Premium once a month?
Hey guys, I have a 2006 Ford F-150 lariat, I always get regular gasoline, but I heard that once in a while it's good to throw a few bucks towards getting premium, is is true? And why?

I've taken to using mid-grade sometimes, especially from the 'first tier' stations like Shell. This is to get the better additive package of the premium for $.30 less. I guess you know that mid-grade is mixed right there at the pump out of Premium and Regular. I found on recent trips that any of our vehicles get better mileage on it. Modern engine control computers have the ability to increase ignition advance for better efficiency based on information from the 'knock sensor'. Since 89 octane will stand more advance without knocking, you could actually see a little more power, which would be reflected by better mileage at a given speed since it would require slightly less throttle.
Whatever, I see a difference so I use it sometimes, particularly now that gas is cheaper.

Top tier gasolines are given this classification because ALL their grades of gas have a high end additive package. In Detroit, top tier brands include Shell, Mobil, BP, and even Costco which I use. Costco states that their regular gas has 5 times the amount of detergent that is minimally required. So if you use top tier gas, there should be no reason to run premium for the detergent content.

There's literally no difference between the lowest and the highest tier of gas other than octane. It's definitely better to get gas from a Top-Tier station, as they use lots of detergents and other additives that make their gas of a higher quality, but use whatever octane the manual says.
As for bbender's question, it's possible that E-85 could solve your issue. It has a decently high octane (100-110), but has a very low energy/mass compared to pure gasoline. A lot of people with heavily tuned cars run it, and can see significant performance gains from it if tuned for it.
