396 miles out of a 97 Grand Cherokee
As it says I have a 97 G. Cherokee with a 4.0l six it has a 20 gal tank. Best before HHO was 11 to 12 mpg in town 14 hwy max(about 280miles to a tank).The Jeep is in excellent shape always maintained. I am using a Super 2 generator with a homemade dual EFIE.At first with baking soda and distilled water I was getting 13 to 14 mpg in town 15 hwy running 15 amps, but it would climb and eventually blow the 30amp breaker. I always use regular gas from the same pump.
I now use rainwater with a little baking soda.The amps start out at 9 and now max at about 15amps.On a trip to VA from NY I Made It on One fill up averaging 18 to 20mpg.I ran the tank till my low fuel light came on at 396 miles.Me and the wife were amazed!.Truck never ran smoother.I must say I always use the cruise control as much as possible to regulate the throttle better.

The difference at idle very noticeable.Jeeps tend to idle a little rough (meaning rich).With the HHO it idles and runs remarkably smooth.I have yet to get a check engine light so I guess its happy.

How far have you got the EFIE turned up, ie how many mVs are you adding?
Just wondering if there is even more to be gained.....

This is veery incouraging. I also have a 97 grand cherokee. I've been averaging 16.5 in mixed driving with only a cold air intake. Can't wait to get my HHO and EFIE setup and installed.Big Grin
