1. Understanding Engine Oils
What is Engine Oil?
Engine oil does more than just lubricate—it’s what keeps your engine alive and kicking. In my book, engine oil is the unsung hero of your car, quietly making sure everything runs without a hitch. It reduces wear on moving parts, cleans the engine, inhibits corrosion, improves sealing, and carries away heat—functions that are essential to keeping your vehicle in top shape.
The Role of Engine Oil in Vehicle Performance
- Lubrication: Reduces friction between moving parts, preventing wear and tear. I’ve noticed a real difference in engine noise and smoothness when using the right oil.
