Sprint mentioned the Auto-RX and then we heard about whatever else. I respect Sprint's advice here, though I wouldn't want to do anything to really clean out my engine too well anyway for the reasons I stated.
Also, I have to say that I am surprised Sprint does this, since it sounds like he's using a dino oil, and I've heard it's not good to switch back and forth...so would be interested to hear more about why he's doing this. Sprint?
As for the new member...I'm suspicious too.
