Just about to change mine again. Wanted to get an update and see what everyone else is running currently. Oil Brand and weight. Thanks!

 

Mobil-1 0w40 synthetic.

 

Same here.

 

Ask for the Mobil 1, 0W-40 Synthetic, European Blend.

 

I used Mobil-1 0W-40 as well.

 

Same thing I'm currently running. Heard of some people running Mobil 1 0-20w as recommended in the SLS. Was wondering if anyone was running anything besides the 0-40w European blend?

 

There are other manufacturers oils you could run, as long as it meets Mercedes Spec.
Castrol comes to mind. I personally stick with Mobil 1

 

Really? Im no oil expert but isnt 0W20 pretty thin to run on the SLS? Plus I would imagine you would have to change it sooner then thicker oil.

Some guys are running MOTUL 8100 5W-40. Oils that are Mercedes 229.5 approved are ok to run in the C63.
I say stick with Mobil 1.

 

Thanks guys. Probably will be sticking with 0-40w euro blend I've been using.
More input is certainly welcome.

 

no one is using 5-40?

 

I am on my last fill of ESP 5W-40...the dealer is now using 0W-40 which makes more sense and I am happy about that. Hopefully I'm going to strike a deal with my SA so I can begin using this oil though:

Another oil question...lol! This subject has been discussed on about every motor powered vehicle forum.

Here is what I know without getting into the MSDS sheets to determine "Group". The important items to look for are Viscosity Index and flash point. Pour point is also important but since I live in California its not that critical.

SLS(229.5) calls for;
Mobil 1 SuperSyn 5/50... / VI-153/ Flash Point -236/ Ash1.2

Other MB's
Mobil 1- 0/40.... VI-185 / Flash Point -230/ Ash1.3
Mobil 1- 15/50.... VI-160 / Flash Point -232/ Ash1.21

In a nutshell....The higher Flash Point is important to reduce burn off while Viscosity Index is indicative of viscosity change with temperature. Obviously the higher the better. These are the numbers I look for.......so currently I have switched to Mobil1 15/50 simply for the slightly higher weight and flash point. However the 0/40 has the highest VI.

 

motul x-max 5w-40

 

motul 300v flash point is 450*

 

Lubro Moly 5w-40. Our winters are not that extreme to run 0-40. According to my service rep and independent tech.

 

There is also Castrol 5-50w and BMW has a special oil 0-60w I believe.

 

Mobil 1

mobil 1 0 40 for my C55 it loves it.

 

0w-40 in my benzos

 

I put Mobile 1 5w-40, is it bad??

 

This what you are supposed to run in the M156.

I run it too. They haven't used 0w40 in this engine in a few years now. Maybe some dealers haven't got the memo?

 

Alright thanks

But I don't understand, when I check on their website, they're saying that 5w-40 is for diesel trucks: http://www.mobiloil.com/USA-English/...uck_5W-40.aspx

I didn't keep the empty bottles of the oil but I'm pretty sure it was 5W-40.. and it was a green bottle

 

MOTUL 8100 5W-40

 

As of this year, 2012, MB is still recommending 0w-40 and 5w-40 for the M156. This info is from the STAR TekInfo website.
