Winter is upon us, and we are talking about Viscosity Index and Cold weather protection. So lets get into it!
When it's cold outside, the viscosity index (VI) of oils becomes important for your car's engine. Oils with a higher VI are needed to ensure smooth start-ups, reduce wear when you first turn on the engine, and provide enough lubrication even in freezing temperatures. These oils can keep their thickness, which means they protect your engine better and don't become too thin in the cold. By using oils with a higher VI, your car's engine can start easily and work well, decreasing friction and wear during those crucial moments when you start your car in the cold.
