Not sure if I’ve shared this. I had a fuel truck driver, run out of fuel, driving in down-town Anchorage on W. Sixth Avenue. The 4600 gallon tanker stopped right in front of the FBI building at rush hour. Of course, his situation gained some attention from the backed up commuters and the Feds, looking out their blackout windows.
He, grabbed a five-gallon pail of Powerservice from the bucket box, filled the saddle, primed the DD15 and got it running. So if you are wondering if a engine will run on straight fuel additive,....
I drained the saddle when the truck got back to the yard. Didn’t appear to create any issues. Except, the driver was terminated the following day for that stunt.
