Difference Between 5w30 and 0w40

When shopping for motor oil, you may come across two different viscosity grades: 5W30 and 0W40. While the difference between these numbers may seem like a simple misunderstanding, there is actually more to it than what meets the eye. In this article, we will provide a brief overview of each type of oil along with some additional details that can be helpful when deciding which one to use in your vehicle or equipment.

5w30 is low viscosity 5w30 is a medium to a high grade motor oil. It has a typical pour point of -38 degrees celsius and a flash point of 220 degrees celsius.

5w30 is a low viscosity oil. It’s a medium to high grade motor oil, meaning it has good wear protection and good oxidation resistance. 5w30 has a typical pour point of -38 degrees celsius and a flash point of 220 degrees celsius.

0w40 is an ultra-low viscosity oil that is designed for use in vehicles with turbocharged diesel engines. It typically has a pour point of -25 degrees celsius and a flash point of >270 degrees celsius.

0w40 oil is an ultra-low viscosity oil that is designed for use in vehicles with turbocharged diesel engines. It typically has a pour point of -25 degrees celsius and a flash point of >270 degrees celsius.

0w40 oils are very thin, so they flow easily when cold and won’t gum up your engine or cause excessive wear during startup. They’re also more stable than other types of engine oils, which means they resist breakdown from heat better than other types of motor oils (like 5W30).

The main difference between 5W30 and 0W40 oils is their viscosity rating. That said, there are also some other differences between these two products that should be understood before deciding which one to use in your vehicle or equipment.

• Viscosity: The term “viscosity” refers to how thick an oil is at room temperature (and under other conditions). The higher the number on this scale, the thinner an oil will feel when poured from its container into your hand. So if you’re using an engine with high-performance driving requirements–such as racing cars or motorcycles–your best bet is going to be an SAE 30 grade motor oil for its high level of performance at low temperatures.* Temperature range: On top of being able to measure viscosity through numbers such as 10W30 or 15W50 (which indicate they have been tested up until certain temperatures), there’s also another way we classify our engine lubricants based on how well they perform within certain ranges of heat levels.*

Viscosity refers to the flow characteristics of a lubricant, meaning how easily it moves through an engine or transmission system under pressure at various temperatures. The higher the viscosity rating on an oil, the thicker it becomes at lower temperatures so that it takes longer to move through your engine.

The higher the viscosity rating on an oil, the thicker it becomes at lower temperatures so that it takes longer to move through your engine.

Viscosity is measured in centistokes (cSt). A higher cSt number means that your oil has better cold weather protection than one with a lower cSt number because it will remain thick enough to provide adequate lubrication when temperatures drop below freezing point.

Lower numbers indicate thinner oils that allow more flow at lower temperatures; however, they can cause wear issues because they don’t contain enough additives or they may not meet specifications for certain applications like hot weather driving conditions where the temperature gauge can approach 120+ degrees Fahrenheit (49 degrees Celsius).

In general, 5W30 is a medium to high grade motor oil. It has a typical pour point of -38 degrees celsius and a flash point of 220 degrees celsius.

The lower numbers indicate thinner oils that allow more flow at lower temperatures; however, they can cause wear issues because they don’t contain enough additives or they may not meet specifications for certain applications like hot weather driving conditions where the temperature gauge can approach 120+ degrees Fahrenheit (49 degrees Celsius).

The best way to decide which viscosity is right for your vehicle is by consulting with a professional.
