My 05 C240 4Matic manual states 7.0l of oil (the non 4Matic is 7.8l). When I drain and fill with 7.0l and check it after a drive and rest it shows to add 1.0l. Using the trick to see the exact sump measurement it reads 6.0l in the sump ( I suppose the other liter is still in the engine and soaked in the filter).

What gives, does it really take more oil than the manual specifies?

maybe you are confusing quarts with liters?

Pit-Pony

No confusion, using L in Canada. 7L just doesn't cut it as it asks for another L for a total of 8. Why?

I thought the c240's use 8.5l of oil. I am not sure that that manual you posted it right, might wanna check. Thanks

I obviously have the owners manual. The numbers are right but the car wants more.

When I look at the attached image in the earlier post, I see 7.5L (not 7.0L) for the C240.
I suspect that the warning device is designed to advise in 1.0L increments.
Maybe if you put 7.5L in at first, you won't see the warning.

Edit: Sorry, I was looking at the non 4-Matic number.
I see you have a 4-Matic, and the doc indeed shows 7.0L.
Still, maybe 7.5L would do the trick.

The 2001 owner's manual I have for my 3.2L V6 says 8.5qts (8.0L) with filter replacement. Same for the C240 (no 4-matic that year). But the dealer has never been able to fit more than 8.0qts. (Any more and you get an MFD overfill warning). Since it's out of warranty now, I do my own oil changes, and when I put in 8.0qts, it measures out to 7.6 to 7.9qts.

So yes, I think the owner's manual capacity statements are inaccurate. Best to call your dealer service dept and ask them how much goes into your exact model and shoot for that.

My manual for my 2002 c240 says 8.5l, its a 2.6 v6. I just bought the mityvac 8.8 liter capacity top sump. I could have gotten a different brand for a lot less cheaper but it was 8 liter capacity and i was told i would have to empty it out before i could completely extract oil because it would overfill. If you search the forum, you will see that everybody puts in 8-8.5 l in their c240.Depends on how much they can extract out i guess. HTH.

Why would MB publish 7.0L for the C240 4Matic and when you do that it prompts for another 1.0L, ridiculous.

I ended up adding the remainder of another bottle (another 5/8L) for a total of slightly over 7.5L and it no longer complains. When I try the trick readout it now shows 6.8L in the sump after sitting overnight. I'd just hate to overfill it.

The dealer tech told me they always just add 8.0L to every C240 no matter which model.

Either the computer measurement is far from accurate or a good 1.0L remains in the engine and filter that never fully drains into the pan.

I agree there is no reason why a 2.6L V6 with 4-matic or without should have different oil capacities.

Your dealer comfirms what mine says (8.0L) then that is what I would add. I would do so in increments until you get the oil overfill display in the Multi function display. Then siphon off a bit until the display doesn't come back on. A PITA for sure, but better than leaving it 1L shy of full.

The computer measurement is quite accurate on my 3.2L. It reads 7.9 (qts) when left overnight. I put in 8 qts, so it's only .1 off.

Why not just use the distick tool and set the level to the maximum?

Pit-Pony

I think the oil pan is slightly smaller on the 4Matic due to the space needed for the front transfer case.

My computer reads a quart low in dyno mode.

What is the trick to see the exact sump measurement?

120 bucks for a dipstick?

Looked it up at my fav benz dealer in florida, they have it for
75.

It is a disingenuous argument to object about the cost for an optional tool, when no objections were voiced about the savings realized from selecting this economy vehicle, instead of the higher quality and luxury offerings from Kia and Hyundai, for example, which include that feature as standard fare. It is reasonable to conclude that the production-to-consumer costs for including that sliver of metal would be many times the approximately 20 cents saved. It is expected that much of those savings are passed directly to the consumer.

Pit-Pony

Well my dealer looked it up in his shop manual and the C240 4Matic takes 7.5L contrary to the owners manual that had it at 7.0L.

I don't think the dipstick was really a cost measure as much as a convience thing. They assumed that owners would prefer to just look at the display on the dash rather than use the dipstick. However, they didn't anticipate that so many people would miss it. That's why 2006+ vehicles have a dipstick once again.

That is an excellent, reasonable explanation. Thank you very much. Wait a minute…

Who suffers, I mean enjoys, greater convenience by the omission of a dipstick?

Does the owner who never checks the oil lever realize greater convenience from a vehicle equipped with a cap instead of a dipstick? Presumably they know that hood thingy opens, but would be hard pressed to actuate it quickly.

Does the owner who always checks the oil level at every fill up benefit? The on-board system prohibits usage if the vehicle is parked and refueled, as the time duration is too short.

Does the owner who purchased a dipstick tool and carries it in the cargo area benefit? The tool must be fully cleaned before storage, including the little crevices around the plastic guides, to ensure the used oil doesn’t stain the interior. The cargo area usage must be carefully controlled to ensure the tool isn’t damaged. The tool must be cleaned prior to usage, to prevent crud from entering the engine.

Does the service shop owner benefit? They must purchase and maintain sufficient tools for each work center. Additionally, they must train and maintain documentation correlating models to tool measurement millimeters. They must also ensure that the tool is located and used properly for each service visit.

This examination found lots of groups who now suffer with greater convenience.

There is an undocumented feature on my MY 05 C320 Sports Coupe. There is a hidden storage location for the oil level dipstick tool.

With this tool storage, those who purchased stick-less vehicles now have a superior oil level solution than those with the factory dipstick.

A very nice "undocumented feature" indeed !
Thanks for the pics !

Ok I guess I just don't care that much. I use the computer thing and I would never be bothered with the dipstick.

The attached image shows my two mods for the newly-discovered dipstick tool storage location.

There is now a notch to locate the position of the dipstick tip end and to drop this lower into the panel. It was easy to cut this with a utility knife.

A laminated label was attached to the blade, listing the acceptable range, showing the location for that range.

Please feel free to copy these improvements, which are to be called: "the wingless Dipstick Tool Mods".

and where do you dipstick i cant find a tube on the engine
