Just FYI, I installed a flex fuel sensor and gauge so I didn't have to worry about crappy fuel. All of the fuel in SA right now is showing e76-e78 on my sensor.
I bought a couple of drums of E98 so I can stay at E85 when I go to the track.
Do you ever find e85 that's higher than 85%. I ask cause my cheap test tube reading can vary from 85-89% or so. I get fuel from HEB.
