Plenty from way back but I haven't been here in years so you'll have to use search function
I will take a look and let you know what I find.
I posted a few years back about a $5 qt. of MMO restoring compression in 250 I-6 Chevy engine used in a boat we had. It did some nice cleaning and silenced a fair share of ticking lifters over the years for us. There are a few products mentioned all the time here that can do it, none that I know of that can do it as cheaply as MMO, and that have been around as long.
Pick your poison after you do your reading and let us know what you'd use after you do the search. It seems this topic is of interest to you and if you have an engine that needs some cleaning I suggest you read up on it here. Let me know what you think.
Point me to one other than Rx that will rejuvenate seals such the VANOS seals in my E46 BMW or Pajero/Montero 3.5? No M1, PP had any effect. But again, I never use Rx according to instructions, I saw just enough about 12-14 years back to know its potential.
I don't know much about BMW's so I can't suggest anything for the Vanos problem. How about a HM oil, or Lubro-Moly motor oil saver?
I read your A-rx use reply, and how hjyou ignore directions. If I read it right you use 2-3 bottles for 3 oil changes? That could be 6-9 bottles, or there about?

Rx Plus is available and stronger although early days for testing. I allocate 6 bottles per acquired vehicle and follow my own regime FWIW.

That would cost a fortune. Even three bottles for one dose is a lot of $$. Glad it works for you, I found cheaper alternatives, and my success with one product in particular dates back to the 1970's.
Maybe the new stuff will work better than the old and increase the satisfied customer base. Do you think they'll take the 2 bottles of the old formula I found cleaning up my basement last week for a swap? Or am I stuck with it? I'll post results. My neighbors V8 Jeep is ticking and leaking. typical of a neglected vehicle with about 150K miles on it. It would be the perfect test mule for the new stuff.
