WOW, I've been lied to !!!!!
I tested the BP 93 & the test shows almost 10% ETOH.
Took a 10 ml test tube put in 1 ml water & marked the line. Added 9 more ml water and marked the line (magic marker). Drained the test tube & put in 1 ml water......this morning I added 9 ml of the 93 BP...capped the test tube ....shook it up....let it sit a few minutes......the interface line almost doubled from the 1 ml mark on the tube......so in that 9 ml of gas is almost 1 full ml of ETOH.
So in the KC area there are BP stations that have premiums labeled 91 92 or 93......I'll test the one on the Kansas side that's changed owners.....he had a 92 that he actually showed me the invoices for ....as pure gas.
I have to admit though, the car's been running like a striped-***-ape & getting > 25 mpg????????
