the issue of how the sludge was "before" ARX has been brought up since my last response... The sludge up top has never been hard. Since the first time I had a good look under it after buying it, the sludge has been very soft. I could seriously clean most of it off with a paper towel if I wanted to, this is why it is so amazing to me that it is still there, any cleaning product, (even something simple, like the HDEO and MMO mix) should have rinsed some away IMO. I chose ARX because I wanted gentle, but effective, I'm not sure why it isn't attacking this sludge, nor any other cleaners...

mdocod,
Question did you recently purchase this vehicle? If not why has it been neglected on oil changes? -dbdeland
pretty sure I mentioned this before in this thread, but I'll repeat this. I BOUGHT this vehicle IN this condition. with about 54,000 miles on the engine at the time of purchase. I was semi-aware of what I was getting into when I bought it. (knew it was an abused car, but got a good price on it IMO)

How about you changing your oil to say Walmart SuperTech and drive for a few thousand miles then post ? surely with photos. Perhaps your title will reflect a different view. -Frank
Let me ask this. Is supertech your most highly recommended oil for ARX treatments at this time. If so, why? (not just the simple "because it's a plain simple dino" that everyone throws around.) For a long while there: the exact oil that I used for the original treatment was RECOMMENDED by you and repeated in threads all over the place, Castrol GTX. I remember in the last thread (the one that was deleted, hey by the way admins, thanks, nice to be able to go back and check all the stuff we already discussed on this topic, oh WAIT , hehe, just kidding, WE CAN'T, lol)...We discussed the possibility that MAYBE the "new" anti-sludge formulations of GTX that were coming out at the time, (5w30) may have changed in some way to compete with ARX. I never received a clear answer on this possibility from anyone either. I'd be curious to know if successful ARX treatments have been done using the latest 5w30 flavor of GTX since that time. The 3rd cycle was done on havoline 5w30 conventional clean and 10w30 rinse, so I think I can say with great confidence that my choice in dino probably had very little to do with the results (or lack there of).
besides, I used ARX in my rodeo with decent, noticeable results. Obviously I am capable of following the directions, else wouldn't the rodeo treatment have failed under my supervision?
The more important thing, is trying to determine what's going on here... maybe there is more to it.. I have lots of ideas... what If the dealer I bought it from, used some kinda "engine flush" on it before I bought it, maybe the engine was even worse before I bought it. maybe the cleaning formula they used penetrated the sludge, causing it not to "react" with the fatty acids in ARX the way ordinary sludge does... I'm just thinking out load, anything to get ideas stirring... Surely, there must be some reason.

pulled the valve covers to inspect, he saw practically no difference. Similar to your experience so far.
I think roughly a year later he pulled the valve covers to replace the cover gaskets because they were leaking and he discovered that the engine had cleaned up enormously during the year since the 2 ARX treatments.-va3ux
this is perhaps the neatest thing I have read yet- this might make since actually.. maybe for some engines, the "rinse" phase gets stretched way out for various reasons. Needing MANY oil changes and many thousands of miles to finish. Seems logical, possible, something to consider.
--------------------------------------------
Another possibility... when I first bought the car, I put Mobil 1 Extended Performance 5w30 in it and ran it for about 4000-5000 (as I recall). this was kinda in the time frame that I was investigating more of what to do about how to clean it up. I figured the syn would do it some good while I figured out what to do... anyways. Maybe the EP penetrated the sludge in some weird way, making it not respond to ARX.
----------------------------------------------
I think what I might do, on my next oil change for this vehicle, is pull the valve cover, and at least clean the underside of the cover real good. So whatever goes into the engine won't be "fighting" as much gooo.. I don't want to disturb the sludge that's on the cam towers too much. It's not doing any harm. To me it's worth leaving there. (so I can play around with all the possible suggestions and help from bitog. lol)... maybe having the sludge on the underside of the valve cover removed will change the pattern of splash enough to get some flow over that sludge, or at east hit it from a different angle or something.
