Hey everyone just a question am I supposed to not have a oil service dipstick in my car 05 c240 4matic?? some body said it is electronically controlled and my year doesnt come with one, my dealer changed the oil b4 I picked the car up in Oct.2011, I don't need an oil change now but I want to make sure the car will let me know when I have to just to be on the safe side) thnx

Yeah, sadly this is the trend on many new engines these days. No more oil dipstick. Instead you have to rely on a sensor to alert you of incorrect oil level. And we all know how reliable these sensors are....

However, as far as I know, even though you don't have a dipstick, you still have a dipstick tube, which means you can purchase a dipstick from your dealer if you wish.

By the way, you're posting in the wrong forum. Your car is a W203.

I believe it is just another ploy to drum up service business and limit warrantee liability by the auto manufacturers. Service recepts are down because the cars are much more reliable now, and as long as you follow the maintenance schedule- and yes, you can do it yourself and not void the warrantee- the warrantee is in neffect. Just keep receipts for any oil, filters, etc. you buy for protection against an unscrupulous dealer. I sued Nissan under the lemon law of NJ and won. Just keep detailed records.

FYI this is the incorrect size wrench, please dont mislead others if your not 100% sure. The correct size is 74mm, not 74.5mm

A 74.5 mm will round off the flutes on the oil filter housing

This is the correct filter wrench

Hmm... I have the 74.5mm Assenmacher (2175) and it's a perfect fit on our C300.

xXHotelCrazyXx

It is still too big...when you put a 74.5 mm socket on it, there is still too much clearence between the housing and the socket. I just snapped this picture to show the exact width of the housing. 2.92 inches when converted to mm is 74.1mm (the perfect fit)

let me see if I can settle this...

I bought a 74.5mm socket/wrench whatever you want to call it (from Autozone) and it fit fine when I test fitted it at the store but once I got home and applied force, it was too loose -had to wrap tape around the filter cover to avoid it slipping and stripping it- Ended up returning it of course!

Ordered the 74.5mm Assenmacher (2175) which Pete7874 recommended and it is in fact, a perfect fit.

I will use calipers to measure the inside of the tool to see if it is @ 74.5 or shorter when i get home tonight and I'll report back!

Pete7874

You may be right. With the 2175 on the housing, there is still just a tiny bit of play there. It works just fine and doesn't strip the housing, but I can imagine 74 mm socket would have been an even better fit.

xXHotelCrazyXx

I have a 2175 (74.5mm)lying around and it doesnt fit like the 74mm

I just use my hands. Unless whoever did the first service before you over tightened it passed the green marking on my vehicle, it is easily loosened by hand, and just as easy to tighten back to the green dots to have them match up.

Pete7874

I ended up stripping several plastic oil filter wrenches on mine because someone had tightened it so hard. That's when Assenmacher and a ratchet came to the rescue.

Now, last year I had the dealer do an oil change as part of Service B, so I'd be curious to see how tight it's on there now... I'll find out soon enough I guess.

If dial is still showing correct width, I read 2.936", = 74.574mm

.

xXHotelCrazyXx

It is a 74mm housing. Trust me, the 74.5mm does not fit properly. A mercedes isnt even listed as an applicable vehicle for that wrench. Here is a a guy who used a 74mm wrench (diy)

Thats not what the tag said on it when it arrived...It was all VW and Audi. (It list what engines also) and a C300 is not listed, which is why this wrench doesnt fit properly.

Silly question because I have read every post on the subject, but I want to be sure the Mityvac 7300 or 7400- whichever holds more, works well in draining the old oil. I am old fashioned in thati prefer to remove the drain plug, but if the mity vac is satisfactory, why not use it? Someone posted somewhere that MB recommends using the pump rather that the drain, and since am a belt and suspenders kind of guy, I want to "measure twice and cut once. Any opinion and suggestions are welcome!

xXHotelCrazyXx

The only reason why MB recommends they pump is to reduce the time the vehicle is in for service. Draining the oil from the pan is still a better method IMO

xXHotelCrazyXx

Also which is why they engineered the oil filter to be placed at the top of the enginer, so the technician can do a complete oil change with out ever having to jack/lift the car up and remove under tray fairings.

Pete7874

If you already have the extractor, why not do an experiment to find out. Extract first, then remove the drain plug and see how much more comes out. If not much, I'd say it's good enough.

....and tell the rest of us.

I am going to buy the larger extractor that holds 8.8 liters since my torn rotator cuff and other assorted physical limitations ( no "poor guy"s please) the mity vac is very attractive. Thank you all for your kind answers and rest assured they are appreciated. Maybe some day, as I have said before, I can contribute instead of just asking, but I am learning thanks to all of you. Again, thank you very much. It reassures me, living here in NJ, that there really are considerate people out there- they-re in NJ too, just harder to find because I live at the Shore and the vacationers are a rude sort- but not all of them,- just not a lot of them. Traffic becomes impassable, prices go up, and every business is dedicated to getting every penny they can from tourists- kind of like a super Mity vac for money if you have ever visited here between Memorial Day and Labor Day, you know what I mean. $10 and up for parking, $3- at least- for a 1/10th slice of pizza, $3 for a paper cup of cola flavored ice with some liquid really in it, and when the younger (teens) descent, nightly arrests at bars, on the streets, and at houses rented. Except for that, it still is a pretty nice place to live- I live in a small town on Toms River that is exclusively year round owners- and they are the nicest neighbors I can imagine. End of rant- thanks for bearing with me, but I am trying too get to know you members, and tell a little about myself so you don't think I am some lazy guy looking for free info. I have owned 8 Corvettes since 1972, 3 BMWs, an Acura, Lexus, and about 20 others- I am a retired teacher with no kids, so it really might not be a character flaw. This is my dream Mercedes, and I fully assume I know nothing about it until I learn. tTrying TO AVOID IF IT AIN'T BROKE, FIX IT TILL IT IS".

I bought the expensive Hazet filter cap because the others differed in the spec for the size.

Samstag Sales has these, just put in your engine number IIRC. Fits perfectly, much better than the thin sheetmetal caps that I have for my other cars.

I think the size is 74.1mm.
