20W50 Motor Oil

At high temperatures, the oil has a viscosity similar to that of a 50-weight oil, which means that it is even thicker and provides excellent protection for the engine's internal components. It is often used in vehicles that operate in warm to hot climates, as it provides excellent protection at high temperatures while still flowing relatively easily when the engine is cold. It is also commonly used in older vehicles that have looser tolerances and can tolerate a thicker oil. The "20W" in the oil's name refers to its low-temperature viscosity rating, while the "50" refers to its high-temperature viscosity rating.
