Factory Onboard Mileage Computers

[AmachinistJeff]

I would like to stress the importance of manually checking the mileage of you're vehicles when using HHO generators. It seems to me that the lean conditions detected by the O2 sensors has a direct effect to Mileage computers readings being high. I have seen many posts where people use their vehicles factory mileage computer and claim 32 miles per gallon, for example. When checked manually however, Milage is actually down to 18, for example. I am just speculating here: I beleive these computers must use O2 sensor readings, Engine Rpm, and Mph readings to acheive they're readings. This is fine for closely calculating MPG for Gasoline. When HHO is introduced the equation would no longer be relavant, if these three criteria are used for the calculation. Please post only manual mileage calculations. Then there shall be no errors. Thanks
