By the way, take a look at the price of this stuff on google shopping:

It's NOT cheap. If they insist you use a bottle every oil change, yes, that's going to outpace "other products" pretty quickly.
But to go back to the OP, I don't see anything in Rislone's info that indicates it would interfer with Auto-RX. But basically, again, from Rislone's info, the end result of adding this product to your engine oil would be to turn it into the equivalent of a an HDEO 15W40 or thicker. A cheaper alternative would be to just buy an HDEO. Then you're not out the $10 or so extra and you can still run arx if you want.
