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:

I lived aboard my sailboat for 10 years. It had a Perkins diesel. I always changed the oil myself and tried a couple of different suction devices. What I found was this: If you don't warm up the oil enough (running the engine) then the oil is too thick to suck out. If I ran the engine too long then the oil melted the pump seals. That's how I broke both of them. I burnt my hand on the one with a brass cylinder, too. Mind you, the Perkins required 30 weight oil, not 5-30, so they might work better for a Hummer.
I prefer to drain my Hummer's oil pan because I feel it does a better job of removing an heavy sediments.
