We don't change application instructions on a whim and we surely don't invalidate users benefits using previous applications. They just have to go off maintenance program (if doing the maintenance dose) for 1 oil change period-rinse for 3000 miles. They have then caught up to new application benefits. Now go back to maintenance program.
Just to reiterate! Stop using any Auto-Rx (if you're on a maintenance dose) for ONE 3000 mile OCI using a Group II or Group III oil. You want to minimize any polar bonding activity that may occur while you're trying to liberate deposits from the metal. Then go back to whatever you want (preferably using the maintenance dose).
When I read a post from someone who wants to make there own application I know they never read the Auto-Rx application let alone the FAQ and frankly are negating Auto-Rx chemistry that is formulated to give them the best performance-save oil cost-increase MPG.
If you do the math new application instructions save money we try to increase Auto-Rx Performance while lowering costs.
I firmly believe new application instructions are better and will indeed, after rinse mode is over, produce more usable benefits. Going on maintenace benefits will keep the benefits at maximum performance plus you never have to clean your engine again.
A note on seals. Anything with any seal swelling agent should be avoided while following the instructions. Allow Auto-Rx to remove the deposits that are making the seal rigid in a distorted shape. Once the deposits are removed (clean and rinse) allow the seal time to return to it's normal shape with a 3000 mile OCI without any interference from swelling agents to allow reseating of the seal. After that, go back to your HM or other oil of choice.
