I started using auto-rx in my oil at 343,000 miles, and up until 367,000 miles doing 3 Clean and Rinses followed by the Maintenance dose of arx I went through 22 oil filters in that 24,000 mile span, so I know auto-rx works.
I was talking with a member on here who told me he did auto-rx on his 1988 Ford Van and the only thing arx did was slow down a rear main seal leak, he told me that while doing a Clean and Rinse his oil came out normal and that his oil filters were light as a feather, I said, how can this be, he told me he used MMO in his oil 500 miles before an oil change, I was skeptical, I could not find anyone having any problems with MMO by searching the net. I talked with my Dad's friend who was UPS mechanic from 1960-1998, he said he had been using it since 1955 with no problems.
I went ahead and added 12 ounces 500 miles before my oil change, as soon as I put it in the oil and drove out of the driveway I felt a difference. The car was just flat out more responsive. I changed the oil 500 miles later and it came out very dark. I changed the oil and took the car for a drive, it did not feel as responsive so I added 8 ounces of MMO with the Maintenance dose of arx. One thing that was odd was that when I changed the oil the drain plug magnet was spotless, with just auto-rx in there as a dose there was some goo.
I had always had a problem with the number 1 cylinder fouling spark plugs even after putting in new valve seals, when I put MMO in the oil this stopped, I have had the same spark plug in there now for 6 months and I checked it yesterday and it was spotless.
I still think auto-rx did a good job but, I started this process at 343,000 miles, at 330,000 miles me and a buddy changed my oil pump and it took awhile for the engine too build up pressure, he told me that I had some junk in there. MMO has now stopped my lifter tick, auto-rx would probably have eventually done this, who knows.
Back in 1999 I changed my intake manifold that had the EGR provision and the EGR port in the manifold was stopped up with carbon, I did a GM Top Engine Clean and fogged up the neighborhood, I did another top clean a year later, and nothing, of course I had put on an intake with no EGR provision.
I can also say that for many years I ran a 180 thermostat and for the last year I have been running a 195 thermostat, the valve seals were replaced at 350,000 miles and who knows if the old valve seals had me gaining more crud.
I still like auto-rx but my engine with a carburetor is alot different than the vast majority of fuel injected engines that run cleaner.
I also have to give some credit too Johnny, the retired Pennzoil guy who turned me onto Pennzoil Platinum, I have noticed that the oil has come out darker.
So I am running 5 quarts of Pennzoil Platinum 5W-30 with 1 quart of MMO and 4 ounces of auto-rx.
I have Pmed many people on here who know what I am doing and many of them are doing the same thing, there are quite a few auto-rx users who are putting in a pint or so 500 miles before there oil change.
I am no longer getting involved in any fights on this board because all I care about is what is best for my engine. I feel that with both auto-rx and MMO in the engine it is like having Batman and Superman working too clean things up.
I Pmed Helen too get her permission and I caution everyone that she will be keeping an eye on things.
I will give some final thoughts, I cannot say that auto-rx is better than MMO in the engine, but I think both products together in the engine make each other better.
Auto-rx did a fantastic job of cleaning my:
1) Differential
2) Transmission
3) Powersteering
I now have 372,000 miles on the El Camino, so I have been cleaning this engine for 29,000 miles. The only reason I tried MMO in the engine was because of what a member on here told me.
Lets keep any discussion civil.
