I saw someone hawking on another Forum and looked it up. Calcium Sulfonate appeared to me to be a detergent and corrosion preventer. It has been added to motor oil for years.
It is possible it works like Acetone. Burnt acetone in the exhaust fools the oxygen sensor into thinking the motor is running too rich so the PCM leans the intake mixture.
“Burnt acetone in the exhaust fools the oxygen sensor...”
Thats interesting.....does burnt acetone produce O2?
An O2 sensor in serviceable condition produces low voltage at high exhaust O2 content; and high voltage at low exhaust content - sensor range is zero to 1 volt, 0.45 volt is considered “stoich”.
O2 sensors are just that.....02 sensors - not HC, CO, NOX, or anything else that I know of....they use exhaust O2 content vs ambient O2, the difference is used as a “catalyst” (if you will) to generate voltage.

It was apparently unable to do so on Mythbusters.
