I am thinking of using Auto-Rx on the Black Beater... looking for some updates from you guys that have used or are using it currently... Thanks
So do you have to run synthetic after the treatments or can you stay with the the trusty 15w-40?

Was considering purchasing some of this but the research I have done suggests MMO works just as good if not better than ARX at a fraction of the cost... http://forums.noria.com/eve/forums/a/tpc/f/616604995/m/134100814
First thing I did when I got this truck was to give it an oil change, the oil was horrible! really really sludgey, the filter also looked like it had been on for a very long time.
I did a compression test on my new 93 7.3 IDI NA.
(fully charged batteries, engine was warmed up overnight with the block heater, radiator was hot to the touch.):
passenger:
1: 220-320-380-400-410-420
3: 200-290-340-360-378-390
5: 180-320-380-422-445-456-462-472-480
7: 220-310-360-390-400-410
drivers:
2: 200-300-360-392-405-420
4: 220-318-362-398-416-422
6: 220-316-358-390-400-410
8: 230-325-370-402-418-422
going to give MMO a shot and see how it does, ill do periodic compression checks at the flush intervals.
Yes that's what I was doing, they went maybe 5-10 psi higher after 2-3 more strokes, so I only counted 6 strokes, except for cylinder #5 which went farther than the rest.
"A low compression reading on the first stroke followed by gradually increasing pressure on successive strokes indicates worn piston rings."
looking at some other peoples compression results, they got:
Passenger side front to back
#1 - 300, 380, 400, 420, 420, 420
#3 - 260, 300, 380, 400, 400, 400
#5 - 300, 380, 420, 440, 440, 440
#7 - 300, 380, 400, 420, 420, 420
Driver's side front to back
#2 - 300, 380, 400, 440, 440, 440
#4 - 300, 380, 400, 420, 420, 420
#6 - 280, 350, 400, 420, 420, 420
#8 - 250, 300, 400, 420, 420, 420
so thats obviously healthier than my engine.... but then again when I changed my oil it came out with thick sludge, nearly all the oil, so I think with a good cleaning I will get some compression back.
The problem with mmo in these engines, is that it evaporates very easily, and leaves with the blowby through the cdr only to be be burnt in the combustion chambers. After you add it to your oil, walk back to your tailpipe, you will smell it burning.
