Always good to hear how well the E 550 is holding up, especially the E550. I am hoping to keep mine to at least 2025 if not longer.

 

I use to push my car so hard I probably got more kills then my boy. I'm not sure if spirited driving contributes to the oil burning at all. I kind of assumed it did and engine size.

 

Wow you cut the interval short? I never thought to do that.

 

I hit 100k two weekends ago. Looking at the MB vehicle record it had a fair amount of work done before I bought it at 97k, but given the car and where it was used prior it made sense. I'll likely be swapping out the front control arms and ball joints this summer.

Sweet ride it is.

 

haha i still floor it sometimes here n there
and spirited driving definately contributes to that , im pretty sure

yes maybe i shouldnt but i feel safer this way and if you do it by yourself its almost 2 times less $ .... *in hope that it will prolong motors life somehow also*

 

Mine just turned 129 000 miles.


The only major issue has been the rear air springs replaced under warranty.


I have had passenger side mirror motor replaced, the bolt on the roof tightened as the car made loud popping noise when body was "twisted".


I had Comand software updated few times to find revision that works for Bluetooth music streaming and does not kill the radio at times. This I don't consider car problem as it never was made for Bluetooth connection for music streaming. I see this a an improvement on the car.


I have had oil changed every 5000 miles...


All the talk about oil changes is so funny/stupid to me. The cheapest warranty for your car engine is to change oil often enough. If you have the Mityvac or another type of liquid extractor the oil change is very easy and low cost process to perform. While my car was under warranty I took it to the dealer for the 10 000 mile service interval but I changed the oil myself between at every 5000 miles. And this was a stretch for me as I was used to change oil at every 3000 miles but my driving is almost all highway so I'm fine with 5000 miles interval with oil changes.


I always use 0W-40 engine oil. It cost about $26 in 5 quart jugs. Filter is ~$16 from the dealer or Walmart. I change that only at every 10 000 miles.


I will keep changing the transmission fluid at 40 000 miles interval and this probably at the dealer


This car is a TANK! I will keep it as long as I can repair it. The best looking E-class with the hockey sticks in the front.


I would never buy the new E-class that looks so boring/stupid. If I need a car to look like that it would need to be the S-class and right now I cannot get to one. Perhaps later...


MB was not very smart to make all sedans look the same like other Germans did in my opinion...


But they did what they did...


About the engine oil viscosity (weight) rating.


If your car remains in warm climate you can raise the lower end number. Like I live in down south I could use 5W-40 or 10W-40 oil but I still use the 0W-40 as there is no difference in price between the oils. In cold winter climate you need oil with relatively low viscosity for cold starts so keep the 0W.


Similarly if, again, in warm climate you don't want to drop the high number. Keep the 40 so you don't loose oil viscosity during very hot days. Loss of viscosity means loss of lubrication...


My dealer uses 10W-40 probably for savings for their business but from now on as all my car oil changes are done by me it is 0W40 all synthetic.


And when I do my oil changes every 5000 miles the oil is NOT all black. It still has some of the yellow color on it, always did.

 

I've been doing 7-8k oil changes. Only reason I'm not doing 5k like others say is that fresh oil has detergents that wear out after a few thousand miles. There's talk that if you change the oil too often, the detergents in fresh oil isn't that good for the car.

 

Somehow I just can't accept that clean new oil is more harmful to the engine than the old used oil.

 

+1
Also thinking that

 

They do seem pretty reliable. 138k miles here, and haven't had to replace anything major. New thermostat, new blower motor, reconnect broken AIRMATIC pump wire, transmission fluid every 40k, oil every 17k, and various filters when they're due. So far more reliable than my Accord was.

 

probably the highest mileage ive seen on 550.
and it does seem that its holding up really good .... but oil 17k ? i think there is something wrong.

any tips/advices? since youve had it for a while im guessing

 

Nothing wrong with my oil, which is pretty much why I change it every 17k. Last report said I could go an ever longer interval.

Not really any tips I can think of. In general I think parking in a garage helps things hold up longer. I'm surprised at the number of folks who own an expensive car and park it outside.

 

never heard of 17k oil change intervals , but watever works right?

how long have you had the car for?
also i agree about garage thought

 

Most people set their oil change interval based on opinion. It doesn't really make any sense to me. It's bad for the environment and provides no real benefit to the car. Folks don't change brake fluid, transmission fluid, or brake pads at half the interval because it's "cheap insurance." I don't know what makes people focus on oil, except that it's something they kinda understand and can control. I don't think anyone who pampers a car even owns it long enough the benefit they expect.

I'm the second owner, I got it in 2013.

 

In Europe, they have 25k oil change intervals and there's plenty of Mobil 1 oils good for 15k. Most people in the US are afraid of that kind of interval. I think on the W211, it was originally 13k oil changes, but they lowered to 10k. Here there's a quick change oil place on every other corner so people got brain washed into doing oil changes every 3k. Just had mine done at a shop and they put a 5k sticker on even though I used Castrol 0w40 which should be good for the 10k.

 

You make me feel better so I'll stick to my 10k intervals. I started getting a little worried that the new trend was cutting it short.
Do you do mainly highways miles? I think there is one other person I saw on here besides for you with more miles on a 2010 550 then me.

 

Yes, I do pretty much highway miles (80%).

 

I can't agree with the last statement in first paragraph above. I am sure they are many people that drive cars for over 200,000 miles. FYI, I keep mine long enough to benefit. I drove my 1996 GMC Suburban 16 years and over 200,000 miles. My 2011 Genesis has over 201,000 miles on it. We have had the 2005 E500 since 2007 and it now has 170,000 miles on it. My daughter has a her 2005 Hyundai Santa Fe which she has put over 254,000 miles on. We drove an Acura to past 235,000 miles and Toyota to just under 300,000 miles.

 

It's good to hear that 550 holds up well. Hopefully, this will be my next ride.
