I figure running one of those puppies through after a few thousand miles is equivalent to top tier. Just don't buy from a sketchy gas station and you should be g2g.
Redline SI-1 is a better alternative IMO. Lots of testaments of combustion chamber pics.

The long and short of all of it was this: The gas is all the same. Whether you're buying it from Sam's, Costco, Shell... Doesn't matter. What's DIFFERENT (and what allows the ability to get it labeled as Top Tier) is the detergents.



More specifically, it seems that it's the AMOUNT of detergents added to the fuel as opposed to the exact formulation. There are one or two companies that do have their own formula, but most apparently do not.



More usefully, it seems that running non-Top Tier fuels on occasion is generally not going to do you any harm so long as you are running something through the tank occasionally with higher concentrations of detergents to keep the "innards" clean.



It's far more important to ensure you adhere to minimum octane levels and avoid stations with low turnover to ensure you aren't getting a tank of gas that has degraded (or worse, has water in it). Also, don't fill up while the tanker is filling the underground tanks either to avoid contaminants that have been stirred up during the tank fill process from making their way into the tank in the car.
Yep, definitely beating a dead horse. All good points from you.
