I generally go to the local shop to change my oil (I provide the oil/filter and these places still charge $30-$35) and recently I have scene some sloppy work. I purchased a Liquivac for my off-road toys and it seems simple enough so I think I am going to buy one for my cars as well.
Any one use these on their H2?
How much of a bitch is it to get to the oil filter?
It basically sucks the oil out of your vehicle without getting under it and removing the oil plug, here is the vid:
