The first number, followed by the letter “W,” denotes the oil’s viscosity in cold weather, while the second number reflects its viscosity in hot conditions.
The “W” in a viscosity rating stands for “winter,” indicating the oil’s flowability at low temperatures. Lower W numbers denote thinner oils that flow more easily in cold weather. Meanwhile, the second number measures the oil’s viscosity at 100°C, representing its thickness and ability to maintain lubrication at operating temperatures. Understanding viscosity ratings is crucial when choosing the right motor oil for your vehicle, as it ensures proper lubrication across various temperatures, enhancing engine protection and performance.
The Difference Between 5W-30 And Sae 30
The main difference between 5W-30 and SAE 30 is their viscosity. The “W” in 5W-30 stands for winter, indicating its cold-weather performance. The number before the “W” (5) represents the oil’s flowability in cold temperatures. On the other hand, SAE 30 does not have a “W” as it is a monograde oil, meaning it does not have the same cold-weather flowability as 5W-30.
5W-30 is a multigrade oil, designed to perform well in both high and low temperatures. In contrast, SAE 30 is a single-grade oil, recommended for use in warmer temperatures. Therefore, the choice between 5W-30 and SAE 30 largely depends on the climate and the specific requirements of the vehicle. While 5W-30 may offer better cold-weather protection and start-up lubrication, SAE 30 may be more suitable for engines operating under consistently warm conditions.
Understanding the differences between these two types of motor oil can help car owners make informed decisions about which oil is best suited for their vehicles based on their driving conditions and manufacturer recommendations.

On the other hand, SAE 30 oil is a single-grade oil predominantly designed for use in warmer climates or steady operating conditions.
Choosing the right motor oil for your vehicle can directly influence engine performance, fuel efficiency, and overall longevity. While modern engines are designed to work with a range of oil viscosities, using the recommended grade can optimize engine performance and fuel economy. It is crucial to refer to the manufacturer’s specifications and follow their recommendations for the motor oil viscosity that is best suited for your vehicle. In doing so, you can ensure that your engine operates smoothly and efficiently, without any unnecessary wear or strain.
The Impact On Fuel Economy
When it comes to the impact on fuel economy, the choice between 5W30 and SAE 30 motor oil can have significant implications. 5W30 motor oil is designed to flow more easily at lower temperatures, reducing engine friction during cold starts and leading to improved fuel efficiency. This can result in better gas mileage, especially in regions with colder climates where the engine needs to start in suboptimal conditions.
On the other hand, SAE 30 oil may not provide the same level of efficiency in cold weather, which can lead to increased fuel consumption during start-up and shorter trips.

It’s important to consider the climate and driving conditions in which the vehicle operates when determining the most fuel-efficient motor oil for optimal engine performance and longevity.
Temperature Considerations
When considering motor oil, temperature plays a crucial role in its performance. The “5W” in 5W30 denotes the low-temperature viscosity of the oil, with the “W” signifying “winter.” This means that the oil has been tested and proven to perform well in cold conditions. On the other hand, SAE 30 has a single viscosity rating, meaning it does not have the same ability to flow easily in cold temperatures.
For vehicles operating in varying climates, 5W30 offers a significant advantage due to its ability to provide proper lubrication even when the temperature drops. It maintains its flow at low temperatures and continues to protect the engine components. Furthermore, the multi-grade nature of 5W30 makes it suitable for driving in both cold and hot environments, ensuring that the engine is adequately lubricated regardless of the temperature.
