Oil Change and Differential Fluid

[S_CDSM5]

Have an oil change kit from an F10 M5/M6. Anyone know if 5W-40 can be used on the 650i? Also have the diff fluid change kit from ECS tuning that comes with 1L of Castrol 75W-140. Are the Diff bolts the same on the 650i as the M5/M6? If so, can i use 75W-140? Thanks!

You might have better luck posting in the non-M section. Guys with the car you want to use it in will have more experience (potentially) with crossing over components.

You could also search for products for sale for the 650 and see if you get the same results.
