Gear & Differential Oil

Hi ppl,

my car (e46 2002 318i) is at 70k miles and i am having the gear and differential oil changed, as many people on this forrum recommened.

I went to BMW and they said they do not sell this oil and i would have to bring it in to have it changed...(they must be joking).

i went to my own mechanic and asked him to change the 2 oils...he just called me and he said the gear and differential have life time oil stickers on them hence he doesnt want to change them.

he has not told me that if i want them changed, i will have to sign a disclaimer that any issues with the gear or differential later on, due to the oil change, will not be his fault.

I am happy with signing that, as i know changing the oil is only going to be a GOOD thing to do...but does anyone have any views regarding this?

thanks.

I used Redline when I changed mine. I've gone at least 50K since and no probs. Their website will tell you the proper weight to use. I've heard Royal Purple is good too.

I'm using mobil 1 synthetic. I doubt you really need to change it. Maybe if you had an LSD or something. I don't think that much can go wrong in an open diff (besides having a seal leak)

i recommend DIY. nothing easier than pulling a fill/drain plug, for the transmission at least. (my rear sway bar blocks one of the diff plugs )

btw, assuming its a manual.

Assuming a manual transmission, the BMW transmission fluid (Pentosin MTF2) is available from Pelican parts. BMW says the fluid lasts for life which may be true but the floating metal flecks don't go away. The first time I did this the bottom of my catch pan looked like Id been panning for steel so I'd be on the side of doing it. The DIY is easy if you've got the tools.

As for the differential (also an easy DIY if you have a stubby hex driver to get by the sway bar) any good 75W-90 gear oil works - I like Royal Purple. This one did not really show any wear when I changed it.

DIY. i did my fluids at 80k miles and it was smooth as butter. never really had any problems before the fluid change, but after you really notice the difference. i have an auto trans, i dropped the whole pan and put a new filter and new gasket. filled with redline fluid (dont have the weight right now) the diff was straight drain and fill. filled it with the purple stuff i fit about 6 quartz in the trans and 1 quart for the diff (i also used additive) came out to about $100 for all the parts and did it in less than 2 hours. im at 90k now and still running smooth. i plan on doing it every 30k (drain and fill)its too easy not to do it!

Just shy of 110K miles now. Did a major service ... oil changes ... cooling system overhaul ... spark plugs and tadaaaa ... UUC short shifter and DSSR ...

At this service I changed the 5-speed to Redline ATF D4 (don't use MTL!! It's too thick) and the rear diff to Redline 75W-80 GL-5 gear oil.
The difference in how much smoother and better the 5-speed shifts (especially when cold!) is UNBELIEVABLE!

Gear Oil

an update...my mechanic did finally refuse to change my gear oil (and differential)!

When i went to pick up my car, he said he couldn't find any oil for it and when he spoke to his suppliers, nor could they.

Infact, on the way to my mechanic, my taxi driver also said, don't change the gear oil, you never need to do that, unless major issues with the gear.

I called the Stealership today and they more or less said the same...don't change it if there is no problem and they didn't recommend it either. And if i insisted, they said 235 (155 labour).

Why is no one willing to change it? It is no that I am asking for free work to be carried out?!?!?

I admit there is no major issue with the grear, but its very stiff during a cold morning and isn't as smooth as it used to be when I bought the car about 4 years back.

I used Redline products for my tranny and diff. The dealer usually won't sell the oil as it's in large barrels they buy it in. I've heard of some dealerships selling it as a favor in smaller quantities, but most won't.
Yes, they are both listed as Lifetime fluids as part of BMW marketing claims and more likely due to the maintenence schedule they don't want to do for free. At 70K I'm sure you are fine. But if you decide to do yourself it's not that hard. But will need a handpump to fill it.

If you have a manual trans, just do it your self with Redline MTL and the diff should be Redline 75 90. It is super easy and will save you a few bucks.

If it is an auto trans, check the threads on that subject as I have heard mixed reviews.

Hi All,

As above mentioned by various of you, there does not seem to be a consensus as which Gear Oil I should use. The below 2 are the ones you mentioned.
- RED LINE ATF D4
- RED LINE MTL

Both of these are available at this website:
http://www.opieoils.co.uk/c-415-redl...atfs-mtfs.aspx

...but as my car is 5 Speed, Manual, 2002, 318i, N42, which one does everyone think is the most suitable?

Also, how many bottles would I require? (they appear to come in 0.9 Litre bottles)

many thanks.

I just bought the MTL for my 330i 5-speed. I'm changing it today so I can't give you any thumbs up or down yet.

I use Mobil 1 ATF in the manual transmission and Mobil 1 75W-90 gear oil in the diff. Mobil 1 synthetics are as good as any, readily available, and slightly cheaper than the boutique oils. Nothing wrong with Redline oil, but I don't see any advantage over Mobil 1.

right, I am about to embark on the gear oil change for my car when the snow clears up. It is a 318i, N42, Manual 5 Speed Gear.

I have more or less everything I need for the oil change, but still am not sure about what torque to use on the the nuts.

1) Can anyone with a similar car / gear and also who may have carried out the DIY please advise?
2) Also, why does the Torgue actually matter? Why not just tighten the nuts, so the oil doesnt leak out?

many thanks.
