oil dilution? Now I am showing my age to be even aware of this strange phenom.
Radial engines in aircraft back in the 60's and before used to use oil dilution - that is gas injected into the engine oil in anticipation of starting in cold ambient temperatures the next day.
Pilots/aircraft engineers have any experience with this? How do you know how much gas to put into the oil? Was there a guage to show the amount of gas going in or would u just hold the toggle switch for so many minutes? I believe the gas was burned off by idling the engine for a time before takeoff. How long would it take to burn off the oil?
