school me on mittyvacs
saw a diy with a member doing his oil change via this way.. i figured i should invest in one since it's not too expensive. which one is the most practical/easy to use?
it won't be used often, so i don't want anything electrical (if such a thing exists) i'd like to keep it as simple as possible.
also i'm used to removing drain bolts and replacing them with new seals etc.. obviously this isn't neccesary with the mittyvac... but is swapping seals something that should be done in general, when changing oil? or as long as the bolt isn't loosened, it will be fine?

I use a mittyvac to change the oil in my cars.
Works pefectly fine, and makes it much easier. No different than how they change it at the dealership.

I believe it's just a crush washer on the drain bolt so it can seat to imperfections. If you don't remove the bolt you don't need to change it. That's how they're designed.

I have a mityvac and it works great. I also use it on my yard equipment and for removing old gas from things like my generator. I still go under the car on occasion just to drain any sludge from the oil pan.
On the crush washer. I have never replaced one any vehicle I've ever owned and never had a drain bolt leak.

thanks for the replies guys. leaning towards that one mj.
in general, how much oil do you guys feel is being removed via this method as compared to removing the drain bolt? i've read that most vehicles sumps dont allow all of the oil to fully drain via the bolt. mittyvac better for this, (removing more)?

I have an MV7300. I'd say it pulled around 7.5L of the 7.8Lish in the pan. Maybe you didn't get the tube down far enough?
Which one do you have? I'd say 10min with 100psi inlet pressure and oil around 78C.

That's the one I have as well. I modified by buying a metric sized push-to-connect reducer plastic fitting to eliminate the stepped rubber adaptor between the two tubes. And another with a plug in one end to cap off the end of the tube when I'm not using it to prevent residual oil from dripping out the end of the draw tube.
Next time around, I'd buy the one with the vacuum pump. The hand pump is not well made and tends to lose the ability to create a vacuum.

dammit...
for those of you with the vaccum pump, how is the quality? i don't want to use something twice and have to junk it.
