Vehicle: 1996 Audi A4 Quattro, MT (5 speed)
Engine: 2.8l V6 12 valves
Current mileage: 138k
Pre ARX:
Fill: M1 5W-40 T&SUV
Consumption: ca 0.5 qt/1k miles
UOA (8k mile OCI): http://i4.photobucket.com/albums/y108/moribundman/myUOA.jpg
Cleaning Phase:
After consulting with Terry, I added one bottle of ARX to a new fill of M1 5W-40. I ran this concoction for 1600 miles. Oil consumption was ca 0.5 qts during the ARX cleaning phase. I used FP during the cleaning phase, and there was a 1-2 mpg gain.
I cut the filter open, and if you care to search, I lost the URL, you will find a picture of the filter medium. The filter medium was possibly a little darker than normally. I can't say for sure, because I've never before cut a filter open. There were no globs of gunk or anything like that to be found in the filter. The drained oil was dark.
Rinse Phase:
2500 miles with DELO 400 15W-40
Oil consumption was about 0.6 qt/2500 miles, or about half of the M1 5W-40 fill.
The drained oil was very dark and I cut the filter open. Compared to the ARX cleaning phase filter, there was no discernible difference in filter medium appearance, hence I did not bother with taking a picture.
Did ARX work? I don't know. Today, I put in M1 5W-40 and will run this oil for 8k miles and have a UOA done. The numbers may give us a hint.
Before anybody asks why I didn't have a compression test done:
1. I trust no local mechanic.
2. The results are often questionable. The 12 v engine shows commonly good compression at well over 200k milkes, which does not necessarily indicate the rings are still good.
