What type of weight and brand are you guys using for non LSD diff?

The owner manual show 75W-140 Hypoid oil but I read this weight is for LSD diff and could be a typo. My 07 E63 does not have LSD.

Also I have 2 bottles of Royal Purple 75W-140 in my garage, can I use this type of oil?

TIA

Royal purple will be fine. That's what I have in mine right now

The typo in this document is to NOT indicate the E63 P30 LSD with a dot indicator for the 75W-140.

It does clearly show all other E class to use specification 235.7 which you can find here.

All of this was hashed out on the forum way back in early 2008.

What confused me is in the 07-09 E63's owner manual they all listed something different.

My question is can I use 75W-140 weight in my E63 for non-LSD diff??

Your car came with the Mercedes 85W-90 lube, which you can buy from Mercedes.

I have had the Royal Purple 75-140 in my little C55 since January, and it runs great. It will work just fine for your E63.

I have had bad experience with syn diff lubes in the past resulting in heavy gear wear. I plan to stay with conventional 90W exclusive of LSD.

I went to the dealership last night to find out what oil weight MB technician put in the E63 and they show me 3 pints size bottle of MB diff oil 75W-140, about $18 each X 3. They told me all W211 E63 non-LSD use this weight. So I did not buy the oil but use the RP 75W-140 which I have 2 qt of it at home.

For future reference all W211 E63 non-LSD use 75W-140 weight.

No. The Mercedes web site information I sent above clearly shows it is not. I also sent a link to a "Approved Service Products 2007" that show this as well.
Also, when I first went to do the LSD oil change at 2kmiles, they gave me the gear lube 85w-90, which is correct for non-LSD E class.

Gents, you have seen my DIYs. I usually have this down right and I have been using the MB fluids page for 3years now. Of course that's my ego talking and it drives me crazy the amount of inaccurate information there is on this forum.

As for using the Royal Purple... I also anticipate it will work just fine for you, so no worries.

Jon you are spot on.

I went through this exercise after I had Quaife done. Non LSD cars came with the standard 85W-90 gear lube. P30 cars use the Castrol 75-140 lube.

I originally refilled with the 85W-90 lube after doing Quaife, but am currently running the MB spec Castrol 75-140 lube in my 63, per my dealer tech's recommendation, but honestly do not notice any difference.

Either lube will be just fine in the non LSD diff, as will the Royal Purple. Don't sweat it.

So?? how do I find on my car the diff ratio and if it is LSD or not?

Jon2007E63P30

Ask your dealer to print out your car options from the VIN number you provide them.

Given the car you list you drive, it is not an LSD. Not sure how to get the gear ratio.

Bringing this back from the dead. Is anyone running lightweight shockproof? I do have a quaife.

Muahahaha, trying RP 75w140 this weekend. Will report back on the results.
