I posted here about what I call the short list of supplements that I am willing to use. And then people put replies in that wound up getting the post locked. Please do not put replies in my posts that will get my posts locked up. I don't want to argue with anybody here. I will use what I want to use and everybody else can use what they want to use. People should be able to discuss things at this website without getting into silly arguments. I had nothing to do with the orginal post about the printing company and 3-RX. I replied to the post but I did not post that information. I am not interested in posting anything about Auto-RX. If somebody else is interested in posting about Auto-RX please do so in your own posts. I may stop using supplements completely except for Regane in the fuel and maybe MMO and/or Lubegard Engine Flush in the oil. Even Sta-Bil does not have to be used in the gasoline (just use fresh gas) and Bars Leaks is not needed unless you have a coolant leak. I have not used Neutra in years. Like Johnny says supplements are not needed. He talked about just using a fuel system cleaner. He also in another section talked about how he does not believe in HM oils. Pennzoil Platinum or even any quality brand of conventional motor oil, changed at reasonable OCIs may well be all that anybody needs. MMO maybe would be a cheap solution for older high mileage cars and trucks and abused vehicles. At least MMO is a cheap method to possibly clean a dirty engine. If it did not work a person would not be out much.
