Use the best of both.
Yes, I do use prem.
Premium name brand gas is no different than regular unleaded name brand gas with the exception of a higher octane rating. The ONLY reason to use premium over regular unleaded is if you are experiencing pre-detonation. It does not give you more power. It is not the best, only different.
Pure gasoline, without ethanol, is another story.
Some name brands add detergents and such to differentiate their brand, but it all comes from the same refinery.
Having said that... It is your money, if it gives you peace of mind to buy more expensive gas, go for it.
