Using the right type of motor oil for your car engine is imperative for keeping it up and running. You cannot get a good return on investment if you don’t take care of your engine. Sure, many car owners take their vehicles to a mechanic for an oil change instead of doing it themselves, but that doesn’t give you an excuse to not educate yourself about what goes on inside your vehicle and have some information regarding the best motor oils for your car. This information is not redundant, and can always come in handy if you find yourself stranded and can’t avail the service of a mechanic.
Changing oil is one of the key car care tasks, which is why we will be doing a thorough 5w20 vs 5w30 comparison since those motor oils work best in both hot and cold temperatures. The Society of Automotive Engineers has a statistical code for differentiating between motor oils based on their viscosity characteristics, starting from low and going high: 0, 5, 10, 15, 20, 25, 30, 40, 50, and 60. The term ‘viscosity’ refers to a liquid’s resistance to travel.
