Pull the plugs and take pic's, I'd be interested in seeing how they look. Keep them in order cylinders 1-8 so you can see how its burning.
Synthetic oil just doesn't neccesarily clean.

Quick oil changes with dino is a better way.

Base oil isn't as important as getting results.

Also it does have PAO and so does regular Maxlife too.

For cleaning IMHO Delvac 1 is hard to beat, after 30k miles on that stuff the inside of my 603 looks like new!


I like Max Life and have used it a lot, IMHO its not as good as an oil as Elf, Amsoil, Reline, Delvac ect.

Zeus, Sorry to hear of your problem with the high oil consumption, and the gauntlet you are experiencing. The problem seems to stem from the the wrong type of oil (Dino), used at those 10000 mile extended intervals.

Since having changed to synthetic oils, and if you wish to continue using them, I would go to Mobil 1 Delvac in a 5W-40 weight, for it's cleaning effect. It is very high in detergents and anti-corrosive additives, to meet the Heavy Duty Diesel Req'ts. for that purpose. It can be also used in spark ignition engines-gasoline, as it is formulated for that use also. I would try this before tearing into the engine or selling it.

I would use the Dino version of Mobil Delvac 15W-40 $8-9./gal., and add Marvel Mystery Oil to the engine oil and to the fuel. Buy a 1 gal. jug of MMO, at Wmart for about $12.50, and use it as directed for mixing with the oil and fuel. It will turn the oil black pretty quick, and you may want to change it at 1000-2000 mile intervals, with a new oil filter. Add the Dino 15W-40, as needed for topping up. Do this several times before you give up on it. MMO is used in the USAF by 55gal. drums in older non-turbine engines. Gen. Aviaton too.

If all this doesn't solve the problem, I would use Dino HDEO's like Mobil Delvac Super 1300 or Shell Rotella, Chevron DELO, etc., and keep the oil consumption to more reasonable levels. Oil consumption or use is not bad for an engine, it's bad for emissions and the wallet. Don't tear the engine down, if you can reduce the oil consumption, by whatever means you can find that will help reduce or stop it. Good Luck.

I will agree with this, and with Hatteras. I will also add that 30-weight is simply too thin for a V8 like this. I will ALSO agree that yes, you do need to drive these cars hard and not necessarily baby them. Different motor, but my m111 burns ZERO oil at a 5k change interval, 229.51 dealer 5w40, previously 15w50 M1 (unnecessarily thick, so I changed). I have beat the crap out of this motor for 105k, and it has 165k on the clock.


THAT SAID......simply put, run the Delvac 5w40 (or M1 HD truck and SUV is what they call it now), then after 2k or so use the M1 15w50 SuperSyn and see what happens to your consumption

Update

I spoke with the Service Manager at the Mercedes dealer here. He was polite and listened, and apparently hadn't heard of sludging issues on the M112/113 nor the O'Keefe lawsuit in the US. He agreed it wouldn't hurt to approach MB Canada and see if they'll do anything to help. First step is an initial inspection at the dealer, I'm booked for an appt in about a week and a half. Then take it from there.

Thanks for all the replies and I really appreciate all the help.

I've been doing plenty of reading and research about sludge and it seems like there are plenty of examples of cars (especially post 1998) having this problem. Not just Mercedes but also BMW, Lexus, Toyota, Audi, VW, etc. Most seem to be related to a combination of city driving and extended oil change intervals.

I agree with you guys on the trying to clean it option. If I don't get any help from MB (and I'm not holding my breath there), I may as well try and clean the engine up using an appropriate oil or in conjunction with a cleaner instead of simply getting another engine right away. Nothing to lose in trying. If I can get consumption low enough, I'll be happy with that.

Drove the car today and it runs so perfectly, you'd swear there is nothing wrong. Watched the exhaust when I started it, especially in the morning, and there was nothing - no smoke at all. Same while driving. Bizarre. Unless my cats are sucking it all up...

So, who knows...we'll see how it pans out (no pun intended).

MBUSA recommends only the use of MB approved synthetic motor oil for all vehicles equipped with the Flexible Service System (FSS) as of Model Year 1998. Conventional petroleum based oils are not recommended but may be used on older vehicles.

What kind of Hack is your dealer?

manny - that is exactly the problem. Mercedes didn't recommend synthetic (as defined in North America) until after 2000 or so. Hence the lawsuit for 1998-2000 model year cars in the USA.

This car was bought and serviced at the flagship MB dealership in Canada, the downtown/Dundas St. dealership in Toronto. It was babied from day 1. The dealer was simply following Mercedes' advice re: FSS. That, sadly, is what caused the sludge. It went to 80,000 Km on approx. 17,000 Km intervals, using dino oil. Changed to synthetic at around 86,000 Km. I have all the documents (receipts and stamped service booklet) chronicling all the oil changes and intervals, as well as the oil type used. We'll see what MB Canada says...

Okay, I sure hope they will eat some humble pie & do something for you.
Looking forward to the outcome of this one.

On another note, just had my first "A" service done @ 15 k km.
Next service "B" should be at 30 k km, according to my display,but my service booklet states "A" service @ 20 k km and thereafter all "A" and "B" services @ 20 k , or once a year intervals.

Aside from that, my dealer ( so I discovered afterward ), used crappy Quaker State oil.

Thanks manny, will let you know how it goes.

If I owned that new C230 of yours, I would be doing an additional oil change in between the specified interval. So if it says every 20K Km, I would be doing an interim oil change only (not full service) every 10K Km. I may be a tad biased at this point though...

Use either semi syn Max life 10W40 or Syntec 5W50.

Either one will help your problem.

Heh, heh, great minds think alike.
I changed my own oil after 7500 km , then "A" service at 15 k km and you can bet I will " sneak " another oilchange in there, before the "B" service is do.

Nice. I wish the original owner of my car had been as sneaky.

Here are some pics of the oil cap and filler area. The reddish-brown sludge is visible on the sides of the filler area and also down lower on the actual valvetrain.

Pics aren't the best, but that is as close as my digital cam can get.
