Buying Guide

Match viscosity to equipment needs

Choose the correct SAE grade or ISO viscosity for your application—air compressors and gearboxes often require specific viscosities like MV 46/SAE 20 for proper film strength and pumpability

Prefer synthetic for high-temp or heavy use

Full-synthetic oils deliver better thermal stability and oxidation resistance for high-temperature compressor and industrial service, extending drain intervals in many cases

Select quenching oil by steel type

Use a quenching oil formulated for the metal you’re treating—products labeled for carbon steel provide predictable hardening and cooling curves for knife and heat-treat work

Pick coolant based on machining material

Water-based coolant concentrates designed for aluminum machining and flood cooling improve chip evacuation and surface finish compared with generic coolants

Consider auxiliary system components

Don’t overlook related parts like draft controls and fuel system accessories when selecting oils for heating systems; correct controls optimize combustion and heat delivery
