10W-40

10W-40 motor oil is a popular choice among car owners and mechanics because of its versatility and ability to perform in a wide range of temperatures. The "10W" refers to the oil's viscosity rating in colder temperatures, while the "40" represents its rating in hotter temperatures. This means that 10W-40 engine oil can provide sufficient protection to your engine in both cool winter mornings and hot summer afternoons.
