Rear Differential Fluid

n00bkiller944 · 06-13-2018, 03:48 PM

Getting ready to do a rear differential fluid change on my 14 328d. Anyone know what oil is recommended for the rear end? Any oil you guys recommend?

Thanks!

I put the Redline fluid... I can't remember if it was 75w-85 or 75w-90

What is the interval for changing the diff oil?

Thanks guys! Will update once completed!

Bump for update?

Used a mityvac pump to pump out the old fluid. Refilled with one bottle of this https://www.fcpeuro.com/products/gea...ly-99991754600

75w-140 is too thick per BMW specs. May be ok?
But they call for 75w-85 or thereabouts.

Good catch. I posted the incorrect link in my past post. I will go edit it. I used Liqui moly 75w -90. https://www.fcpeuro.com/products/gea...ly-99991754600

What Is the recommended interval for differential oil change?

auburnf30x · 04-13-2021, 12:25 PM

BMW says it's lifetime.

But I think 60k miles is a good time to get it done.

sspade · 04-13-2021, 01:23 PM

60k is the interval Ive been following as well.

I used the Redline / new plug kit from FCP Euro.

FCP Euro has a good YouTube series for F30 maintenance. Changing the rear diff fluid is one of them, they recommend OEM fluid.
