Ten years ago when I began experimenting with different technologies to achieve higher fuel economy, I just assume that getting 50-80 miles per gallon (80-129 km) was normal with System / HHO water installed.

Whenever you have a system that limits you brought your vehicle for repairs, it will eventually be a headache if you struggle with failure when you head somewhere or are away from a particular repair shop.

If you took your car to the same dealer for oil changes and other work, the dealer will simply review the files on their computer.

Many people are frightened by the process, yet that does not really need to get involved.

The other is the general wear inevitably happens with time. The moving parts in the vehicle must be replaced from time to time, and this is usually part of your regular service check.
