I have just bought a second bb4 (pics and full details to follow, when i get time). It has the m2b4 box.
I have 2 questions.
1) When i change the oil in it, is it same fill capacity as non lsd box1.9L.?
2) What is the correct oil for this, i use amsoil mtf in my non lsd box. But notice it says on bottle, not for use in lsd applications?
Cheers.
Tony.

AFAIK everyone uses amsoil. I've got amsoil ready to go in my M2B4

Ok, just wondered, as it does say that it is not suitable for lsd.

Amsoil is fine for OEM viscous LSD's. The gearbox takes 2 US quarts (1.9 L) for a gearbox fluid change. There are a few members who run Amsoil MTF in their M2B4's. I have driven Vanzep's and it feels great.

And as for the fill capacity, it should be about the same. At the end of the day you fill it till it comes to the top of the fill drain plug, so you'll know enough is enough as it'll be spilling onto the floor. :wink:
