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?

The design of the engine determines what grade of fuel you need.
If you notice knocking or pinging or anything else unusual, step up a grade in fuel. Don't lug your engine, Watch your tach.
I have a Lexus 430 SC built to run on prem gas so that it all she gets.
