E60 Differential Oil Change is Easy!

Based on the color of the oil and the content of the Blackstone report, this change was way past due. The differential had no leaks, and thankfully, wasn’t making any noise. This is one thing that you need to check when buying an M5, as a replacement can be costly. 

The only thing you have to be careful about is using the right torque for the plugs. There are two different types: one with a washer and one with an o-ring. It’s only a 5NM difference, so it’s not the end of the world. 

The oil change kit came from FCP Euro, and interestingly, it had a Mercedes sticker on the bottle. I guess if it’s good stuff, it’s good stuff 🙂

Don’t delay, change the oil on your BMW E60 M5 V10 Differential today!
