HI:
Since the oil has not been changed for 3 years(storage) I want to do the "ounce of protection worth pound of cure" thing.
Take out as much of the old oil and replace it with fresh.
When "take off" happens do the proper drain oil after running a while to heat it up.
Right now I am a prisoner of my belongings (old cars,motorcycles,pinball machines).
All trappings of a misspent "yout"!
