You want to do oil analysis like the professional diesel mechanics do.

Most people don't need to change their oil anywhere near as often as the manufacturer specifies. Especially for large diesel engines, it's often fine to run them 3x-5x the interval, but you should do oil analysis and find out, instead of just using the rule of thumb ones the manufacturer gives you.
