While reading a caution on Ebay concerning various "add ons" that claim to increase fuel mileage,( ) I came across this comment from the mechanic who was issuing the warning, Quote "I have run a "Smacksbooster" cell in a Jeep Cherokee 4.0L. I was able to maintain a steady 25-30% increase in economy with a MAP enhancer. If you want to build a cell, build this one, it is fairly cheap and requires no special parts best of all if you use KOH (potassium hydroxide) and distilled water it typically requires no cleaning or maintenance except for adding water. UPDATE: I have tried the Smacksbooster setup on a 1998 Subaru Outback 2.5 DOHC. My trip was from Salt Lake City, UT to Portland, OR, 1600 miles roundtrip. I was unable to get an increase in mileage at all. In some cases, I saw a drop of my usual mileage. I have made this trip without the generator before and recorded all mileage readings. My conclusion is either it is impossible to trick the engine ECM or that the load put on the small engine is equal or more than the efficiency obtained. UNQUOTE. I'm inclined to think that this mechanic may have a vested interest in this particular hydrogen booster, but am also wondering if the hydrogen could boost engine efficiency just as the addition of small amounts of L.P.G. can apparently boost the efficiency of certain diesel engines!
 
That's right Steve.

I was forgetting about the use of cell phones to control engine management in diesels. No wonder they need an O2 sensor

A good many later model diesel engines have an O2 sensor, and they use it to regulate the operation of the EGR system. My VW diesel has one.
