Be careful when running any type of oil thru your engine while parked in your yard. A few years ago I had a turbocharger come apart. After replacing the turbo I fired it up and the smoke cloud was so thick someone called the fire department. I had cops and firemen coming thru my driveway gate because they thought my shop was on fire. I had to wait till 1:30 one morning to fire it up and drive several miles up the freeway to clear it out. Neighbors don't take kindly to their backyard picnics getting smoked out.
