Since your OLM is calibrated for ordinary dino motor oil, why do you think yhou are living dangerously running a synthetic motor oil this long? Any ordinary dino has been able to do this for many years. Before I retired, I, for 25 years, ran M1 in my daily drivers, driven 18,000 to 20,000 miles a year, with a yearly oil change. Now that I am now retired, I have gone back to using dino, any brand, because I only drive about 6000 miles a year now, and can't see wasting synthetic on such a short OCI.
Yes, you are probably right but I am a highly anal rententive overly compulsive detail oriented high math type and need to check my OLM every 45 seconds while driving. Once my OLM drops below 50% I break out in a cold sweat and begin to plan my next oil change. I would explain further but I have to go wash my hands.
