I am getting ready to change the oil in my '88 E250 and was going to run some Auto-Rx in it. On their website it says to run it for 3k miles and then change the oil. An thoughts on changing it earier or later (I usually go 5k between changes)? I have never used the stuff and wanted to get impressions form those who have in our engines. Thanks

Auto-RX at OB, sounds like success is very possible if compression is low.
