As I have said here before, I do lots of LOOONNNG distance touring. The last trip was over 8,000 miles - towing a camper. I run an oil filter on the side cover and an air cleaner. I have temperature and oil pressure gauges (the middle main bearing has been pressurised to 25 psi). I do anything from 250 to 700 miles in a day. Oil is changed when the instruments tell me to.
I quickly learned the relationship between speed, temperature and oil pressure. When I see the oil pressure holding at a lower figure than the speed I was doing at whatever the temperature would normally produce, I change the oil. I generally get 3,000 to 4,000 miles out of a cheap 20W50 grade oil but that is reduced when I'm doing short trips.
