1. Conventional Oil: Conventional oils, made from refined crude oil without additional additives, typically have higher freezing points compared to synthetic or synthetic blend oils. The pour point of conventional oils can range from -10 to -22 degrees Fahrenheit (-23 to -30 degrees Celsius).
2. Synthetic Oil: Synthetic oils are chemically engineered lubricants made from synthetic base fluids and advanced additives. They have lower freezing temperatures and better flow properties even in extreme conditions. Synthetic oils can have pour points as low as -40 to -58 degrees Fahrenheit (-40 to -50 degrees Celsius).
3. Synthetic Blend Oil: Synthetic blend oils are a combination of synthetic and conventional base oils. They offer improved performance compared to conventional oils but may not reach the same low freezing temperatures as full synthetic oils. Synthetic blend oils can typically have pour points between -20 to -30 degrees Fahrenheit (-29 to -34 degrees Celsius).
4. Multi-Grade Oils: Most modern car oils are multi-grade oils, which means they have a wider temperature range and can flow more effectively at both low and high temperatures. They are denoted by a double-number viscosity grade, such as 5W-30 or 10W-40. The first number (before the "W") indicates the oil's viscosity at low temperatures, while the second number indicates its viscosity at high temperatures. A lower first number (lower "W" rating) indicates a lower freezing temperature and better low-temperature flow properties.
It is important to refer to the owner's manual of your specific vehicle to determine the recommended oil viscosity grade for your car. Using oil with a suitable freezing temperature for the climate and weather conditions in your region is crucial for ensuring proper lubrication and protecting your engine.
