1. 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

2. 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 Where does oil come from ? How is oil created ?

3. Lubrication Systems Viscosity and Service Ratings Viscosity – the rate of flow ! Viscosity Ratings Single Viscosity Oil SAE 5 SAE 10 SAE 15 SAE 20 SAE 90 SAE 100 SAE 120 SAE - Standard of Automobile Engineers Multi Viscosity Oil SAE 5W - 30 SAE 10W – 30 SAE 15W – 40 SAE 20W – 50 W – means wintergrade, calibrated at -18 C

4. Lubrication Systems Service Ratings A rating based on the application of service which the oil is designed for ! SA SB SC SD SE SJ SK SL Light Duty Heavy Duty

8. Tires Purpose: - absorb minor road irregularities - grip the road Tubeless 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)
