If it was M1 High Mileage it was seal swellers in addition to conditioners. Why I asked. If he thinks a conditioner alone will stop leaks I doubt it. From what I've read A-rx has swellers in it, but thats a hugely expensive way to go. Much cheaper to stay with a High Mileage oil. In the summer I consume more. I just top off with a thicher High Mileage oil, does the trick.
You are right Auto-Rx does not swell seals, is just cleans the gunk around seals that caused the seals to lose pliability. I believe using Auto-Rx is better than going the High Mileage oil route, but nothing will fix a mechanical problem but replacing what is broke.
