The "15w" signifies its low-temperature viscosity, where the "W" stands for winter, and the number indicates how readily the oil flows when the thermometer drops. By keeping the internal components cleaner and reducing the likelihood of deposits, the oil actively promotes a longer engine lifespan, preserving the value of the investment for years to come.
When the mercury rises, the high-viscosity index ensures the oil does not become overly thin, maintaining a stable lubricating barrier between moving parts. This dual-temperature protection is particularly valuable for vehicles that operate in regions experiencing harsh winters and hot summers without the need for seasonal oil swaps.
