First I just want to say how pleased I am with the improved performance I have received by using your product. It is worth the price...because it does work!
I do have a question for you. This weekend I will be starting my second rinse phase. After this phase I am going to start with the Auto-RX Maintenance Plan adding 3 oz. of Auto-RX to the new oil as recommended. My question is...with the Auto-RX Maintenance Plan can i use one of the name brand ( like Castrol or Pennzoil ) "High Mileage" motor oils?
Thanks,
John
And thanks again for the fine product and great support and answers.
