Did self oil-change today on my CLS 55


So I'm on my fourth or fifth oil change now. I wanted to send out a minor warning for the do-it-yourselfers. On my last change I bought two oil plugs and the correct copper washers that go with them. After the change I noticed a few drops of oil on the ground under the car. When I dropped the shields down there was a substantial amount of oil collected in the shields. After further inspection I noticed one of the plugs was leaking. I went back to the dealership and got two new plugs and washers. I found that the tolerance for the washers to the plugs is a little sloppy. Thus once the plug was tightened the washer left a small gap for oil to drain through. The good news is that I caught this problem before I ever started the car.
When I did my second change of the day (because the oil drained out when swapping plugs and washers) I had to make sure to center the washer with my finger nail while tightening the plugs. Long story for my message of- use caution! I'll tell you that I am convinced that had I gone to the dealership they would not have caught the leak before I left their lot.

I don't think I'd save much by doing it myself.
Let break it down:
Oil filter $25.xx
Two plugs $5.95 x 2 = rounded off as $12.00
9 qts synthetic oil $6.95 x 9 = approx $63.00
That's $100 already. Unless my dealer is taking care of me.

I spent this amount on products:
Oil filter and o-rings: $10 from Amazon
(2) drain plugs and washers: $12 from MB Calabasas
(2) 5qt jugs of Mobil 1 0w-40: $50 from Walmart
That's a total of $72 just for parts. I'd much rather do it myself. Plus, I get the piece of mind knowing it was done correctly.

and you don't have to drive to a dealer either www.oediscountparts.com
I've used them a lot for Cabin Filters, Oil Filters....etc.
I usually will buy like 5 pairs at a time of Copper Washers from the Stealership.
2 5 quart Mobil 0-40 from Walmart - Sometimes they go on sale for $23.99 per 5 gallon jug.
Just stock up for your next oil change...and after you do it, you have 10,000 miles to buy the parts again...and set them aside for the next oil change.
I am coming from an 09 C300 and always got 9qts of 0w-40 mobil1 and it can be hard to find at Walmart or Meijer, but the 5w-40 is always stocked.

Our being educated on these things makes us all more appreciative of the work that goes in, but more importantly knowing what could be missed.

Thanks again.
