Milton 1002 High Performance Conventional Oil

Milton 1002 is a conventional oil designed for all oil-lubricated reciprocating air compressors. It provides wear and oxidation protection, helping to prevent sludge and carbon deposits. The 1-gallon size is convenient for smaller shops or maintenance budgets. Use as directed by your compressor manufacturer to preserve efficiency and reduce maintenance intervals.
Milton 1002-32 High Performance Conventional Oil

Milton’s 32-ounce variant mirrors the 1-gallon formula, offering solid protection against wear and sludge formation in oil-lubricated units. Its formulation targets oxidation resistance and carbon deposit control, supporting longer service life in daily workshop use and small-scale production tasks.
TRIAX Kompressor MV 100 SAE 30

TRIAX MV 100 SAE 30 is a full synthetic, industrial-grade oil engineered for rotary, vane, screw, and reciprocal compressors. Its high-temperature formulation delivers up to 1000% higher load-bearing capacity, a thick film that minimizes metal-to-metal contact, and a service life well beyond typical oils, reducing maintenance and downtime in demanding environments.
TRIAX Kompressor MV 46 / SAE 20

This full synthetic, multi-viscosity oil is designed for all-season performance—from arctic cold to hot summer days—while delivering over 20,000 hours of service life. It provides a robust, non-detergent formulation that safeguards bearings, reduces wear, and supports extended intervals between oil changes for commercial and industrial deployments.
4.5HP Portable 13 Gallons Oil-Lubricated Air Compressor Oil

Designed for oil-lubricated portable compressors, this unit supports up to 115 PSI and emphasizes long life, reliability, and safety. The oil-lubricated design helps reduce wear under high-demand use, making it suitable for projects like framing, bolting, and nail finishing, as well as inflation tasks.
3.5HP Ultra Quiet Oil-Lubricated Air Compressor Oil

This 10-gallon portable model uses oil-lubed mechanics for smoother, quieter operation. It features a 115 PSI maximum and a built-in regulator for precise control, suitable for hobby painting, light carpentry, and domestic projects where indoor use is common.
Mag 1 Air Compressor Oil 1 Gallon

Mag 1 oil blends refined base stocks with anti-foam agents to provide a long-lasting lubricant. It helps maintain smooth operation and can contribute to extending compressor life by reducing foaming and ensuring consistent film strength across duty cycles.
Buying Guide: Key Considerations For Oil-Lubricated Air Compressors
- Oil type: Conventional versus synthetic blends. Conventional oils are typically cheaper and suitable for many newer and older models, while synthetic blends offer better high-temperature stability and longer service life in demanding environments.
- Viscosity: Match the viscosity (SAE rating) to your climate and compressor design. Multi-viscosity formulas adapt across temperature ranges, reducing the need for different oil grades seasonally.
- Operating temperature: High-temp environments benefit from oils with strong film strength to protect bearings and valves from metal-to-metal contact.
- Detergents and additives: Non-detergent formulations minimize sludge formation; anti-foam and anti-oxidation additives help sustain pump efficiency and reduce deposits.
- Oil capacity and maintenance: Consider bottle size and how often you’ll perform oil changes. Some units require more frequent changes; others can run longer on premium oils.
- Compatibility: Always use oil recommended by the compressor manufacturer and verify viscosity and grade compatibility with your unit’s seals and metal components.
- Maintenance practices: Regular oil changes, air filter maintenance, and draining moisture from the tank extend compressor life and performance.
- Safety and storage: Store oil in a cool, dry place and dispose of used oil per local regulations to avoid environmental impact.
