Does anybody use Motul Gear Competition 75W140
I'm thinking about changing out my diff fluid sometime soon and am doing research on which product to put in. I know Castrol is the oem fluid. It looks like the Gear Competition from Motul has the same specs and has friction modifiers already added plus is less costly and easier to find than SAF-XJ.
Let me know what you guys use and if anybody uses Motul. |

I just changed mine with Severe GearŪ 75W-140. I don't notice any different but the car only have about 29K miles. The OEM fluid was somewhat brown when i drained it. Don't have any experience with Motul Gear oil.
