Air bubbles in ts2021 oil

Anyone seen this issue discussed anywhere? At first I thought I was getting water in my oil…it looked milky in the sight glass. I drained it into a glass jar and let it sit…no water…did this twice…no water…it is air bubbles. I am using 30w non detergent…pump seems to run fine

Air bubbles in pump oil is normal. The will settle after a few minutes
