So this is my first analysis, and my first OCI with M1 0w40. I did notice a minor amount of burning in 3500 miles, refilled some, and changed it out at 4,000 miles total. I did not notice consumption with LM 5w40 but Ive been told it can happen when you change brands/grades. I sent them a note asking about the consumption and if there were any indicators why... Numbers look good but time will tell with a baseline. Thoughts?
Also, are the "coolant in oil" and "gasoline in oil" figures essentially "backdoor" compression/leakdown tests because its a way of showing if things are sealing right?
