In NJ a station is not required to mark the pump if there's ethanol in the fuel. I thought most name brand stations had ethanol free in their higher octanes. Apparantly Sunoco in Mahwah has ethanol in all their octanes, including 93 Ultra.
Meh, I'm hesitant to buy fuel from there again, the last batch of 93 that I got at lightning had a TON of water in it. Like turn the bottle upside down and the entire filler tube is water, and then some into the bottle.
Well shyte, that's exactly what I bought. I have a little left over in the can so I can test it. BTW the 93 does have ethanol, all the race gas there does not.
