This is a fantastic point! And when you break it down that way it makes me wonder why I’m not using a boutique oil. I’ll spend hundreds on bottles of bourbon that I’ll never open (for some reason I’ve taken to collecting them)...and when you think about it, it’s a waste of money. At least good oil would actually be doing something. I spend enough time reading/writing about oil topics, why not buy the best oil? I drive a ton, I extend my intervals past 5,000 miles, I keep my cars to pretty high mileage. I’m a perfect candidate to buy the best oil, yet I don’t. Perhaps I will.
