Exclamation 7G Tronic Plus + Motul ATF VI... will it blow???

Hello!
I bought a 2011 GLK300 with 110000 miles on the clock and I'm pretty sure the last transmission service wasn't done... so I'll do it rather sooner than later.
According to the VIN # the transmission part number is 722964 02 955648, so I belive it's a 7G Tronic Plus (correct me if I'm wrong).
I know the blue oil standard is MB 236.15 for that transmission model. Sadly I can't get the genuine MB oil over here (3rd world problems).
I'm thinking of buying Motul ATF VI... on the tech spec (motul.com/ca/en-US/products/atf-vi) it says:
MB 236.15 (except FE benefits)
Does anybody know what the "except FE benefits" means?
Thanks to all.
BR

I would not risk it. If you have a Mercedes dealer, just buy the OEM oil.

Thanks for your answer.
Over here the dealer is out of the question, also I think "go to a dealer" is way to common of an answer for all forum questions. Coming from other brands (audi and bmw) where the owner community is much more DIY oriented and owning a peformance shop myself, I will be looking to do as much work myself as posible on the GLK.
I know Liqui Moly ATF 1900 will work, but can't get that either (in my country only 1800 gets imported). The only available oil is Motul ATF VI... just need to be sure if it covers the spec in full.

I meant purchase the parts from the dealer. I am a DIY and big bimmer guy myself and whenever I due ATF changes on BMW transmission, I don't mess around with any other brand unless they have reach BMW certified approval.

The only other ATF I know that meets and exceeds (rec'iving certification from MB) is Liquid Moly. Try FCP Euro they may be able to ship internationally.

I've already called the dealer. They will only sell me the red fuild, not the newer blue one... also they want stupid money for it. My guess is that they do this to force me into getting it serviced there.
The problem with buying the oil overseas is that customs here won't allow petroleum/flamable fluids on regular mail (nor oils, car parts and a really long list of stuff I usually need). It has to be legally imported by a registered import company. We have really f*cked up customs policies here.
So... from all the ATF fluids I could find in the local market, the only one that might suit is the Motul ATF VI.

I think the FE references the “fuel efficient” aspect of the 236.15 blue fluid, and transmission.

My my only concern: MB says the blue isn’t backward compatible to red fluid units, but that Motul product is advertised as being right for units that use 236.14, and 236.15 fluids. If they aren’t backwards compatible, the Motul product may be making sacrifices in the formula to make it more universal.

As an aside: did your dealership refuse to sell you blue fluid *after* getting your vin number, or before?

And the results are in...

Fuchs along with Afton and Shell developed this at the time world's thinnest viscosity ATF .

Now for the red Motul .







As Fuchs was a co-developer its Fuchs Titan ATF 7134 FE is blue and approved by MB .

As for the viscosities ,

Motul ATF VI
40°C , 30.5 centiStokes
100°C , 6.10 centiStokes


​​​Fuchs Titan ATF 7134 FE
40°C , 18 centiStokes
100°C , 4.4 centiStokes

The verdict , the Motul you could , but I wouldn't.

Good info. If it is only the low viscocity fuel mileage aspect... I'm willing to go with it.
Called more than one dealer, a few didn't even ask me for the VIN. My guess is that they have limited amounts of MB fluid (also because I don't see it in sale on any local web site or shop).

Thanks!
So... it shouldn't do any harm... but it's not exactly the same. Using Motul will be like using the older red MB fluid.

Yes, the ones listed here: https://bevo.mercedes-benz.com/bevol...236.15_en.html
Sadly can't find any in the local market.




Thanks to all for the valuable input.
I will look around some more and hopefully I'll find a better and more compliant fluid.
I'm working now on the usual intake manifold problems (mine has a vacuum leak in one of the flappers axys) and getting the legal road inspection done (something like the UK's MOT and Germany's TUV).

I'm in Argentina and sadly there is a limiter offer on ATF fluid brands and versions.
I called more than one dealer and some didn't even bother to ask me for the VIN. My guess is that they have limiter quantities and are not willing to sell.

Looking at all the data, the Motul should work but will behave like the older red fluid... may do no harm but won't be as designed using the blue fluid.
I'll look around some more and see if I can find a better solution.

I found Motul ATF VI.... not the ATF236.15
Will try to make some calls and find out if they are even importing that one.
