Possible chemical interactions?:
In 1977, I sold a 71 Chevrolet Chevelle Malibu to a friend. I had used only 10/30 Quakerstate since new; but my friend liked Castrol (which I have mainly used for Japanese and British bikes). He switched, but complained that it was using oil. Previously, the 307 (Quad carb, aluminum high rise manifold, Hooker headers, aftermarket dual exhausts) had about 70,000 miles, but no oil consumption could be noted on the dip stick, between 3,000 mile interval oil changes.
After a couple years, he in turn sold it to a mutual friend, who went back to the original oil and then had no notable consumption between oil changes.
Did the additives conflict?
Thus my encouragement to chose a quality major brand of oil and continue with it, if at all practical.
Please do not take this sideways to an oil thread...it is not winter and oil is not the topic...just making point regarding the possible reaction of chemical additives between brands or types.
