Changed the oil at the time due to a cold snap & felt terrible hearing the motor waiting for the 15/40 Delvac to circulate. At the time, I was 2 quarts shy on Delvac so I had my mechanic throw in 15/40 Rotella he had on hand. I'm wondering if that had any bearing on the bump in Calcium & Phosphorus.
My next sample will be with Rotella T5 10/30. I'm interested to see the difference. Results are from Blackstone. Thanks for any input.
