Blackstone Labs Oil Reports
I sent my oil to Blackstone for the first time. Everything looks okay. Does anyone have any input?
I had my engine, differential, and transmission done.

I'm disappointed that they recommended to extend the transmission drain interval to 20K. The viscosity is too low, like 10wt. Honda MTF shears down way too quickly. I'm not sure if its due to the oil pump, but I have had it shear quickly too. Are your shifts smooth now with the new fluid?
Feel free to compare with mine.

I would say the Iron and Lead ppm count could use some improvement with shorter intervals, but they aren't bad.

I think the MTF report was fine. I'm not too sure it is shearing that much, as it appears to be very thin from the start (VOA) now. I'll have to find the VOA I saw recently.
The Amsoil (ASL?) was fantastic. I don't know where the Tin is coming from though. I've never seen a UOA with Tin from a F22. Sometimes these wear metals show up in a VOA though, which means it was a storage or manufacturing contaminant. Keep an eye on your next UOA to see if it increases.
The gear oil (LE607) UOA looks OK, but I suspect that this was your first fill of LE607 and there was some residual OEM fill oil and break-in wear metals to take the Ni higher than usual. The Fe really isn't too bad though. The S2000 differential is the only one that I've seen throw so much Ni, regardless of oil grade or brand.
Many thanks for posting these UOA's!

Here is a VOA of Honda MTF, most likely not the improved version.

I still do. You can either search for something that last longer or change it more often. The shifting feels great and the wear looks good if you change it often, like 10K.
I'm not sure whats going on at Honda. Whats the recommendation, 30K for trans? I guess they would not care because by the time you drop the oil for the second time your warranty is up anyway.

I don't plan to run it more than 10k, so I won't be able to answer that question, but I do plan to run a UAO on it
with that said, it's pretty straightforward logic to believe a GL-4 rated gear lube is going to be more resistant to shear than a reformulated engine oil
I'm sure if you change Honda MTF every 5k, it's fine
