Let me start by saying that whenever I changed my spark plugs before Auto-Rx the plugs were either had some carbon on them or a little oily residue, the plugs I changed today had about 25K on them, when I took all of the plugs out there was no oily residue or carbon on them, the porcelain part of the plugs were white, the only thing that was worn on the plugs were the electrodes, I have saved the plugs and when I can get my neighbors digital camera I will post the pictures, I got on the internet and went to the site on diagnosing spark plugs and mine fell in the normal range, we always talk about how well Auto-Rx works at cleaning out our engines but this is a case where everything is working so well that the plugs look normal which is important because if the plugs are not functioning properly you could have problems or soon will have problems, I have not heard of anyone changing there plugs at 355K and having there spark plugs fall into the normal category, the plugs I changed today remind me of the spark plugs I changed back in 1988 when the car has 65K, I think that this is amazing Auto-Rx keeps your spark plugs functioning normal, maybe this could be because Auto-Rx cleans the ring packs or any other seals that are near the combustion chamber, I changed the plugs because I noticed the car was down on power, this was obviously because the electrodes were worn down, these are just my observations, I remember checking one of the plugs during the rinse phase and telling Frank how well they looked, he told me that Auto-Rx was doing something, but I cannot remember what Frank told me but I just cannot get over how well these old spark plugs looked when I took them out.
It is fantastic when a product does something that is not even listed on the bottle, also as usual there is no black soot on the inside of my tailpipes either, and the powersteering noise has seemed to go away just like Frank said that it would.
