What's a more accurate E85 tester than
Quick Fuel's E85 Tester?
Quick Fuel's E85 Tester has worked for me the handful of time's I've used it. With that said, I might just be crazy with something I noticed recently.
I filled up with E85 a few weeks ago, and it was E80 per the tester and after about 20 minutes of waiting. While cleaning out my garage over the weekend, I found the test tube in a box that I forgot about. I looked at the percentage and it was now around E73.
I found the tube on it's side, so could it just be a case of some of it spilling? Could it be that I didn't screw on the cap tight enough and x evaporated? Either way, I'm curious if anyone else is using another E85 tester.
