10W30 Motor Oil

At low temperatures, 10W-30 oil has a viscosity similar to that of a 10-weight oil, which means that it is slightly thicker and flows less easily than a 5W-30 oil. This makes it suitable for use in moderate to cold weather, as it can still flow through the engine's lubrication system when the engine is cold. At high temperatures, the oil has a viscosity similar to that of a 30-weight oil, which means that it is thicker and provides good protection for the engine's internal components.

10W-30 motor oil is suitable for use in a wide range of vehicles, including passenger cars, trucks, and SUVs. It is particularly common in vehicles that operate in moderate to cold climates, as it is able to flow more easily when the engine is cold while still providing good protection at high temperatures. It is also commonly used in older vehicles that have looser tolerances and can tolerate a slightly thicker oil.
