The following tests were done to compare pre-Auto-RX, during-Auto-RX, and post-Auto-RX. Unfortunately, it appears there's no difference??? I'm quite surprised.


MOBIL DELVAC 1300 - 15W-40 - 1500 miles each test
DODGE AVENGER = 61200, 62700, 64200 miles
Test #1 = Normal oil.
Test #2 = Oil + Auto-RX additive
Test #3 = Normal oil (after Auto-RX cleansing)


(If the metal is not listed, the value = 0.)
WEAR METALS (ppm)
#1 #2 #3
02 03 02 iron
01 01 01 chromium
04 01 02 lead
02 02 02 copper
02 02 03 aluminum

OIL ADDITIVES (wear prevention)
#001 #002 #003
0337 0375 0395 magnesium
1936 1899 1871 calcium
1123 1019 1008 phophorus
1388 1369 1376 zinc
0049 0035 0034 molybdenum

CONTAMINANTS

Maybe this is a testament to the quality of the oil or it could be the "perfect" combination of oil, engine and operational parameters. Couldn't ask for any better wear numbers, even for the pre-Rx 1,500 mile interval. Probably see a bit higher wear numbers with a longer OCI, but if they are equally as good as these you should have nothing to worry about. Have you been using Delvac 1300 for the life of the engine? With 10,000 mile intervals? (Wow! Have you done a UOA after one of these long OCI's?) Mostly highway driving? I don't think I would even fool with another Rx treatment with these results.
 
Well this is such a short run that I'm not sure you can say much except all of these analysis look good. What interval were you planning on running next time?? And perhaps a longer run with the AutoRx would have geen good. Perhaps someone here has some thoughts.

Perhaps you should email AutoRx with this question

I have no idea. What are (in)solubles?

The Avenger ran natural PennZoil for the first 40,000 miles at 3000 mile intervals, and then I switched to Mobil Delvac 1 at 10,000 mile intervals.

I can run 10,000 miles because I drive nothing but highway. In fact, most modern cars are running 10,000 mile intervals (5000 severe service)
 
"12.9 12.7 Cst @100C "

This number surprises me as I was just reading the Mobil spec for Delvac 1300 15w-40 and it showed 15.+ Cst @100C. Seems like a large difference but all of your analysis show the upper 12's. Nevertheless, I'm happy to see your numbers as I was thinking I'd be giving up some gas mileage using the 15 Cst products.

Do you mean ARX did no harm?
