What does 5 and 40 mean in engine oil?
The 5 means that the oil will flow at zero celsius the same way a 5-weight oil would. The 20 and 40 mean that the oil will flow like a 20 and 40-weight respectively at engine operating temperature (180-195C usually). The actual viscosity of the oil is therefore the SECOND number. The first number just indicates how resistant it is to cold.
What is the viscosity of 5W20 oil?
The 5w20 has a viscosity grade of 5 during winter or cold temperatures. However, its viscosity reaches 20 in hot temperatures. 5w20 oil performance is excellent in winters and flows through the engine smoothly to enhance overall performance.
Is it OK to use 10w30 instead of 5W-30?
You can use 10w30 instead of 5w30 oil since both meet the SAE standard for viscosity at operating temperatures. Generally, the viscosity difference between the two is neglectable. However, it’s important to note that a 10w30 oil will move slower than a 5w30 oil in cold environments.
Is 5W-30 oil better than 10W-30?
The lower the oil’s “W” viscosity, the more readily it will flow when cold. In this case, 5W-30 will flow more easily at startup than 10W-30. In fact, some automakers allow you to switch to a lower viscosity oil depending on weather. Find the Right Viscosity Oil for Your Engine
Should I use 20w50 oil on my engine?
It’s important to note, that your engine’s oil pump, and thus the engine, has to work extremely hard to pump thicker oil and maintain oil pressure, so folks that would resort to 20w50 oil on their tired, old engine would also sacrifice horsepower using it.
Should I use 10W – 30 oil if it is cold?
However, the 10W – 30 oil will be thicker when it is cold. As per API recommendations (1) for car engines, you can use 10W – 30 oil if the maximum expected outside temperature is above -18°C (0°F). If you are living in an area where the outside temperature can go below zero; It is better to use 5W – 30.
What Acea rating should 10W30 engine oil have?

Can I mix 30 and 40 oil?
Typically, it is not a good idea to mix oils, though you may be able to get away with it if the grades are fairly similar (such as using a 30 grade when a 40 grade is recommended). You should never mix conventional oil with synthetic oil.
Can you mix 5W30 and 5w40 engine oil?
We can never be certain of how stable the mixture of two oil weights will be. But for your peace of mind, if you are already low on engine oil, a mixture of 5w30 with 5w40 can still do the job. It can still provide proper viscosity and lubrication to the internal parts of your engine even if it’s not ideal.
What is the difference between -40 and -30?
The -40 and -30 are numbers which describe the high temperature viscosity of the oil, with 40 remaining “thicker” at higher temperatures than the 30. You may have been. There are different properties of both. However, faced with running low on oil, it would be better to add non-synthetic oil, than to be running low on synthetic oil.
What is the difference between 40W and 30W oil?
But, lighter, more flowing oils cause less dry-running in the engine, and therefore less wear and tear. In high-mileage engines, 40W oils create a lower oil consumption than 30W oils, which is less wearing on the engine, requires less frequent oil changes and top-ups and is less expensive in the longterm.
Can you mix two engine oils?
The simple answer is YES; you can mix the two oils; not just because they have the same weight, but because it is safe to mix two different engine oils. However, we do not encourage the mixing of motor oils. Why? Because the act does not guarantee any advantage over using one type of oil.
