Anyone use AutoRX or Neutra in a 200k+ mile application?

What the title says. If you've used it and had results, good or bad, I'd like to hear about it as I have a 200k+ mile honda I'm considering using AutoRX in.

Thanks

I used Neutra on my 85 Volvo with an oil analysis at 239,000mi. See post: http://theoildrop.server101.com/cgi/ultimatebb.cgi?ubb=get_topic;f=3;t=000418

This was just a maintenance dose to clean up the engine and fuel system. The engine was in very good shape before the treatment - just a light film of varnish on the cam visible from the oil fill cap and used (leaked)approx 1qt every 3000mi. Varnish is gone and oil leak is cut by half.

i did the suggested double-dose of auto-RX in my 215k mile toyota pickup (V6). seemed to clean it out pretty good although according to the records this truck has seen regular oil changes its whole life so one would hope it wasn't terribly filthy in there. the oil analysis afterwards came out looking pretty durn sweet

i can't honestly say i'm getting better gas mileage or it runs better or my windows roll down easier and the radio's louder

, but i'm pretty certain the oil analysis on this truck would have come back with a good amount of "gunk" in the oil with 200k+ miles on the engine....

if i didnt think it worked so well i probably wouldnt have four bottles in reserve...
