I'm also using Rotella T6 but I have 1/10th your mileage. I have had excellent results with Rotella in our motorhome which is why we switched.

IIRC from the threads where oil analysis was posted, 7500 was generally found to be a good interval. I'm going 6000 myself, but I work my engine pretty hard.

oil change interval

I use a vibration hour meter and keep track of how many hours the engine is run, not the miles covered. Better metric.

10,000 miles divided by 50 mph, my best guess of your average road speed, equals 200 hours.

As my average speed is more like 40, oil change will happen at around 6-7000 miles.

Using Castrol Edge 5w-30, (gold bottle) runs great.

5K Club

I'm with the guys in the 5k club for changing oil, 10k is a little long between oil changes and doesn't fit within my comfort zone.
Comon, 3.5qts of oil is no big deal, my beer tab is more than
JMO, your mileage may vary.

I use Royal Purple 5w30 and their filters and change the oil about 7-8k miles.
