A class project was for students to bring 9 fuel samples from 3 different gas stations. Then we would test them. This would give us a couple hundred different samples in a typical test. We would use the home test, (water method) and the electronic tester sold through Kent Moore/SPX to GM. Results were all over the place. From 0% alcohol to a high of 13.5% the last time we tested which was a year ago. With the limit now raised to 15%, I wouldn't be the least bit surprised to see 17%-18% out there. Your lawnmower won't like that stuff.

I would expect it even a pinch higher just based off what I saw years ago, if the fudging stays the same.
