Side Note: I've heard that extractors will not get all the "sludge" out of the bottom of your oil pan. It makes sense, but then I started to think about it.
If the particles (if any) in your oil are "free floating", your oil filter will filter them out quite quickly, when the engine is running.
If the sludge at the bottom of the pan (if any) is hard enough to not get circulated with the rest of the oil, I kind of doubt it will even come out when you pull the drain plug. And, if the sludge were to break loose, the oil filter would pick it up quickly. IMO, the arguement doesn't make complete sense.
Pulling the drain plug is the best, but this seems to be a great alternative. |
