Joe,
I have a gas station about 4 miles from my shop that sell 93 without ethanol. There is another one at the state line in Tenn. There are two stations near Coach that sell non ethanol. But in Chattanooga over half the station have non ethanol. What up???
In the TKO line, the higher the torque rating, the better the bearings are.
