You have to drain all the oil out (complete change). Preferably while its still hot as when oil cools it allows the "gunk" to settle out of the oil (not good). You will probably also need to change your oil in another 500 to 1000 miles to get any residuals out of it, just to be safe. I have been considering this, but I have just changed my oil with expensive castro syntech. I will probably use a cheaper 5w40 oil for the 500 to 1000 miles as It will be immediately wasted. Then I will put some castro back in and change it every year or 5k miles.
After all that, it will still be cheaper than going to a "stealership" for their $150 coffee.
