I don't know how much interest there is in this oil, but here is a peek at it in heavy duty use (along with two oci's with Kendall 15W40).
This particular D13 is part of Volvo's XE13 package. The package was introduced a few years ago and uses what is referred to as "downspeeding". It is set up to run 65 mph at 1,150 rpm. I mostly cruise at 63 mph @ ~1,125 rpm.
The oil temp is free to roam up to 245-247F (119C ?). I'm loaded at 76K-80K lbs most of the time so I am usually at the upper oil temp limit. When oil temp hits 246-247 the oil cooler takes it down to 238-239 and then, up it goes.
The difference between 15W40 and 10W30 is that the 30 takes much longer to hit the max (after cooling to 238). The Kendall would blast from 238 to 246 in just over a mile. The Delvac 10W30 took three to four miles to get back up to the limit after being cooled. This isn't the least bit scientific but merely an observation that I noticed throughout each oci.
2013 Volvo D13 officially rated as 425hp @1700 rpm, 1750 lb-ft @ 1050 rpm
425 HP from 1300-1800 rpm
1750 lb-ft from 1050-1300 rpm
45 psi boost 1250-1500 rpm (down to 37 psi at 1050 rpm)
All three tests by ALS Tribology. Delvac was a NAPA kit and other two were Delvac Accutrack kits.
