Lubrication Systems Purposes of the Lubrication System

#1 – Minimize wear and power loss from friction

#2 – Acts a coolant

#4 – Absorbs shock between moving parts

#5 – Acts as a sealant between parts

#3 - Cleans

Lubrication Systems Properties of Oil

#1 – Viscosity – resistance to flow

#2 – Resistance to Carbon Formation

#3 – Corrosion and Rust Inhibitors

#4 – Foaming Resistance

#5 - Detergents

Lubrication Systems Viscosity and Service Ratings

Viscosity – the rate of flow !

Viscosity Ratings

Single Viscosity Oil SAE 5SAE 10SAE 15SAE 20

SAE 90SAE 100SAE 120

SAE - Standard of Automobile Engineers

Multi Viscosity OilSAE 5W - 30SAE 10W – 30SAE 15W – 40SAE 20W – 50

W – means wintergrade, calibrated at -18 C

Lubrication Systems Service Ratings

A rating based on the application of service which the oil is designed for !

Tires Purpose: - absorb minor road irregularities

- grip the roadTubeless vs Tube TiresTire ConstructionBias Ply Tires vs Radial TiresBelted Tires

Advantages- more weight / ply- good off road

Advantages- better cornering- better traction- run cooler- last longer- improved MPG- higher speeds (no tire squirm)
