There is a difference. I run Mobil gas. I will never use Hess gas again. I've
used it about 4 times in my life, in 4 different vehicles and it pinged like
crazy every time. The last time I used it was when my Dak was new (92). I filled
the tank for a trip to the Adirondacks I made it from Hilton to Watertown (about
150 miles) and couldn't stand it any more. Bought a can of octane booster and
dumped it in and no pinging the rest of the way.
