Used my oil sucker to change oil today...I had been using an old dead shopvac as the collection reservoir but went back to the plastic gas can cause it is a whole lot easier to pour the used oil back into the empty 5qt M1 containers. Only drawback with the plastic can is the fact that it kinda crushes, but it maintains enough shape to work ok. All I need it to do is collect the oil until I move it to the empty M1 jugs, so it works well enough for that.
I normally check the operation by pulling the drain plug, and as always it was dry as a bone. That made me think that it's probably a good idea to change the copper washer on the drain plug anyway, so did that. Also used the oil sucker to suck the fluid out of the PS pump and changed the filter on it as well, refilled with M1 ATF. I figure it will take a couple of changes to get a complete flush and changeout of the fluid in the PS system. One thing that may not be obvious from Wilton's post is the need to get the engine up to operating temp before using the oil sucker. I learned the hard way that the oil sucker doesn't do a good job of sucking "cold" oil...got it partially drained and couldn't get any more to come out. Guess I could have put it back in and warmed it up, but I went ahead and finished by draining from the sump into my oil collection pan, which put me back into the situation of making a mess as I tried to transfer to the empty jugs. The local Jiffy Lube takes the recycled stuff with no problem. You have to sign a statement that it doesn't contain any "bad" stuff, but hey, it came out of a MERCEDES, so it is primo waste oil ;-) Royce Engler 1985 300TD Turbo 290K
