Hello all,
I wanted to post my recent Black stone labs UOA on my rig with this Mobil delvac extreme 10w30 syn blend (CK4)
167,000 miles on motor.
10,600 miles on oil with 1.5 quarts added.
Ac Delco oil filter
S and B dry air filter
SUS viscosity @210f 65.7
CST viscosity 11.79
Flashpoint 420
Trace of fuel noted, no TBN test.
Aluminum 4
Chromium 1
Iron 18
Copper 2
Lead 0
Tin 1
Molybdenum 54
Nickel 0
Manganese 0
Silver 0
Titanium 0
Potassium 3
Boron 59
Silicon 9
Sodium 4
Calcium 1831
Magnesium 631
Phosphorus 1440
Zinc 1464
Barium 0
I had bought this oil on clearance, and haven't done a UOA in a few years. I had refilled with delvac 1300 15/40 also bought on clearance. The delvac 1300 refill is the CK/4 SN rated oil which I hear some people fret about the limit on zinc.. but I don't believe it should cause me any concern.
Have a great day folks.
