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?

Actually, high octane gas has less BTUs per gallon than 87 octane. Its claim to fame is that the engine computer won't ****** the timing and you'll get better performance under load. Whether it's enough of a mileage gain to offset the additional cost is for you to decide.
