Engine oil is the lifeblood of your car’s engine. Without it, vehicles simply wouldn’t function. Motor oil protects your engine by lubricating parts which in turn minimizes heat and friction; the two biggest enemies of engine components.
As oil breaks down and becomes contaminated through normal use, it’s critical to follow the car manufacturer’s recommended oil change interval and replace the oil with the correct type. But what happens if you put the wrong oil in your car?
The motor oil in car engines has to function under various temperatures and pressures. For example, vehicles must endure cold weather during winter and hot weather during summer.
Oil has a harder time flowing in the cold and an easier time flowing in the summer. And if you’re towing a heavy load on top of that, it is even more work for the oil. This resistance to flow calculation is known as viscosity.
If you live in extremely hot or cold climates, you may need to use a slightly thicker or thinner oil but for the majority of owners, stick to what’s recommended.
