Anyone Used Non-MB or Shell DCT Fluid?

I'm with Acta on not using anything other than MB or Shell transmission fluid, but just out of interest, has anyone used another brand like Liqui Moly, Pentosin, Redline, etc? Would love to know if the DCT felt or behaved any differently after doing the drain and fill with any brand other than MB or Shell.

Hi Enj,

OK, after my long diatribe about only using the factory recommended fluids in the transaxle. I did have the same problem as you and everyone else. I will admit I experimented with Motul Multi DCTF. It has been in my DCT for almost a year now. It is the one in the other thread where I showed the application sheet and Motul specifies compatibility with MB 236.25. I cannot report any problems. I don't track my car.

I do have some pretty aggressive sessions on the road, and I do get groceries with my car alot. STILL, I don't recommend it because I have no knowledge in petroleum chemistry and no way to validate this stuff will absolutely do the job. After ONLY almost a year, I STILL have my fingers crossed, but I cannot cross anyone else's fingers for them so I still have to caveat emptor you on this one.

I fought saying this online in the other threads. I know it sounds like double speak, but do not want any doubt I do not recommend this.

I'm with you om all of that. I just wish that I was able to get my hands on the non-dealer amount of the proper fluid. I literally can't find anything in this country.

In case someone will need the oil I have 17 liters of Spirax S5 ATE and 13 liters of TF DCT F3. Available for pick up in OC, California or I can ship at your expense. $25/liter

there should be a reason why MB didn't approve any other brands except shell. i wouldnt risk tbh.

Ordered DCT Mercedes Oil, came as shell. Looks like there is no point to pay more if it comes same.

You may be able to find other brands which claim their oil meet the specs but only the shell is officially approved by Mercedes. Source:

@artim808 - Exceptional depth of knowledge - a true gentleman and scholar.
Thank you so much.

For other interested parties - He still has some of these hard to find Getrag/Magna Trans fluids remaining.
