Why is the oil in my BUSCH Water Pump black?
- MmonroemelanieJul 26, 2025
If the oil in your BUSCH Water Pump is black, it's likely because the oil change intervals are too long or the oil has overheated. To resolve this, drain the old oil and fill in new oil. If the oil life is consistently short, consider using oil with better heat resistance or retrofitting cooling.
