I heard this from someone. It makes sense, but no one does it this way.
First, dont let the car completly warm up. The thicker oil will catch more dirt. Next, keep the drain plug out for a long time. Get as much oil out as possibe. Then run a couple of quarts of new oil through the engine with the drain plug still out, to help get some more crap out of the engine. Put drain plug in, add oil. Remove filter, fill the new filter with new oil. Disable fuel and ignition, crank engine over till oil pressure builds up. Now you can finally start the engine. :lol:
