Yes, I run premium no ethanol gas, no ping at all. In fact, I need to do some experimenting with the vacuum brake--back it out a little at a time to see if I can it to the point where it will ping, because on a long hill, it seems to run out of power more than I think it should. But that will have to wait until spring--it's well below freezing here in Minnesota and I don't have a heater in the old Ford. Regards, Rod
