say during peek crusing weather i check my edc like every 2 weeks or so, but thats if i was using the york alot, never changed the oil personally, because i'm always putting new oil in. what i did was empty the york completly when i got it, filled it with 12 ounces of oil and then made my own dip stick so i could always keep it around 12 or so. i have yorks on both my bagged trucks
the jimmy
