Thanks for the links. Do you have an opinion on this stuff, cincytt? I've got to wonder if it affects 02 sensors, catalytic converter, internal seals?

 

some claim a difference, i dont know if its worth my time. its cheap and if you can find it and have the time, wouldnt hurt to give it a try if you have an ageing car (year or miles).

i think the only way to hurt the car is if you put in to much or put in the wrong location(s).
