    Hi, Detane.

    I recently read through your thread about the differential oil on the W163 chassis. I have a 2002 ML320. You have argued that 75W-90 oil is good. I almost got the same grade oil today. But after browsing for what felt like the entire Internet, I have come to understand that there is a hot debate about which oil to use, the factory 85W-90 or 75W-90. Right now, I am leaning toward 75W-90 because it's easier to find. 85W-90 is almost impossible. If you do recommend 75W-90, what are the specific advantages of it? From using it, have you noticed any differences? And what brand would you recommend, or are all brands the same? I would truly be obliged if you could give me some insight.

    Thank you,

    I greatly appreciate all your DIYs! It takes ignorance out of decision making and enpowers ML owners. I don't know how to thank you enough!!!
