Makes sense. Very little detergent.

It has roughly double the normal HDEO levels of Zinc anti wear and Phosphorus extreme pressure additives. Hairy stuff if you forgot it was not normal oil and left it for a full OCI as it does not have any detergents. Straight grade aircraft piston engine oil is the opposite with some detergents but no anti wear additives.

Discussion is about automotive run-in oil, not aircraft pistion engines. And btw, AC piston engine oil does have AW components.

I would be very confused if a hard worked, hot running piston aircarft engine oil did not have anti wear additives in it.
