Unleaded vs. Premium gas, does it make a differnce?

My father inlaw suggested I run Premium gas when towing the TT. Makes sense but not sure it makes a difference, any thoughts?

Not in a Tesla. LOL. Sorry, couldn’t resist.

But seriously. Our V10 in our little class C ran better on premium. The mileage was noticeably better but can’t remember how much. It ran fine on regular but for the extra money probably got the equivalent better mileage. Either way though it was still too thirsty. :).
