Mercedes car.. Pull the drain plug and oil shoots out,hits the frame and goes everywhere except into the bucket... Stevie Wonder could have designed this better.
Yeah, that's not how you change engine oil on a modern Mercedes.Mercedes car.. Pull the drain plug
If only they could... i don't know... make the drain bolt at least be angled down a bit more? OE can't design well it seems.+1 on the top-side extractor method as OE designed for it.
Pretty much any modern vehicle is this way...All too often the German–designed vehicles are needlessly complex or have glaring design flaws like this. Their engineering reputation is grossly overblown. And I'm saying this as someone of German heritage.
There may be other considerations.If only they could... i don't know... make the drain bolt at least be angled down a bit more? OE can't design well it seems.
I have acess to aldata but not an extractor lol. I looked at the area and "Thought" it would be ok..... It wasn't.Mercedes official service information on that car probably says to use an extractor from above.
So, yep, carefully engineered, actually. They knew that this would be a problem and specified a different procedure.
But one would have to actually read the service information, and spend the $100 on an extractor, to know that.
Don’t you have a subscription for this kind of service information?
I am an “amateur” and use Mercedes factory service information from WIS. I don’t make a mess like this as a result. If you’re going to keep working on Mercedes, I can share how to get a copy. But I bet AllData would say the same - use an extractor - if you have access to AllData.
How many threads will you author, complaining about Mercedes, before you, as someone who charges other people for your work, join the “amateurs” who have good information, and stop making a mess?
I mean, as an experienced professional, you couldn’t see where the oil was going to go, and at least put a funnel there?
Here is the most important Mercedes tool in my shop:

I initially thought I could prove your wrong since my RX 350 is pretty straight forward with both the oil drain and oil filter being super easily accessible. Then I remembered you have to disassemble the entire air-intake just to change the rear bank of spark plugs. You are correct, most of the them are bad at designing for maintenance and only care about putting the thing together.The OEMs all engineer them to build them, not do routine maintenance. None is better than another.
