I've had that thought too...I break the connections at the remote filter and use compressed air to (gently) blow the
oil through the cooler and hoses and let it drain into the pan, disconnect the coil wire and crank (20-30 seconds at a time, takes forever) until I show
oil pressure before I fire it up. There's gotta be a better way, I'm gonna try blowing out the old
oil and (slowly?) refill the hoses and cooler before I hook it all back up next time.
