Switch From Diesel to Gas.

The diesel engines that work in our equipment, work in extremely dusty conditions. The engines will typically be going through about 25 gallons of fuel per hour. A Cat C13 for instance holds about 34 liters of oil. Depending on the manufacturer oil change intervals are recommended at anywhere from 250 - 600 hours of operation (and they are not specifying synthetic). So even at 250 hours the oil is changed every 6250 gallons of fuel which is every 184 gallons of fuel per liter of engine oil capacity. If I applied this line of logic to my Ford which typically burns about 4 gallons of fuel per hour I would be changing the oil every 640 hours or about every 25,000 miles of operation. I use synthetic and change it every 15000 miles.
