Didn't PT (Patrol Torpedo) boats have three V-12 Packard aircraft engines? As such, I would expect them to require 115/145 octane aviation fuel. I'm not aware of any of that stuff being refined any more.

Even 20 years ago most of the guys I knew flying R-4360 Pratts were using 100/130 octane and limiting manifold pressure to prevent detonation because 115/145 was unavailable.

I don't know what the displacement was on the PT boat engines, but I would not be surprised at a fuel consumption of 80 to 100 gallons per hour (per engine)!

I know somebody on the list will have a better memory than mine on this subject.
