Properties of Oil
Oil is made in many different forms. To know
what oil you need may be difficult. LubeTrak cannot tell
you the best oil however, we can recommend what may work
best for your application.
Lubricating oil made from two parts:
The need to change oil is because the base oil gets contaminated.
Base oil does not break down. The additives get depleted
from picking up all the contamination.
Lubricating Oil Functions:
-
Friction Control -- Separates Moving
Surfaces
-
Wear Control -- Reduces Abrasive Wear
-
Corrosion Control -- Protects Surfaces
From Corrosive Substances
-
Temperature Control -- Absorbs and Transfers
Heat
-
Contamination Control -- Transports Particles
And Other Contaminants To Filters / Separators
There are two types of Mineral Oil Properties:
1. Paraffinic: Viscosity Index of 95-105, Applications
Include:
-
Crankcase Oils
-
Hydraulic Fluids
-
Turbine Oils
-
Gear Oils
-
Bearing Oils
2. Naphthenic: Viscosity Index of 30-70, Application
Include:
-
Locomotive
-
Engine Oils
-
Refrigerant Oils
-
Compressor Oils
Synthetic Lubricants Are Man Made Fluids:
-
Scientifically Designed Molecules
-
Molecules Have Identified Structures
-
Fluid Properties Are Very Predictable
-
Made By Polymerization (To Make Larger
Molecules)
-
Group ll And Group lll Oils
-
Higher Flash Point
-
Lower Pour Points
-
Lower Friction
-
High Shear Strength
ISO Contamination Code:
ISO 4406:87

Comparison Of Clean And Dirty Oil From An ISO Reading:
-
Clean: 14/12/10
-
Dirty: 21/17/14
We recommend an ISO count (Particle Count) On Your Hydraulic
Oils.
