Gotta love common problems that are never a real issue but when they do become an issue its kind of a big deal... I always change my oil using something that looks just like this I believe mine is 16 qts What happens is when you remove the drain plug, it falls onto the container and from there slides its way into the hole causing a slow down in the oil draining into the container. This always happens and is never an issue since I can just simply reach in and pull the plug out. Due to working in the kitchen my hands can withstand heat rather well so its never an issue. One of those, meh, its annoying but x many times a year over x many years its never been a problem........ til today. It was time to do my first oil change on the Mercedes, I jacked it up and removed the lower engine cover, slid a tarp under the car and slid the oil container under the oil pan. First thing that caught me off guard was the oil drain plug, it was tiny, 13mm, I started to remove the oil drain plug and noticed that it's very long, about twice as long as any drain plug I've ever seen, hmmm, cool I guess, so I remove the plug and it drops onto the oil container, as always it went into the hole, so I grab the plug and..... no go, oh shit! so after having my whole hand under hot burning oil (not too too painful) I have to switch hands, stick the 2nd hand in there after about 5 seconds of having it under the oil I gave up. Jumped up grabbed my wash bucket thankfully it barely fit under the engine, just enough to catch the draining oil. I ran around the back side of my car (drive way is not level at all, it slopes down to the street) I lay down as many paper towels as I have handy, about a half roll just to catch it, then run inside to the kitty's bathroom and grab the 40lb samsclub size kitty litter, run out side open it up and its nothing but lumps of wet litter and crap.... #@$@$# so I run back inside only to find out kitty litter is on our list of things to buy so I run upstairs grab 2 more rolls of paper towels and start to slop up as much oil as I can. I wouldn't have minded this so much if it happened on any other car, but the Mercedes holds... 8.5 QUARTS of oil. After removing the wash bucket there was less then 1 quart in the bucket, the oil container had maybe 3 quarts in it. I figure there was at least 4 quarts of oil on my WHITE driveway. As for the drain plug, turns out it was the prefect fit, the sucker wedged itself into the drain hole, even after it sat for awhile and cooled down I still had to use plyers to pull it out of the hole, there was no chance of getting it with just some latex gloves on, I will NEVER use that style oil container again, I should have said that 3-4 years ago but..... gotta learn the hard way I guess. For here on out I will use either a shallow bucket or the oil containers with the mesh/plastic screen tops I put the car back together, did the filter (love top side filters) and added oil, slowly backed the car down the driveway and parked it off my driveway, I slopped up all the loose oil to the point of it being nothing more then a wet feeling stain, then fired up the power washer, it helped a lot but clearly its still discolored, tomorrow I plan on picking up some soap and a good scrub brush, giving it a good round of scrubbing then another round of power washing.
