1. Engine oil
This is the lubricant that reduces friction between different engine parts. It aids in heat dispersion as well. The oil absorbs the heat generated by the engine combustion chambers and so it prevents overheating. Besides, oil prevents corrosion, rusting and damage of important engine components. Given the role played by oil in the functioning of the engine, you should regularly check its level. Do not forget to top it up using the correct grade of oil in accordance with the manufacturer’s specifications. When topping up, don’t go beyond the recommended level.
