A question on fuel for a E-450 ford chassis
My neighbour and I both have Jayco Greyhawks on Ford E450 chassis. The same engine, the 6.8L ford engine. He insists on using high octane fuel, probably octane 94. I was considering using octane 87...

x2 on the Chip or Tune. Without one of those, no need to up the octane. And some Tunes take you to what they consider max for 87, then tell you higher is required for the higher versions they offer.
