Auto Rx and Synthetic ?

[ncirish]

My Trooper has the dreaded consumption issue and it is getting slightly worse at 63k. After reading and researching on this site I have decided to run some Auto Rx through it next oil change (2000 miles off). It says not to use it with synthetic (which is what I have run in it since 10k for the most part). Why is this so? I have heard that the Rx has esthers that would conflict with those in the synthetic. Now I can somewhat understand the no-syn during the cleaning and rinse phases, BUT the site also said to run conventional oil with a maintenance dose of Rx afterward to maintain the gains you had made. Now why is this so as it makes no sense, at least to my meager brain? I thought syn lubes were great cleaners if used religously.

I am pretty sure the ARx site says you can run any type oil you want after the treatments and rinses are finished. But I think the ARx folks prefer dino.

Use any oil you like during cleaning phase of Auto-Rx application. During rinse phase use a plain jane conventional oil for the 2000 miles (will cause no harm) than go back to oil of your choice. If you review Auto-Rx web site (FAQ) you should understand why we suggest a conventional oil for rinse phase.
