Seeing an improvment?
You might take a look at your plugs now, and a month or so later.
If your burning some HHO in with the gas, the plugs should be getting a lighter shade of brown.
Also check your tail pipe. It's probably a bit sooty now. But in a month or so of HHO it should be clearing up some.
Remember your only gaining about 10% with the HHO. So you wont see much of a difference unless you apply some Scientifically accurate measuring devices.
