Can I use 10W-40 instead of 5W-30?

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.

Can 10W-40 be used instead of 10W 30?

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.

What happens if you put 10W-40 instead of 5W 40?

10w40 is thicker than 5w40, ONLY when cold. At operating temperature it is exactly the same. Multi-viscosity oils with a lower W number are specifically designed to flow better, and thus lubricate better, at very low temperatures. There is no need to use a 5w-40 if the vehicle only requires 10w-40.

What is the difference between 10W-40 and 5w 40 engine oil?

The main difference between the two oil types is that one is thinner than the other. The 5W40 is thinner than the 10W40 at lower temperatures. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity).

What is 5w 40 oil used for?

5w40 is a motor oil that helps the engine to work smoothly and the moving parts from overheat because of friction. 5w40 transfer heat from the combustion cycle and assist to keep the engine clean by burning by-product and protects the engine from oxidation.

What is the difference between engine oil 5W 30 and 5W 40?

5w30 is engine oil that has lower viscosity 5 and higher viscosity 30. 5w40 is engine oil that indicates the weight and viscosity of the engine. 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.

What is the difference between 10W-40 and 10W-30?

The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature. Remember that using oil with a viscosity that is too high can result in excessive oil temperature and increased drag.

Should I use 5W-40 or 10W-40?

The main difference between the two oil types is that one is thinner than the other. The 5W40 is thinner than the 10W40 at lower temperatures. If your motorcycle requires a 10W40 engine oil, there is no need to go for 5W40 oil. The 10W40 will just work well with your motorbike.

When should I use 5W-40?

5w40 is better for starting your engine at low temperatures as it flows more easily at these temperatures. When the engine is running and hot, 5w40 and 10w40 have high viscosities and are equally effective in protecting against engine wear.

Which is better 5W 30 or 5W-40?

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

Which is better 5W 30 or 5W-40 oil?

In general, 5w30 is a great multi-grade oil for different temperature specters. It is also more fuel efficient. 5W40 is a motor oil that penetrates to the active mechanisms faster, and provides excellent lubrication on start up.

When should I use 5W 40?

5w40 is better for starting your engine at low temperatures as it flows more easily at these temperatures. When the engine is running and hot, 5w40 and 10w40 have high viscosities and are equally effective in protecting against engine wear.

What is 5W 40 oil used for?

5w40 is a motor oil that helps the engine to work smoothly and the moving parts from overheat because of friction. 5w40 transfer heat from the combustion cycle and assist to keep the engine clean by burning by-product and protects the engine from oxidation.

Which oil is better 5W 30 or 10W-30?

5w30 provides better lubrication compared to 10w30. It is best suited for private vehicles and light-duty diesel and petrol engines, while 10w30 is more suitable for commercial vehicles and other cars with heavy load engines.

When should I use 5w 40?

5w40 is better for starting your engine at low temperatures as it flows more easily in this environment. When the engine is running and hot, the differences are negligible, 5w40 and 10w40 both have high viscosities and are equally effective in protecting against engine wear.

What happens if I use 5w-30 instead of 5w 40?

There’s not going to be much functional difference between a 5w-30 and 5w-40 as there’s a lot of functional overlap in the recommendations. The lower weight might yield better efficiency under light load operating conditions, but higher weight might yield better protection under higher load operating conditions.

Is 10W 30 thicker than 5W 40?

In the main, 10W-40 has higher viscosity than 5W-30 across the entire temperature range. It’s thicker, heavier.

Is 5W-40 oil good for hot weather?

5w40 is better for starting your engine at low temperatures as it flows more easily at these temperatures. When the engine is running and hot, 5w40 and 10w40 have high viscosities and are equally effective in protecting against engine wear.

Is 5w40 good for summer?

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.

What is the difference between 10W 40 and 5W-40?

The main difference between the two oil types is that one is thinner than the other. The 5W40 is thinner than the 10W40 at lower temperatures. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity).

Is 10W-40 thicker than 5w-30?

A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.

Which is better 5W-30 or 5W-40?

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

The 5W40 is thinner than the 10W40 at lower temperatures. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity). However, the main difference between these two engine types is that the 5W40 can work better than 10W40 in very cold places.

Which is better 5W or 10W?

A 10W oil thickens more than a 5W. The other number indicates the oil’s resistance to thinning at high temperatures. Amsoil claims that it withstands the stress and high-running temperatures while lubricating the performance parts to avoid sludge buildup.

What is 10W 40 oil used for?

The 10W-40 engine oil has a thicker viscosity than, say, 10W-30 oil when the car engine is hot. This helps it lubricate older moving parts in high mileage engines while being less likely to leak.
