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...

I was a Ford tech for 25 years.
These engines are designed for low octane fuel.
The high octane fuel is "slower" burning. This will actually create carbon deposits in the combustion chamber.
These carbon deposits will flake off and jam a valve open causing engine damage.
I have seen it happen several times.
