Somebody get illlojik the part number for a replacement oil filter cap.

Just kidding.

Not trying to revive a relatively dead thread, but I just changed my 08 C300. Pulled out 10 quarts with my pump...YIKES...and put back in 8.5 of Mobile 1 0W 40 along with a MANN Filter. I also changed air filters and plugs.

How'd you get 1.5 quarts more oil?

My pump holds 9 quarts. I emptied that and it filled another 1.5 quarts. Last serviced by MBZ of Laguna Niguel CA

"Last" service indeed!

When I changed the oil in my wifes c300 for the first time on my own, there were 10 quarts in it from the previous oil change. I think I posted a pic a few pages back.

Anyway, I used a oil evacuater and did it like the MB techs do by pulling oil from the top of the dipstick and I got about 8qt's out. Just for the hell of it I put the plastic tube extension on the evacuator and ran it down the dipstick tube till I felt it hit the bottom of the oil pan. I cranked the evacuator back up and low and behold here comes another 2qts of oil. I guess the dealership is overfilling it or maybe they just aren't getting all of the oil out with their evacuators since they just pull from the top of the dipstick.

Ya I got my 10 qts by putting the tube all the way until it it the pan bottom. I also made sure the oil was very warm (ran the car for a short trip two hours before changing oil).

yeah the oil in ours was warm, too.

I think the dipstick tube doesn't reach the bottom of the pan so every time the mb tech sucks out the oil they leave behind almost 2L of oil. then they dump back in 8.5 and wala you've got real close to 10qts in the pan.

Testing by other members have definitely proven your theory false. Do lots of searching on this thread, grasshopper.

For those who like to stock up when a somewhat decent deal comes around,

LINK: Autozone has a coupon for $10 Coupon off of 5 Quarts of Mobil 1 oil :LINK Valid until 09/17/2012.

So basically, discounting from $8.99 a Quart to $6.99 a Quart.

Not as good as the Napa deal of $4.99 a Quart but nothing to whine about either.

Oh, and I don't know if its nationwide, west coast only... Check with your local store.

NAPA has Mobil 1 on sale right now for $5.89 qt.

For those who prefer draining the oil from the bottom, I found a great video that shows you the location of the drain plug:

A much faster method of draining engine sump oil can be achieved cheaply using a common garden plastic hose fitting as shown in the photo.

The 16mm OD male end fits snugly into the top of a MB dipstick tube. The largest of the ‘Fluid Evacuator’ plastic pipes fits neatly into the opposite end of the fitting to provide a perfect connection.

I’ve not cut off the female threaded portion of the fitting because it makes handling the hose easier.

Someone else found that one of the transition bushings from the kit can be stuffed into the expanded top of the dip-stick tube, and the large nylon tube can be stuck into the bushing.

Both good ideas, sprouting from the Fluid Evacuator adaptor that I found that most of the dealers use.

.

Yes indeed.

The advantage of the garden hose fitting is that it requires only the largest of the three tubes to be used. This speeds up the process significantly (and is perhaps the equivalent of the dealers' adaptor).

FYI, Walmart now started carrying M1 0w-40 in 5qt jugs for $25, which is their regular price. It's a bit less convenient than quart bottles, but at least one does not need to wait for a sale.

Huh?

What model do you have? Why would it not be possible? It's not like the oil dipstick tube and oil fill hole are locked and only dealer has the key.

@Number5 .. my SL does not have dipstick so I wonder if the white plastic tube from the pump in your pic can simply be stick thru the dipstick 'cover' hole all the way to the bottom of the drain pan without hurting any type of oil sensors within the drain pan... btw, that pump looks like a manual pump? and what Brand is it?

G'day mitviet

I can't comment on your SL but I can recommend the pump.
It is made in Taiwan and sold in Australia as 'Primtech CJ-169-S'.

oil change, dealer's method

.

How can I make sure the dealer will completely drain the old oil?

If they use the extraction method, then it will be completely removed. If an engine has been designed with extraction in mind, then you can get as much oil out of it this way as with the traditional drainplug method. Whatever the few drops that are left in there are irrelevant.

Going back to our earlier discussion on oil amount for C300 4-matic, I found this diagram in another thread, and I thought I'd post it here as it clearly illustrates why the 4-matics have a smaller oil capacity (7.4 qt vs. 8.5 qt for RWD).

When I 1st joined the forum, and discovered the smaller 4MATIC oil capacity after much testing, I argued indirectly with this guy named Glynn about it, and he suggested that his "believers" straiten me out on this subject.

Great picture find!

Received from Fluid Evacuators today my dip stick adapter for sucking the oil from the oil pan. After years and years of doing the old fashion way, with this adapter and their different size hoses for their systems. This is by far the best and easiest method. I am even getting one of their systems for my dad!

The other package is The Retro Fit Source H7 HID 6000k 35W Morimoto Elite Kit!
