Yeah I’m not worried about mine. 5k in two years. I might dump it this winter but I don’t think it’s needed. Your point is correct in it might be an indicator if something is not right…

Wow, those Amazon prices have gone up. I got mine at $14 bottle a month ago, and I thought that was outrageous.

I actually had my oil and differential fluid changed yesterday on my 22 ZL1 and the tech said the oil looked new but the diff fluid looked kind of gray. I had 1300 miles on it when it was changed. Just for reference I had the differential fluid changed on my C7 Z51 at about 10k and the tech said the fluid was gray also.
