Selecting the correct oil viscosity is one of the most critical decisions for maintaining the longevity and performance of any engine. You will see ratings such as 5W-30 or 10W-40, where the "W" stands for winter.
Synthetic vs Conventional Oil Viscosity: Performance Differences
Consequently, many manufacturers now require specific performance certifications alongside the viscosity rating, such as API SP or ILSAC GF-6. Always verify that the oil bottle matches the exact specifications listed in the owner’s manual, not just the viscosity number.
Conventional Lubricants The type of base oil used significantly impacts performance across temperature ranges. The number following the dash represents the oil's viscosity at the engine's normal operating temperature of 100°C, with higher numbers indicating a thicker, more resistant oil film.
Synthetic vs Conventional Oil Viscosity Explained
The number preceding the "W" indicates the oil's cold-flow properties; a lower number means the oil remains thinner in cold temperatures, allowing for better circulation during a cold start. This is why adhering to the Original Equipment Manufacturer (OEM) recommendation is the safest strategy for standard driving conditions.
