Mali site with 8 excavators: service by hours or by condition?

Eight 20-25 t machines on two shifts, 16 hours a day in heavy dust.
The maker says 500 hours between oil changes; our samples start alarming at 380.
We are thinking of standardising at 300 hours but worry about cost. How do others balance it?

With oil analysis, follow the data instead of one blanket rule: air filters on differential pressure, oil at 350 hours.

We run two tiers: 300 hours for primary machines, 400 for standby. Cost stays under control.

Bulk buying oil and filters cuts cost, but do not save on filters: one bad sample puts the whole machine at risk.
