Conventional Oils Once you understand viscosity, you must decide between synthetic and conventional oil. Similarly, if you live in a region with harsh winters, a 0W or 5W oil is essential to ensure the engine turns over easily.
The "W" stands for winter, and the number before it indicates how the oil behaves in cold temperatures. Viscosity Grade Best For Typical Performance 5W-20 New economy cars Excellent fuel economy, cold protection 5W-30 Most modern vehicles Balanced protection and efficiency 10W-40 Older engines or warm climates High temperature stability Driving Habits and Climate Considerations Your driving environment and style play a significant role in the question of what oil to use.
