What do oil grades mean?
5w 30 Synthetic Oil: This is a multi-viscosity motor oil suitable for various weather conditions. The “5w” represents its low-temperature viscosity, indicating it flows like a 5-weight oil when cold. The “30” represents its high-temperature viscosity, meaning it maintains a thickness equivalent to a 30-weight oil when the engine is operating at its regular temperature.
5w 20 Synthetic Oil: Similar to 5w 30, this synthetic oil has a lower low-temperature viscosity (flows like a 5-weight oil) but is slightly thinner at high temperatures (equivalent to a 20-weight oil). It’s often used in newer vehicles for improved fuel efficiency.
0w40 Synthetic Oil: This oil is designed for extreme cold-start conditions (flows like a 0-weight oil when cold) while maintaining a thicker viscosity at high temperatures (equivalent to a 40-weight oil). It’s commonly used in high-performance and European vehicles.
75w90 Synthetic Gear Oil: This is a synthetic gear oil used in manual transmissions and differentials. The “75w” indicates its low-temperature viscosity (flows like a 75-weight oil when cold), and “90” represents its high-temperature viscosity.
5w-20 Synthetic Oil: Similar to 5w 20, this oil flows like a 5-weight oil when cold but maintains a slightly thinner viscosity at high temperatures (equivalent to a 20-weight oil). It’s commonly used in modern engines for fuel efficiency.
0w 30 Synthetic Oil: This oil is designed for cold weather and flows like a 0-weight oil at low temperatures while maintaining a slightly thicker viscosity than 0w 20 at high temperatures.
10w30 Synthetic Oil: This oil has a moderate low-temperature viscosity (flows like a 10-weight oil when cold) and maintains that viscosity at high temperatures. It’s suitable for a wide range of vehicles and conditions.
0w16 Synthetic Oil: Designed for extremely cold conditions, this oil flows like a 0-weight oil when cold but has a thicker viscosity at high temperatures than 0w 20 or 0w 30.
15w 40 Synthetic Diesel Oil: This oil is designed specifically for diesel engines. It flows like a 15-weight oil when cold and maintains that viscosity at high temperatures.
15w50 Synthetic Oil: Suitable for high-performance engines, this oil flows like a 15-weight oil when cold but has a thicker viscosity at high temperatures (equivalent to a 50-weight oil).
80w90 Synthetic Gear Oil: This synthetic gear oil flows like an 80-weight oil when cold and maintains that viscosity at high temperatures. It’s commonly used in trucks and SUVs.
