I have a 2007 3500 Express Van with the 6.0L gas engine. My wife and I recently purchased it with 39,000 miles on it. I have no idea what the previous owner was using for oil and have searched here with out getting a clear direction. The owners manual does not specifically call for a synthetic oil, only the vague GM6094m standard.
I am getting ready to change the oil and was leaning toward Durablend 5W-30. Engine does not consume oil, smoke, slap/knock, etc.
Any opinions about using a blend in this engine or going full synthetic?
Thanks
