One more thing, the engine should be at operating temp. This helps suspend crap in the oil so it goes out with the oil.

You can also get magnetic drain plugs that hold metal particles and keep them from circulating. It's really scary what they pick up, but don't worry, it's normal. Just wipe it off good and clean with carb/brake cleaner or whatever's handy before you put it back in.

*Be sure* to look for leaks after starting it back up, then check the level one more time.

Hey GD I think he was talking about stripping the threads on the drain plug and pan not the head of the bolt.

GOOD CALL JoANNE!! They can be a bugger to remove if you do not do the oil on the gasket.

Please read and listen to Ed's post also, very good points.

Yes, Dave I was speaking of the pan threads, thanks
