This uoa is of the very oil used for my recent voa post. Super Tech is on Volvo's VDS4 approved list so I gave it a try. My wallet was extra thin at time of purchase so it made sense to try it.
This oil is API CJ-4/SN
In use 1/4/14 thru 2/23/14 running mostly the northern tier of the U.S. from Maine to North Dakota this oci. Lots of very cold starts and lots of idling, too. Not to mention many hours of stop and go in Boston, NYC, Chicago and even in the middle of nowhere because of bad weather accidents. I stay loaded to near 80k lbs.
Engine miles/hours = 301,644 miles / 7,780 hours
Oil miles/hours = 18,308 miles / 567 hours
When idling in the cold the ECM adjusts the variable geometry turbo to maintain decent heat in the engine. The colder the air the more manifold pressure it made. During long idles in temps of -20°f or colder it would show a good 10 psi of pressure and maintain 185-193°f oil temp (depending how bad wind was blowing).

Blackstone thought the tbn/tan was out of wack so they retested and got same result twice. Considering the VOA numbers the UOA look good. Very good tbn retention, or so I think.
I should have titled this " confessions of a former oil snob". I have always thought it had to be delo, delvac, or rotella oil in my engine. I think I'm past that now....
