i need to change my 2.8 a4's oil, but I still need some info before i do it. What else needs to be changed, like filters, etc. it doesnt have to be related to changing the oil, but something that i should do while i am at it. And what kind of oil is the absolute best?

 

you might want to consider changing the cabin filter too. There is no "best" oil really. These are Audi approved:

i hear mann is the best cabin filter, is this true?

 

yes it is the best oil filter too (it's oem).

 

whats the diff between the oil filter, and the cabin filter? are they easy to replace?

 

the oil filter filters the oil. The cabin filter filters the air before it enters the climate control system. Both are easy to replace if you've ever done an oil change before. The cabin filter is located on the passenger side behind the first firewall. Open the hood, look under the windshield. You will see a large plastic cover that goes under the windshield, remove the big black screws. It will pull out and you will see the place where the filter goes on the left. It's sort of a rectangle panel filter.

You may also want to change the engine air filter too.

 

I know everyone says mann oil filter are the best, but i use a cold k&n filter, and my oil stays cooler, just something ive noticed..

 

when u change ur oil, u always change the oil filter, and check other fluids.
