It came back during the OC following the final A-Rx rinse, at that point I was not adding MMO to the oil I was using 4 oz of A-Rx. You won't see me bashing the product because not all problems can be solved with additives. I might try a HM oil now, but in all honesty the leak isn't bad enough to upset me.
I had mentioned to c3po that sometimes changing chemistry to clean something up is a good idea, and to give MMO a shot. His complaint was after 24,000 miles and a lot of filters he'd be done, and have a clean engine.
It doesn't matter to me what a person uses to clean his engine, I keep an open mind, read a lot and am not afraid to experiment with my beater. I have over the years seen first hand what MMO can do with cleaning and I've always been impressed. I've also read about a lot of A-Rx success stories. If a person wants to try it I say go for it, they offer a guarantee if you're not happy with it you really have nothing to fear, and can always try something else.
I will however call a product out that makes claims that defy logic, neither of these products make such claims.
Demarpaint, can you elaborate on the leak that you were trying to treat? Was this a new-to-you car that had a leak, or was this a car that developed a leak after following your regular MMO protocol?
Cheers,

It is a 93 Aerostar that I owned for about 10 years and I had logged about 115,000 miles on. I had the leak for many years, slow from the rear main seal. As I said MMO did nothing in terms of stopping the leak, it has probably been slowly leaking for about 100,000 miles now, nice and slow.
I read a lot about A-Rx here as many did and thought I'd give it a try. I followed the directions to the letter, and changed filters halfway through the clean and rinse phase of the first treatment. I did two clean and rinse cycles. I expected filters loaded and heavy as a brick, they were exactly the same as any filter I ever removed from that engine. I also thought my oil would come out like black tar. That didn't happen either.
As mentioned above the leak stopped for a while [at least it appeared to have stopped], and then it came back. I had discontinued MMO use and was on the A-Rx maint dose when the leak came back. I'm not saying the product was bad, I'm saying the leak came back. I am also saying that my guess is my filters were light, and my oil wasn't black like tar because the engine was clean to begin with.
10 years is a long time and it is quite possible that seal was leaking since I bought the car. I paid more attention to it because I bought the A-Rx with resolving that issue in mind. This vehicle is considered to be our beater, not neglected but certainly not a car I am going to do major work on to fix a slow leak. If it were my Jeep or E-150 it would be another story.
