If you don’t stress it, you may not notice it knock on 87. Especially depending on what was in there before you added any.

Be honest!

I generally put the recommended. Prefer a clear conscious…also why I don’t do my own taxes. LOL.😂

I fill 91/92 - the same as in my SUV. No need to change just because it’s a loaner

Integrity is a measure of what you do when no one is looking. The Golden Rule is to do unto others as you would want them to do unto you. Finally…Going the Extra Mile is like returning a rental in better shape than you received it. Your example is appreciated!

Disagree. A loaner is an EXPECTATION at this price point. If you give me like, an M product, sure I'll use premium. But if you give me a base model whatever, it gets whatever gas is cheap.
