Oil intervals running local?

[jimeneztrans84]

For the past 3 months I've been running local freight. Maybe anywhere from 10 to 45 mile one way. I used to do my oil changes between 11-12k when running out of state. But now I'm running local and have a wet kit installed in my truck to idle at 9,000 rpm to unload walking floor trailers. I just did my oil change at 10k. Does that sound about right or maybe do it at 8k? Took me 3 months to get 10k.
