All BMW fluids: oils, brake fluid and coolants - w/BMW part numbers... You can see that BMW only sells the rear diff oil in 60L or larger (6,000L) sizes. lol http://www.bmwinformation.co.uk/dg/b...7/digi-pdf.pdf Castrol Deutschland... a listings of the special Castrol oils by car model and year. Also lists OCI (by BMW) and oil quanity! http://195.82.66.170/castrol/oilguid...15&range=15015 a online site for OE spec oils... http://www.fahrzeugoel24.de/index.ph..._from_store=de and I found this over at BTOG website referencing THIS DIY thread! lol http://www.bobistheoilguy.com/forums...Number=2127961 And here is a data sheet... but it is in Russian! lol This was the ONLY site I could find any data on the MTF oils. http://translate.google.de/translate...st%26id%3D4230 Dackel |

I also found this post on the M3 forum...
But this is in regards to the 1,200 mile service on an M3. It is also written in German, but its nice bc it references the BMW part numbers for the fluids. I still think using MTF-LT-4 is the way to go though, since that is what is listed in the parts dept pc. The main problem is when you go to order the rear diff oil thru the dealer... the smallest container it comes in is 60L drum. But in this post bellow he lists a 1L container for SAF-XJ 83 22 1 467 993 (one liter) I already have my oil... but its interesting never the less. Its also trange the read diff oil comes in a 1L bottle because I have only seen it in 500ml bottles over here. ??? Maybe that was a typo? http://translate.google.de/translate...p%3Ft%3D129886 Castrol MTF-LT-2 83 22 0309 031 (five liters) 83 22 0309 031 (fünf Liter) 83 22 0406 941 (half liter) 83 22 0406 941 (halber Liter) Castrol MTF-LT-3 Castrol MTF-LT-3 83 22 7533 818 (five liter) 83 22 7533 818 (fünf Liter) Differential - 1.1 liters, 1.2 quarts Differential - 1,1 Liter, 1,2 Liter SAF-XJ Synthetic Final Drive oil for Limited Slip Differential SAF-XJ Synthetische Final Drive Öl für Limited Slip Differential 83 22 1 470 080 (55 liter drum) 83 22 1 470 080 (55 Liter Fass) 83 22 1 467 993 (one liter) 83 22 1 467 993 (ein Liter) 83 22 2 282 583 SAF-XJ+ FM booster 83 22 2 282 583 SAF-XJ + FM-Booster Dackel |

If it's any help, from what I've been told the limited slip additives might not be such a big deal. I ran Red Line 75w90ns in the diff of my last bmw (no limited slip) because it doesn't have the friction modifiers. When it came time to change it again I checked with Red Line, and they told me the regular 75w90 would actually be a better match to use even in an open diff, as it'd likely run a little cooler.
The viscosity difference is really interesting though, that castrol being 75w-140 vs. the 75w90. |

Ls adds need only be added to prevent noise and chatter in LS diffs. The addition of LS adds in a finished product is more of a "value added" issue.
LS adds can harden the gearface as I've read, but I've not heard that gear lubes with FM adds run hotter - it should be the reverse. AFAIK, the 1 series uses an "electronic" LSD that strategically applies the brake to a spinning wheel. It is an open diff. BMW did have a TSB sometime back specifying XJ for all LSD models in all cars. However 90wt or XJ (which is 140) are acceptable for open diffs, as I recall. The funny thing with 90 wt lubes is this: every viscosity in the motor oil and gear oil system is actually a range of viscosities (measured as centistokes at 100C.). A few years back, API split up the 90wt gear oil range such that the lighter (lower visc) part retained the naming of 90, whereas the upper half of the range, which had butted up against the 140 range was relabeled as "110". So you can get a 75w-110, though they are not readily available just anywhere... IMO BMW made the XJ mandate to prevent overly light 90wt fluids from being used in diffs where a lot of power was to be transmitted (i.e. LSDs on the M cars) and film thickness may not be sufficient under heavy load. I'll need to review all thelinks above, but if a 90wt was recommended for a 135, I'd be careful in selection for as viscous of one as possible or a 110 or XJ, given the ready availability of torque at such low speeds. |

So depending upon how you read this, XJ and/or syn oil is right for all BMW diffs, so unless I read otherwise officially from BMW, 140 it is back there... If out of warranty and gas goes up to $4-5, a 110 may provide reasonably similar protection in all but extreme transient use, while providing 1% efficiency improvement. |

I am also wanting to change the rear end and transmission fluid in my manual 135i. I am thinking of going with redline fluids:
For the rear: For the trans: Has anyone used these fluids before? Any reason not to use these? Thanks! -Joe Last edited by joeo; 01-10-2011 at 12:48 AM.. Reason: manual |

I think it would be Ok. But for me IF anything were to fail while under the powertrain warranty... I don't want to give a BMW a reason to deny warranty coverage for my car. So... that is the reason why I will use BMW's LTF tranny oil and Castrol diff oil. Dackel |

I saw something on German TV this summer. It was on the TV version of Auto Motor und Sport - (magazine) on VOX channel. The show is called: Auto Mobil. They ran a spot on how the GM tranny that BMW uses... can does does fail after a few years of service. http://www.1addicts.com/forums/showt...+und+sport+vox I am not sure who makes the A/T trans in the 1er's. Even though BMW says it is a "lifetime" fluid... it is not. The show on VOX (featuring LENK trans repair shop) showed that even though BMW says it is a lifetime fluid... that really just means to BMW that "lifetime" is 100,000 kms. When and IF you change your A/T tranny fluid... you will also want to replace the valve body filter. The A/T holds over 9 Liters of fluid. But you won't get everything out bc of the torque convertor. So you might want to do two quick changes - close together (mileage wise). Dackel |

Redline says to use D6-ATF and 75W90, but it's looking like 75W140 is correct? Thanks! -Joe |

Wolfe - that Pdf is dated 11/2008. But it talked about the M1 model as in the ORIGINAL M1! So it has some age to it.
One thing is for sure: Castrol SAF-XJ is specially designed to work in M lsd's. It says that right on the Castrol bottle. In that Pdf it also says "normal" diffs should use: SAF-XO It also says these cars can be identified by a centeral fill oil plug on the diff. BUT... on a 135i the "fill hole" is an offset type? It sits to the right side. So... ? Perhaps, you can use SAF-XJ in non-lsd cars. But not the other way around. ? Or perhaps the 135i does indeed have a quasy LSD? Since I am almost 100% sure my parts guy said to use Castrol SAF-XJ. Perhaps I should go recheck this before I change the diff oil. Dackel |

UPDATE!!!!!!
So... I sent my German BMW Zentrum(dealer) an email asking them to recheck their info for which gear fluid is needed for my 135i. They now say that BMW says Castrol SAF-XO is needed for all non m-cars. SAF-XJ for M-models (bc of the LSD). Even though on the parts screen I know I saw SAF-XJ! lol So... I then contacted Castrol Deutschland's technical dept. They told me that... yes, SAF-OX is the oil for a 135i (and all non M-models) and SAF=XJ for M-models(bc of the LSD). But then I asked them why does all of Castrol's spec books say to use SAF-XJ in all of the BMW models. They wrote me back this: Herr xxxx, Many thanks for your email. SAF-XJ can be used in both sorts of differentials, with and without the need of a limited slip additive. SAF-XO is just for the use in differentials with normal lock applicable. So, with the use of SAF-XJ you will be on the safe side. With kind regards Deutsche Castrol Internet Service Center mailto:kundenservice@castrol.com http://www.castrol.de Fax 0800/ 999 27 26 ........... So... It IS safe to use Castrol SAF-XJ in our cars. I will use the gear oil I bought. The only thing is the thicker gear weight of the oil. I found some data tech specs online... and found out that the two oils (75w90 vs 75w140) are very close in specs.

Just did this same process (just the transmission - not the rear diff) on the 135i using Redline D6-ATF. Took some pictures along the way:

Nice write up joeo. I'm gunna change my transmission fluid once I hit 30K miles. Did you change the differential fluid too?

Yeah that is a great write-up. Any pics or explanation where you rested the car down on the jackstands and what you used between the car and the stand itself.

I didn't change the differential fluid - was going to save that for another day.
Still trying to come up with a good way to 'suck' all the old fluid out. I was thinking wet-dry vac! I just put the jackstands under the jack points on the sides of the car. BMW uses those plastic jack points. I didn't rest the car down on them, just put them there in case something horrible happened to the jack holding the back of the car up. -Joe |

You can also go back one page and look at my post: #61 & #62. Castrol SAF-XJ is backwards compatable for our diffs. It can also be used for M-cars. But my dealer said the diff calls for SAF-XO. I talked to Castrol Deutchland and they told me that SAF-XJ can be used where SAF-XO is specified. I will be using the SAF-XJ in my car soon. Soon as the weather gets bit warner to crawl under my car! Dackel |

Ok... as promissed... here is what I found on the end of my UUC oil drain plug. This is after about 7K kms of use. What I found was really just a fine metalic dust. Actually I was expecting more ferret metal particles - from my VW days. I think this just proves that frequent OCI has gotten rid of alot of metal particles from my engine. This was my fifth oil change in 24K miles(total). here is what I found.... UUC oil drain plug untouched - just removed from oil pan... a closer look - untouched... the silver stuff on the paper towel is the matal collected on the end of the magnetic drain plug. all cleaned up!
