Thanks for the order
Is this as good / better than the BMW stuff? I too want to change mine but have heard that only the BMW FM stuff is the way forward?
We've sold a lot of lot of the friction modifier and diff oil combination and it seems to be doing well.
Just purchased, thanks for the discount Opie!
Hi Oilman, I am also looking for gearbox oil for my 2002 SMG gearbox and was hoping you could point me in the right direction and the amount I would need.
Order Placed... Cheers Opie
[FONT=Arial, sans-serif]You need an MTF for the gearbox and I would go with the Redline MTL, Amsoil MTF or Fuchs Sintofluid.[/FONT]
Just done my diff oil with the FM, thanks for the discount
With the FM?? I thought only BMW sell the FM booster
I used the Red Line friction modifier. The diff oil from BMW stealers has the friction modifier stuff mixed in already.
Any offers on diff oil at the moment ..the friction one ideally
Here you go
Just trying to check on what amounts of oil I need to buy.
2. rear dif.
3. engine oil.
I know that this will be on here somewhere but I can't find it.
The gearbox and diff take somewhere between 1 and 2 litres each, so you need two bottles for each. The engine takes 5.5L.
So technically speaking the friction modifier just makes your LSD not as effective.
For a track car you want the clamping pressure so the fm stuff is best left out?
Was wondering this myself, Is the friction modifier put in by BMW just to prevent any noise from being generated by the diff? As people were complaining about it. It wasnt in from factory??
Lets say your diff has that noise that the modifier silences, Does that mean your diff is being damaged or is the noise no harm and just irritating??
Basically the friction modifier makes the LSD less effective, but less noisy and for most cars that's a good option, but perhaps not for the track ones. If the car is used on the road and track, I guess you need to decide whether you want the noise or the locking or perhaps use some modifier as a compromise.
So for example if you have a noisy diff it doesnt mean you actually have a damaged diff nor that its malfunctioning its just normal. And the modifier is just there to quieten it
Yep, that's it. Most LSDs (not just BMW ones) aren't great for low speed driving, but that's just the way they are.
