We had to take a small sample from planes’ fuel tanks to check/get rid of water. There was always someone glomming onto those samples to take home to burn in their torpedo heater or something.A story.
I worked with this old boy back in the day that retired out of Ford garage in a small town SD.
We were all just shooting the bull and the topic of oil brands and things came up.
So one asked Henry what brand of oil he used in his vehicle.
He said that after changing customers oil he would drain what ever was left over into a bucket and that was what he used the entire time he worked a Ford garage.
All those little dribbles and slight teaspoons left in all those jugs.
