C63 Oil Change w/ Mityvac :: Write-up and Photos
My shopping list:
- a Mityvac from Amazon.com
- an OEM filter (P/N 0001803009) from the local Benz dealership (Came with new O-ring)
- 9-quarts of 0W-40 Mobile 1 Synthetic from the local Auto Parts store
- a big crescent wrench for the oil filter cap
- a small slotted screwdriver for taking off the O-ring from the filter cap
- some rags
- a small oil funnel
- Just warm the car up. (I waited until oil temp hit 175-degrees F.)
- Shut off car.
- Remove the dipstick and fill cap.
- Insert suction line into the dipstick tube until you hit bottom.
- Attach the line to the Mityvac.
- Give it 10-full pumps and it starts to evacuate the oil.
- Towards the end I gave it a bunch of additional pumps every few minutes to get the last drops of oil out.

Swapping the oil filter was also a snap. I used a crescent wrench to take off the cap. A 32mm socket would have been better and it will also allow you to use a torque wrench so you don't over-tighten. When you replace the filter element be sure to use a new O-ring. It should have been included with your filter.
I filled the engine with fresh oil. Took it for a spin around the block. Checked the oil level and it was just under the top red marker on the stick. Perfecto!

BTW, nice write-up.
- I got the vac tube to go all the way down. I marked it with my hand and compared to the dipstick. They vac line goes about 1.5" deeper than the dipstick.
- I was about 1 quart low. Topped the Mityvac up to about 7.5 liters.
- 9-quarts got it back to full.

I am not sure that makes sense to avoid the $350 charge from dealer as if something happens related to you making a mistake, you are stuck with bill.
If you are doing this just because you want cleaner oil in between your service, then, dirsregard my comment above.
Nice write up anyway. Thanks for taking the time.




I always jack up the car and put it on stands and usually end up getting oil all over the floor and myself. I do get to have a good look around underneath for leaks, scrapes, dents, etc. I do get my oil analyzed.
I may not be too old a dog to learn a new trick.
Thanks

I still plan on having the dealer perform all scheduled maintenance.
I think my dealer charges $100 for an oil change...up to you if its worth the extra $30 to do it yourself. Probably kind of a "fun" job actually if you're used to working on cars, this will be one of those nice 15 minute accomplishments on a sunday morning that gets your day going

Good writeup OP!
- I got the vac tube to go all the way down. I marked it with my hand and compared to the dipstick. They were the same length.
- I was about 1 quart low. Topped the Mityvac up to about 7.5 liters.
- 9-quarts got it back to full. Right in-between the top two red markers on the dipstick.


Like I mentioned earlier, I was a bit low on oil to begin with. I evacuated approx. 7.5 liters of old oil. The old oil filled the Mityvac in-between the 7 and 8 liter line.
I filled it back up with the required 9-quarts.
The old filter comes out connected to the cap. The shaft remained attached to the bottom of the housing assembly.
