I thought this deserved a seperate topic. Recently I heard here that if you use Auto-rx with synthetic (or specifically, any oil with esters in it) that you should double the treatment interval from 500 to 1000 miles. Frank and Terry, is this true?
I always knew that if you're fixing a seal you should run RX with conventional oil, but what if you're just doing a cleaning?
I'm going to put in Auto-rx in my mom's Probe GT, and will be putting it in with her current batch of SuperSyn (she's put very few miles on this batch so I'm not dumping it until after the treatment)
