Common Quincy Maintenance Intervals
| Interval | Maintenance Task | Why It Matters |
|---|---|---|
| Daily / Before Use | Check oil level, drain tank moisture, inspect for leaks, listen for abnormal noise. | Helps prevent oil starvation, corrosion, pressure loss, and unexpected downtime. |
| Weekly | Inspect belts, guards, fittings, vibration, and air intake condition. | Helps identify wear or restriction before it becomes a larger service issue. |
| Monthly | Review filter condition, fasteners, safety valve operation, and service records. | Supports reliability and helps maintain warranty documentation. |
| Scheduled Oil Service | Change compressor oil or synthetic fluid according to model, use, and environment. | Proper lubrication protects the pump, bearings, rings, and internal components. |
| Scheduled Filter Service | Replace or clean air filters and oil filters where applicable. | Clean filters improve airflow, lubrication cleanliness, and compressor efficiency. |
Quincy Oil Type and Fluid Guidance
Quincy compressor oil and fluid requirements vary by compressor family. Using the correct oil or synthetic fluid helps protect the pump and supports long-term compressor reliability.
Single-Stage / Smaller QT
Quincy 40-Weight Compressor Oil
EWK-1, EWK-2, and EWK-3 include Quincy 40-weight compressor oil for supported single-stage, QT-54, QT-5, and QT-7.5 applications.
Larger QT
Quin-Cip D Synthetic Fluid
QT-10 and QT-15 EWK kits include Quin-Cip D synthetic compressor lubricant or fluid for scheduled maintenance.
QP Series
Pressure-Lubricated Service
QP-series EWK kits include Quin-Cip D synthetic fluid and oil filters because these compressors use pressure-lubricated pump designs.
When Should Quincy EWK Kits Be Used?
Quincy EWK kits are warranty and maintenance service kits. They are commonly purchased with qualifying compressors to support Quincy extended warranty requirements, but the components can also support scheduled service when the kit contents match the compressor model and maintenance requirements.
Use EWK Kits for Warranty Support
- Purchased with a qualifying Quincy compressor
- Registered according to Quincy requirements
- Used to support No Bull Extended Warranty coverage
- Helps document OEM maintenance components
Use EWK Kits for Scheduled Maintenance

Quincy Air Compressor Maintenance FAQs
How often should a Quincy air compressor be serviced?
Quincy compressors should be inspected regularly and serviced according to the compressor model, operating hours, environment, and oil type. Always follow the maintenance schedule in your Quincy documentation.
What oil does a Quincy air compressor use?
Oil type depends on the Quincy compressor model. Some single-stage and QT models use Quincy 40-weight compressor oil, while larger QT and QP-series compressors may use Quin-Cip D synthetic fluid.
How often should Quincy compressor oil be changed?
Oil change intervals vary by model, oil type, runtime, and operating conditions. Check your Quincy manual and service records before ordering oil or maintenance kits.
When should Quincy compressor air filters be replaced?
Air filters should be inspected regularly and replaced when dirty, restricted, damaged, or due according to the maintenance schedule. Dirty filters can reduce airflow and increase compressor stress.

Quincy QP-series compressors use pressure-lubricated pump designs that require oil filtration. QP-series EWK kits include oil filters to help maintain lubricant cleanliness and protect internal components.
Can Quincy EWK kits be used for service after the warranty period?
Yes. Quincy EWK kits can be used for scheduled maintenance after the initial warranty period when the included oil, synthetic fluid, filters, and service components match your compressor’s maintenance requirements.
Which Quincy EWK kit do I need?
The correct Quincy EWK kit depends on your compressor model and series. Single-stage compressors use EWK-1, QT-54 uses EWK-2, QT-5 and QT-7.5 use EWK-3, QT-10 uses EWK-4, QT-15 uses EWK-5, QP-5 and QP-7.5 use EWK-6, QP-10 uses EWK-7, and QP-15 uses EWK-8.
