I had purchased 2 bottles of auto-rx two years ago. Back then the basic application was to run the clean phase for 1500 mi and then the rinse phase for 2000 mi more. I now see that the basic application has changed to 2500 mi for the clean phase and 3000 mi for the rinse pahse. Have the formulations changed between now and then? The reason i'm asking is that I'm running auto-rx in my 2001 camry using one bottle of auo-rx that I have from two years ago.
Check out the new home page for Auto-Rx should be very user friendly, we are not done however far enough to upload and use what we have. Think you will find answers on questions that might come up easier.
