i usually open the filler cap and let out the dip stick prior to drainage. Although I'ver never tried to blow into the orrifices, I would like to think that I drained out as much as possible w/ my method.

I ususally have about an extra half quart kicking around so i just run that through and let it drain out. Comes out with the dirty oil mixed and then starts to look cleaner.

if you really wanna drain as much oil as possible, unscrew the lower oil pan and let it drip for a bit. a lot more work tho since you have to reseal teh pan

Yeah, don't do that.

removing the cap/dip stick helps prevent a vacuum from forming.  Think of it this way.  Take a straw in a drink.  Put your finger overtop of the straw and lift it out of the drink. (pulling it out of the drink would be like when you remove the plug.

No liquid escapes because of air lock.  Remove your finger and it pours out.

I always lift the dip stick up a tad and go ahead and unscrew the cap.  I also usually walk away and get into something else so it usually drains for at least 15 minutes.

Yeah, but thanks to the pcv system, there won't be any air lock in the system. Think of the PCV system as a hole in that straw just below your finger.

By all means, take the oil cap off before you drain the oil, to make sure you're gonna be able to get it off and add new oil. But even if you don't it'll still drain just fine.

Not to be a negative Nancy here, but is the moisture from his breath bad for the motor?

Probably not really...then again it wouldn't be good either.

There's so much oil that's gonna be left over in the bottom of the pan and up in the engine anyway...if you've ever dropped your lower oil pan, you know what I'm talking about. So all these little tricks are pretty worthless...just take off the cap, take out the plug, let it drain for five minutes or so (personally I only give it like two minutes), then plug it back up. If you measure how much oil you get out from five minutes to fifteen minutes, you'll find it's very little.

I put my hooptie on ramps, makes it a lil more comfy under there and just let it drain for a little bit.  Then I take an extra quart or two and flush it through there, gets her really clean.  Let that drain for a while

0w30 starts very thin, makes your car work less hard, starting and warming up, thereby allowing it to run more efficiently, hence fuel efficiency

the angle of the car on the ramps allows the oil easier and allows more oil to flow than a level ground change...only reason i suggested.

when i do my oil change, i use an Air Bellows, like a foot air pump, Attach it to the valve cover where the oil cap should be, and give it a few good pumps.  I usually get about 2 extra cups of oil to come out.

that just sounds so bad...like horrible...like it hurt my eyes reading it.
