Noticed the E content changing upwards after sitting in the tank a week. Did a quick experiment today. We all know about this but I was surprised at how quickly it happens.
Put some E85 that tested E68 in a cup this morning, figured I’d leave it overnight and test. After about 4hr, it looked like so much evaporated that I might not have enough to test now!
Turned out, I had just enough with a few drops to spare. It tested E81!!! Not what I expected!
