hint: Na is always 9 from that lab, it seems.

Looks like a great analysis. Shouldn't be a problem to run it out to 20-25k kms with only appropriate make-up oil added as necessary.

Canadian? And not running Esso XD-3 0W-30? Your wallet must be hatin you

Gas is too pricey here for non energy conserving oils. I'd buy XD-3 0w20 if they made it.

I don't think I could have run this oil any further. The TBN is low, the viscosity is way down. Probably a more robust oil would do better. I don't see many good reports with Mobil 1 and mine is not an exception. I was thinking of trying the XD-3 Extra Diesel oil but I doubt that it's a wise choice for a high RPM Honda engine.

You have lots of TBN left. I don't have a lot of confidence in that viscosity or else there is fuel dilution (which they missed) :shrug) But anyway. I don't think this is a bad report.
