RDU and FDU UOA with particle counts. Replacement fluid used Castrol TranSynd-668. This is the factory fill with approximately 23K miles on the oil and plan to change and take another sample in 30K miles to see if 668 is a good alternative fluid for the drive units.

See, I told you BITOG wouldn't become obsolete!
Dexron IV? What's that. And what's the point of this? This oil isn't contaminated with combustion particles. It doesn't even have friction material like a transmission. Seems like a waste of money on the analysis and the oil change. Don't think Tesla has an oil change requirement for this.
Apparently someone doesn't like data LOL
Anyways, In my experience front diffs experience less wear & tear in a rear wheel drive application. I'm not certain on Front wheel drives but perhaps it wears more in front diffs if front wheel drive. Don't know but it appears this is a rear wheel drive & front has about half the wear particles & less than 1/3 of the wear as the rear. Interesting data to see. Thanks for sharing.
If I'm not mistaken isn't the tesla drive unit really just a differential since it's a single speed reduction unit with nothing fancy which I think is really great. This single speed unit should be able to take any atf, there's no clutch. The porsche taycan however does have a dog clutch, shift actuator, multi plate clutch so that can't take just any atf since the clutch could slip and is a very big reason for me to dislike it since it's unnecessary and adds so much more complexity and cost in both buying and owning long term. Tesla is still more efficient and as fast. Still don't see the logic of an ev multi speed unit. I think porsche was just trying too hard to look different and more "advanced" to set themselves apart.
