Well, the purpose i wanna try RIslone(the quart sized bottle), jsut once, is because ive read about it all over online....people that used it, semed ot have used Havoline(coincidence maybe) adn ran it for 1,500 to 1,700 miles maximum..they all bragged about all the junk and crud that came outta thier oil pan, so i am naturally,, curious too see what ahppens, thats all. I am aware of the dont drive it over 1,500 miles key.

I am already almost done with an auto rx 2nd rinse phase, meaning iive run it back to back, for a total of 2 cleans, and 2 rinses. Just thoughtabout some stuff, like people here say valvoline has a weak add pack, but dostn varnish the engine up as bad, other oils like havoline, have lots of moly....my theory/idea is, since moly coats the parts in engine, maybe it wont let rislone do as good a s job, as an oil with a weaker additive pack...
any ideas?
