Taking off oil filter cap
 

I have a 04 E320 and the oil filter cap will not budge.
First tries i did by hand. Do I need to use something more?
It being plastic I did not want to force it.
I will be changing my own oil in the next month and wanted to get a head's up

Also, I noticed Peach parts has 5W40 synthetic oil and not the Euro blend this car calls for.
Is that a dealer only oil???

OK, my statement about the oil was regarding Allparts and not peach.

However, i still am curious if anyone knows a good place to get that Euro blend oil?

For the oil cap, I use a sliding jaw wrench with a shop towel to protect the plastic of the cap.

For oil, I'm assuming you mean Mobil 1 0W40. You can get this at most auto parts stores, as well as online (eg Amazon).

They don't carry it at Advance Discount Auto parts which is why I asked.

Amazon carries it??? Now that is rich!!

I saw there were 3 filters listed at Autopartsexpress.
Mann
Hengst
Mahle

All differently priced. Is there any difference in quality?

Plus there is a listing for a whole kit. Is that something that should be done at particular intervals??

I've only ever used Mann and Hengst filters, but I believe all 3 are OE for at least some models. Not sure what the kit refers to, usually I get the required replacement o-rings in the box with the filter only.

Here is the kit description

Filter Assembly: Fleece Filter Mann 718/5x (OE), w/ Cap, Support, Seal Rings;Contains Filter, Top Cover, Support and 4 O-rings;Packing Size: PIECE;

It has all the assembly so i was wondering if at a certain mileage or year this is a required change out

Big adjustable wrench works for me with the oil caps, seems like no matter what you do it glues it self to the valve cover. Even keep a spare just incase i break it, plastic + age + heat =fragile when forced.

My guess is that it is in case you break the plastic bits when you're doing your filter change. It does look like a lot of plastic, and I'm sure at some point you'll probably break something off as the car ages and the plastic gets old and brittle. I would get just the filter kits for now. I guess you could also buy the assembly and just keep it around so you don't have to wait for one to come in when the original breaks.

Glad it's not just me that was experiencing that -:)

MB dealers sell/used to sell a large socket to fit the oil filter cap. Best to use the proper tool than risk damaging/destroying the oil filter cap.

Oh whoops, I misread that.

I thought he meant oil FILLER cap, not oil FILTER cap.

For the filter cap I use the MB socket tool as well. Sorry. :)

The local Wal-Mart here had 0W40 Mobil 1 229.5 Oil the last time I was in there looking around AND the price was really good AIR $6.20 or so a quart. It was in the new Mobil 1 Bottles also. They had Fram filters for about $11 (with the O rings in the box).

They did not have it at the one I checked but there is another one I can check.
maybe I can get them to get it in if it is in their system computers.

I saw that tool poking around online but can't seem to remember where now.

Yes, use the special tool. Then you can apply the proper torque when reinstalling as well.

Acceptable Mobil 1 oils are

European Formula 0W-40 (229.5)

Formula M ESP 5W-40 (229.51) made for diesels but works in all

I would rather use an old sock than Fram filters, The worst fu**ing piece of s**t filters ever made. Hengst is my first choice.
