It was the additives I am sure. It has happened before.

I was running hot, hard and fully loaded and in those circumstances, my
owners manual calls for high test. My owners manuals both also forbid
any alcohol mix of any kind unless you need a little to get to real gas.

I also have a modified engine set up manually like a 1981 engine would
be with no computer controls and the minimum pollution controls.

It only happens with brands that have that super cleaner in them or too
much alcohol, other high octanes like Esso work great.
