I bet ya whatever the producer put in is pretty close to what we get at the station. I understand that there are probably some variations between batches but I also find it hard to believe that the contents vary wildly between production runs. No one makes products like that on mass scale. Shell cannot pump out a 10% ethanol blend and follow it up by a 25% blend because the blending goblin had too much to drink the night before and dumped a few extra barrels into the pot. I bet the mixture is probably very consistent. Unless you're intimately involved with this process, your guess is as good as mine and I think mine is better than yours

Anyways, one way to find out: http://www.fuel-testers.com/

For academic reasons, I am thinking about picking up a kit and doing a once a month sampling of my local Shell station that I usually gas up at. The place was built very recently so I am hoping it does not suffer from long term exposure and contamination.
I didn't suggest the distributor or station did any mixing. But again, the parent company knows what typical numbers are. They aren't sharing. That's what I was saying. The only way to know is to batch test on site.
