a complete kit! I would consider this a typical truck install, and everything I needed was there. Even the lengths of cable and hoses worked out well and thanks for the low profile tank for our install. Fired the system up and took some pictures. As you said, 3 LPM @ 38 amps! I ran it for 4 hours and rechecked everything. All is well, even the temperatures of the reservoir and cell. I may add a cooling fan to help the venting of the closed box. And with your system, I even have room for distilled water storage and a heater for winter use, if need be in some of our colder locations. Your experience is shining through in the quality kit you have put together.... Well done!"
