I only fill up with Costco, Sam's, Shell, and Walmart.

I just feel comfortable with those brands.

And you're right, it may not be such a good idea to go to those 'rinky dinky' gas stations in the middle of nowhere. No telling what they do.

Most of these additives have the same properties, just with slightly different ratios of chemicals.

So, not to knock truckers, but any time a trucker pulls in to fill up there tanker, there are a number of quality control measures that they are expected to take. When they take them, you're generally guaranteed a good product. When they don't, its hit or miss. Some are expected to do some pretty complicated math to get the ratios right (generally for ethanol blending). There a lot of little things that can go wrong, and unfortunately you don't usually find out until its already offloaded in to storage at a station and delivered to a customer, regardless of whether its from Costco or Shell.

As for Ethanol... yeah, I'm not a fan either.

Um, saw a Jet Black E92 this morning. It was in my garage. /endthreadjack.
Well said, Ben. I was unaware of all that information.
