Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.

Thereof What happens if I put 10W40 instead of 10W30? 10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures.

Does 10W30 hurt 5w30 engine? Synthetic oils will mix perfectly, as long as they have the same chemical composition. As a result, mixing 10w30 and 5w30 is not a problem since one will be topping up. It is not harmful to mix engine oils because 5w30 and 10w30 engine oils have close viscosity, so mixing them is not harmful.

Similarly, Does 10W40 hurt 10W30 engine?

Mixing 10W30 with 10W40

Some say that mixing them is fine as long as you don’t live in freezing weather. Even if you put together synthetic and conventional blends of these motor oils, they show no harm to your vehicle.

Can I use 5W40 instead of 5w30?

In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30Ā°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50Ā°C, as opposed to 30Ā°C.

Do I use 10W30 or 10W40? This is the reason your location is so important in selecting which oil to use. Between a 10W-30 and 10W-40, 10W30 motor oil would run smoother in colder climates while a 10W40 would be more effective in preventing engine wear and tear in warmer temperatures.

What is 10W-40 oil used for?

This oil weight is commonly used in diesel engines or in a smaller motorcycle engine too. The 10W-40 oil viscosity also often serves as an alternative for older engines with burning or oil leaking issues. Why is that? The 10W-40 engine oil has a thicker viscosity than, say, 10W-30 oil when the car engine is hot.

Can you use 15W40 instead of 10W40? A 10W40 oil will be thicker in the cold than 15W40 oil, but they will have the same viscosities at higher temperatures. The winter viscosity number dictates cold-start performance. A lower number indicates that the cold oil will be thinner, hence applying less static friction on the engine, and less drag.

Can you use 15w40 instead of 5w30?

Using 15w40 instead of 5w30 will increase your fuel consumption because of more load on your engine’s crank. No it won’t blow off,you will just wear your engine out quicker because the oil won’t flow to the moving parts as quickly !

When should I switch from 5w30 to 10w30? The oils only differ in cold weather viscosity. If you never see temperatures below zero F then either 5W30 or 10W30 is fine. If winter temperatures are regularly below 0 degrees F then 5W30 is what you should run and you can run it year round if the 30 weight is good according to your owner’s manual.

Is Thicker oil better for older engines? Older engines use more oil, but it gives them a better fuel economy. Older engines with more than 75,000 miles on them require a thicker oil that will lubricate their critical engine parts and prevent oil leaks, sludge, and deposits from forming.

Can I use 15W40 instead of 10W30? Always use the viscosity oil that’s recommended. Now sometimes they may indicate that if you live in a warm climate you can should use a 15w40 or if you are in a cold climate to go with a 10w30. The lower the numbers the thinner the oil.

Is 5w30 thicker than 5w40?

5w40 oil is not thicker has it has a higher viscosity. 5w30 has lower viscosity hence it is suitable to use in hot or lower temperatures. 5w40 has higher viscosity hence it is not suitable at all temperatures. 5w30 is a multi-graded oil which is suitable to use in lower temperature.

Can I use 15w40 instead of 5w30?

Your oil flow will get disturbed. 5w30 flows better than 15w40. 5w30 provides best cold start properties. Using 15w40 instead of 5w30 will increase your fuel consumption because of more load on your engine’s crank.

Which one is better 5w30 or 5w40? 5w30 can be used by different type of vehicles and in different range of temperatures, but is ideal for colder temperatures. 5w40 is often used in higher mileage engine sand performs better in warmer temperatures.

Can I mix 10W30 and 10W40? yes you can mix 10W30 with 10W40 as long as the engine will work with both 10W30 and 10W40. In certain high performance engines the 40 could be too thick in certain engines. Most of todays engines use much lighter oils to save on fuel economy and due to engine specifications.

Is 10W30 good for high mileage?

10W-30 motor oil makes for a decent high-mileage oil. It gives a better fuel economy while reducing the oil consumption for older engines. Older engines with more than 75,000 miles on them require a thicker oil that will properly lubricate their critical engine parts and prevent oil leaks, sludge, and deposits.

Can I use 10W40 instead of 10W30 in my lawn mower? Although SAE 30 motor oil is usually suggested for use in lawn mower engines, the safest option is to use the oil recommended by your lawn mower manufacturer. The same motor oil types used in cars, such as 10W-30 or 10W-40, can often be used in a lawn mower.

Which is heavier 10W30 or 10W40?

10W40 is ā€œthickerā€ than 10W30 when the car is at running temperature. Some people might also refer to it as ā€œheavierā€. Neither of these terms is technically accurate, but they do help to visualize it. In reality, we would say that 10W40 is more viscous than 10W30.

Is 10W30 thicker than 5w30? 10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil. Thicker oil offers better lubrication of motor and engine parts.

Which is better 10W40 or 15W50?

These viscosity index numbers are used to describe the relative thickness of oils for comparison. The 15W50 has numbers higher than the 10W40, therefore the 15W50 is thicker both at ambient winter test and engine operating temperatures. If your bike requires a 10w-40, then you should be looking at a ‘something’w-40.

Which is better 5W40 or 15W40? 5W is thinner than 15W when cold. Both will have a viscosity of a 40 grade. That cannot be said for both oils during the dead of winter. The 5W-40 will have a lower viscosity when the engine is started than the 15W-40; consequently the 5W-40 will start easier and lubricate quicker in the cold than the 15W-40.

When should I use 15W40 oil?

ADVANTAGE 15W-40 HEAVY DUTY DIESEL ENGINE OIL can be used with complete success in over-the-road diesel trucks, off-highway diesel equipment, farm tractors, and passenger cars and light trucks with diesel, turbo-charged diesel engines, or gasoline engines and is backward compatible with previous API Oil Categories.
