Yes an old John Deere will burn it up .. Just have some spare spark plugs handy in case the foul out I try to go to the same pump at the same station when I’m home. It’s when I travel I get concerned. In Canada they mark their pumps differently Also the bulk fuel delivery man makes mistakes and puts the fuel in the wrong tanks. It a crap shoot. Truck stops are your best bet only diesel at the island pretty hard to screw that up
