I bought my J30 68Kin May. I did not know the history so I changed the fluids out.
The oil had 2k on it by the windshield sticker. It looked like it was straight from the bottle on the dipstick and peering in the oil fill hole looked a little varnished but not bad. I said what the heck and did an Auto-Rx cycle anyway. When I changed the oil it was the blackest mess I've seen. I also noticed when wiping the dipstick off to check the new oil level that a dark stain was coming off onto the rag. Pretty much convinced me that it does get in there and slowly soften/remove old burnt on deposits.
Auto-Rx is heat activated from what I've read which allows it to clean the rings up where flushes/solvents would evaporate.
The J30 is running stout - I'm happy.
I did the transmission too. I just flushed(12 guarts) it a couple of weeks ago. The fluid went from new looking to a deeper red. Shifted good before - still fine.
Will post update if anything goes south.
