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?
