N=1 means nothing because…
N=1 means nothing because conditions vary considerably as does quality of engines. When I sold my First Gen Highlander it had 550K and still ran great also. No one had ever done anything inside the engine. It only used 1 qt between oil changes which were 7500-10,000 mi. Mobil 1. Oh, and I drove that thing like it had 9 lives and the price of gas didn’t matter. My scandalous driving record is proof. Many trips fully loaded into the Appalachians. Here’s a tip I learned early. Unless you drive your SUV like a soccer mom, get Bosch rotors / brakes. Shop brand brake parts were a joke. Tried some other high end brakes - Stoptech, EBC, Powerstop. None were close to Bosch in holding up to fully loaded mountain driving.
