Oil is crucial for any engine: it cleans, lubricates and cools all the moving parts to keep them working as they should and reduces wear and tear. It's available in a range of different types: mineral oil is the most affordable, while synthetic and semi-synthetic oil contains scientifically-developed additives that improve performance. Engine oil is also graded by its viscosity at different temperatures: 10W40 engine oil, is a multigrade oil that's rated ten for viscosity in cold temperatures and 40 at engine running temperature. Generally, the lower each number, the thinner and less viscous the oil. As any mechanic will tell you, never skimp on engine oil – it really is the lifeblood of your engine!
