just gettin ready to do an oil change on my f115 yammie. anyone know how long to run the motor with muffs on to warm the oil up for the change? thanks in advance.........Bill
on the muffs? half an hour or more.
I usually simply suck it out the dipstick, you can also use the sump drain but it can get messy.
tilt the engine up to about 1/2 way for 10 min then all the way down to drain.
