Difference Between 5w30 and 10w40

If you’re like most people, you know that oil is important. But do you know exactly what type of oil is best for your vehicle? And if so, do you also know the difference between 5w30 and 10w40? If not, we’re here to help! Just keep reading for all the details on these two types of oil and how they differ from each other.

What is the difference between 5w30 and 10w40?

The 5w30 and 10w40 are two different types of oil grades. The number “5” in 5w30 stands for its weight, while the number “10” in 10w40 stands for its viscosity. So what’s that? In short, it indicates how thick or thin your motor oil will be at a certain temperature range (in this case 70 degrees Fahrenheit).

The lower the numerical value of an engine oil grade (like 5w30), the lighter it is on your engine parts–and therefore faster to burn off during combustion cycles. But because these lighter weight oils evaporate more quickly from hot surfaces like pistons and cylinders, they may not protect them as well as heavier-viscosity alternatives such as 10W40 or 15W50 synthetic blends do over time–resulting in increased wear rates due to friction between moving parts inside your engine.*

5W30 vs 10W30

5W30 and 10W30 are both viscosities (a measure of how easily a liquid will flow) of motor oil. The W stands for winter, so these oils tend to be used in colder climates where you’ll see lower temperatures and more frequent starts and stops.

The difference between 5W30 vs 10W30 isn’t just about what type of engine you have; it’s also about how well each performs under different conditions. 5W30 is thinner than 10W30, which means it flows better at low temperatures but not as well when things get hot. Conversely, 10W30 has greater viscosity than 5W30 so it flows better at high temperatures but not as easily when they’re cold out.

5W30 vs 10W40

• 5W30 is a lighter weight oil.
• 10W40 is a heavier weight oil.
• 5W30 is better for cold weather because it flows easier when cold, and provides more protection from heat breakdown at high temperatures than 10W40 does (which means that you don’t need to change your oil as often).
• 10W40 is better for warm weather because it doesn’t get so viscous with age, allowing for better lubrication in hot climates where viscosity tends to increase over time.

The two common oil grades are 5w30 and 10w40.

The two common oil grades are 5w30 and 10w40. The “W” stands for winter, which means that the lower number (5) indicates how thin the oil is. The higher number (10) indicates how thick it is.

The thinner an oil, the better it can flow through your engine’s tight spaces at low temperatures–which means you’ll get better protection against cold starts or when your car hasn’t been driven in awhile. This makes 5w30 great for colder climates where you expect to start up your car regularly during winter months but rarely use it during summer months because there’s not much need to drive around when temperatures are hot outside!

On the flip side of things, if you live somewhere hot all year long then using a thicker grade like 10w40 may be more beneficial to keep things running smoothly throughout every season without sacrificing performance under normal conditions; this type of motor oil will provide more lubrication over time than its thinner counterpart because its molecules do not break down as easily under high heat conditions found within internal combustion engines (ICEs).

The main difference between 5w30 and 10w40 is the viscosity. 5W30 has a higher viscosity than 10W40, which means it has less flow rate or resistance to flow.
