Lubricating oils are substances used to reduce friction, wear, and heat between moving parts in engines and machinery, ensuring smooth and efficient operation.
Lubrication: Minimizes friction between surfacesCooling: Dissipates heat generated by moving partsCleaning: Removes dirt, sludge, and depositsProtection: Prevents rust, corrosion, and wearSealing: Helps seal gaps (e.g., in engines)
Types of Lubricating Oils
1. Mineral Oils
- Derived from crude oil
- Economical and widely used
2. Synthetic Oils
- Chemically engineered
- Superior performance and stability
3. Semi-Synthetic Oils
- Blend of mineral and synthetic
- Balanced cost and performance
