I used Shell V-power for a little time and didnt notice any difference in how my Maxima ran compared with Sunoco and Hess.
So, I'll stick with
for now.

There was an article about it in motortrend or car/driver, don't remember which one. It said a bunch of automakers got together (honda, toyota, bmw, and a couple others) and agreed on specifications of gasoline.
There are stuff that causes deposits and crap in the engine, but no one can pin down what the stuff actually is, so they can't put a minimum "standard" on gas. So these automakers decided to figure what minimum detergents and additives and stuff are needed in the gasoline to help prevent deposits, which they now call top tier gas which theoretically SHOULD be better for your engine.
But the article also said that using non-top-tier gas wouldn't void the warrantee or prove to cause damage. It just said that Top Tier is supposedly better for the engine.
(It's analagous to using a lower octane than specified by the manuf. you don't get all the horsies, but you shouldn't cause damange or void the warrantee either).

I'd love to see how Costco (where I get my gas) would test out!

the car and driver article had a warning about regularly putting those over the counter additives. the article did not want to mention any brands. i usually stay away from them unless the car is pretty old.

1.3.1.2 Base Fuel. The base fuel shall conform to ASTM D 4814 and shall contain commercial fuel grade ethanol conforming to ASTM D 4806. All gasoline blend stocks used to formulate the base fuel shall be representative of normal U.S. refinery operations and shall be derived from conversion units downstream of distillation. Butanes and pentanes are allowed for vapor pressure adjustment. The use of chemical streams is prohibited. The base fuel shall have the following specific properties after the addition of ethanol:
Contain enough denatured ethanol such that the actual ethanol content is no less than 8.0 and no more than 10.0 volume percent.
Contain no less than 8 volume percent olefins. At least 75% of the olefins shall be derived from FCC gasoline as defined by CARB (advisory letter, April 19, 2001).
Contain no less than 28 volume percent aromatics.
Contain no less than 48 mg/kg sulfur. At least 60% of the sulfur shall be derived from FCC blend stock.
Produce a 90% evaporation distillation temperature no less than 290°F.
Produce IVD no less than 500 mg averaged over all intake valves.
