So, I'm wasting money if I changed it at 8k miles?
I think you have a lot of oil left at 8k. Do an oil analysis near the factory interval for peace of mind and see how wear is. That's what I did which made me confident to go further.

Just google Blackstone Laboratories; on the site request a test kit and they send it to you free. When you change your oil take a sample and send it back to them with a check for $28. In 2 weeks you will receive an email with your oil report. Hear is my last 5 Oil Analysis for reference.Who ans how do I get it send out?
If its black that just means that its doing its job and nothing more. The rules haven't necessarily changed but oils have come a long way in the last 20 years. Many of your big companies out there use an oil analysis to determine when to change the oil in their equipment. That's a hell of a lot cheaper than an 800 gal oil change in most cases.The AMSoil will certainly be black by the time the computer says its time to change. I don’t see why th rules have changed on this. Dirty oil means it is time to change
