Zeracer thanks for replying!

I used 0W-40 up until the most recent change. I used 5W-40 Turbo Diesel only because I read somewhere here about a chart that has all types of oils acceptable for a Crossfire. Apparently 5W-40 is recommended for heavy driving.

Is this not true?

In regards to the oil quantity, I did use 8 1/2 quarts.
