Does Mobil expect everyone to do used oil analysis?
It's likely good for more than 15k IMO. When Mobil rates the oil I think they have to be somewhat on the conservative side since it's not for a single application.
In Canada Mobil 1 Extended Performance is rated at 12k instead of 15k. So there appears to be an adjustment for severe service based on climate but not as large as some people claim and that you need to do 300 mile trips every day.
