Sorry, correct me if I read it wrong, but your post came off as: Hey, I ran my car way over the service recommended limit, almost twice as long as recommended and I even used non recommended oil, (and possibly a suggestion of using a cheap filter), now I want to know if I can use a cheap filter, and I don't want to pay for a recommended service, but my oil is sludgy and my car is making a racket noise, and now I want to use Castrol 10W40.
How do I get out of this without spending money or using recommended parts and lubricants?

Now you are saying the dealer serviced your car and used mobil! 5W30, but at first, you came off as saying you saw no need to get the recommended "stealeship" service.
It's just not adding up.

(Independents) won't do a B- service under $300+.
it just sounded like you want to run the tar out of your car and don't want to put any money into it for suggested service, that's all.
A service B- is much more than just an oil change, and mass airflow sensors are not cheap when they get trashed from dirty air filters.
The service intervals give the tech a chance not only to replace maintenance items, but also gives them a chance to find and correct problems that may be showing themselves to keep you from having major repairs in the future if left unnoticed that's all.

If I read it wrong, sorry, just trying to give a little constructive criticism from someone who see's this every day, and has to educate customers on a daily basis that still don't listen and think all you want to do is take their money.

You may not be one of them, but one of them may be lurking around, but you did post your question to get educated by other drivers and to get their opinions.
What better than to get opinions from the experts who work on them every day and can give you the best possible recommendations other than hearing opinions from sooth sayers that run marvel mystery oil in their cars?

Reminds me a bit of my father-inlaw.
He used to run dino oil in his car for 10 k miles, drain it & use it in his farm tractor, because it still " looked good ", ..........until he blew it up.

All I'm saying is that if you want your mercedes to last, keep it serviced with recommended parts, lubricants and certified M/B techs.

If you own the car because it has a star on the hood and you just have it to look cool for the lonely, single mom's and get you car serviced at jiffy lube at twice the recommended service shedule, you're asking for trouble.

Sorry no star on the hood, and i look better out of the car then in it and single mom's???? sorry I'm taken... "iffy lube"... now that's a joke.

Lots of good information in this thread concerning maintenance and oil changing habits. I happen to fall into the "change oil and filter more often" category. My 2001 SLK230 has the FSS service system. With my driving habits, it takes 13,000 miles for the FSS indicator to turn on. Since I drive 6,000 miles per year, I don't want to go through 2 summers and 2 winters on the same oil and filter. So, I change my oil and filter every 6,500 miles using Mobil 1 0w-40 & MB Oil Filters.

My '93 190E 2.3 gets a new MB filter and Castrol GTX every 3,750 miles instead of the recommended 7,500 miles since I bought the car new. I don't know if the next owner of my cars will appreciate my attention to oil change habits, but I prefer to do it for my own piece of mind. I also replace my air filters in both cars at half the recommended intervals.

I always thought that if I was the type of car owner that traded cars every 3 to 4 years, then it wouldn't matter. I'm sure you could drive a new car 50,000 miles without an oil change, then change the oil and filter and no one would know when you sold it or traded it in.

It ceases to amaze me that people purchase very expensive cars and then complain about a cheap oil and filter change!

I change oils and filters on my fleet every 6 months or 5000 kms and 20 years later they still run like new - as they say "Change it hot and change it often".

For some , it is all about image to impress while neglecting the image in which they propel themselves.
Might as well just walk around in an expensive suit kicking yourself in the balls.
