That motor should run fine on regular,BUT. There never was a fuel system used that was more dependant on ignition timing for good power and fuel mileage. Even on regular they can be timed 5 degrees ahead of spec. If they will run ten degrees ahead with premium, you will make up the cost in extra mileage (they can get 18 if set this way and leaned out properly; instead of the 12-15 its probably getting) and the performance will be a great side benefit.
