Well I got the auto RX liquid and mixed with my engine oil. This is the second auto RX treatment, after this interval I was planning a switch to synthetic oil. I know they advise a rinse cycle after using their stuff. I guess my question is do I need to do a 2nd rinse cycle or can I be fairly confident in just throwing in the synthetic stuff after this treatment and oil change interval is up? Thanks all.
