Question Can I use 10W20 instead of 5w30?

Because of its higher viscosity in lower temperatures, 10w30 is indeed thicker than 5w30. The motor oil will move slower than its competitor during the cold season. Higher or thicker viscosity metal oils have an improved seal in comparison to low viscosity oils. They offer better lubing of the engine and motor parts.

What is 10W20 oil used for?

MOTOR OIL EXTRA SAE 10W/20 is suitable for vehicles, motorbikes and stationary systems that are operated with monograde motor oils. EXTRA SAE 10W/20 monograde oils can also be used in specific gears and hydraulic systems for which monograde motor oils are required.

Is there 10W20 oil?

HD Fleet Oil SAE 10W20.

Is 5w30 thicker than 10W20?

The 5W-20 will remain a little thinner at operating temperature, as indicated by its lower “20” number, while 5W-30 will provide a slightly thicker lubricating film. When looking at 5W-30 vs 10W-30, they both provide the same viscosity at operating temperature, as indicated by their identical “30” ratings.

Is it OK to switch from 5w30 to 10w30?

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.

Should I use 5w30 or 10w30?

5W-30 multi grade oil is ideal for private vehicles and light-duty petrol and diesel engines. It also provides a better cold temperature start than 10W-30 oil. On the other hand, the slightly thicker oil,10W-30, provides better lubrication for commercial vehicles and heavy-load engine cars.

Can you put 10W20 in a 10w30 engine?

Bottom line, no you will not hurt the car by putting in either 10W20 or 10W30.

Can I mix 10w30 and 10W20?

You will be fine, just don’t overfill. In the middle of the marks is just great too. Best to change as soon as you can.

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 10w30 in diesel engine?

Can I Put 10w-30 In A Diesel Engine? Yes. There is no problem with using the 10w30. There is no difference in weight between the three 0w, 5w, and 10w30 oils.

Can we use 20w40 instead of 10w30?

20w 40 is a thicker oil when compared to the original 10w 30 oil. So 10w 30 oil is going to flow better than 20w40 oil when you initially start it and also run it. If the oil flows better the better the oil will lubricate and protect engine parts.

Which is better 10w30 or 20w40?

20w40 is thicker at high temperatures than 10w30 It is desirable for lubrication at operating temperatures to be high. 20w40 is better than 10w30 at normal operating conditions.

Can I mix 5w30 and 10w30?

Adding 10W30 to your current mix is safe, and will not cause your engine to run any worse. But keep in mind that 10W30 has more density than 5W30. These two motor oils are very similar in viscosity
hence, they might mix perfectly in your engine. Therefore, you can mix 5W30 with 10W30 with no ill effects whatsoever.

Can I substitute 10w30 for 5w20?

Moreover, many of us know that thinner oil is easy to ignite even at the temperature below negatives. Therefore, if the temperature is below zeros, use 5w20 oil. In the same case, 10w30 oil can take hours to ignite in winters. So, it’s better to choose oil type wisely depending on the weather.

What oil is thicker than 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.

Should I use 10w30 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.

When should I use 10w30 oil?

This engine oil will maintain its viscosity even under high temperatures. It is suitable for engines using advanced fuels such as biofuel and biodiesel. Through 10w30 can be used in cold weather, but it is more suited for hot weather use.

Can I put 10w40 instead of 5w30?

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.

What happens if I use 5w30 oil instead of 10w30?

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.

Can you put 10W40 in a 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. However, this is true only if you mix in a quart of the other type to your usual engine oil.

Is 5w30 and 10w30 the same?

Both the oils have similar viscosity at 100 degrees Celsius but 5w30 grade oil will thicken less than 10w30 grade oil in cold climate. This means 5w30 grade oil will flow effectively in low temperatures, whereas 10w30 oil will flow effectively in high temperatures because of the smaller temperature window.

Which oil is thicker 10w30 or 5w20?

Main Differences Between 5w20 and 10w30

5w20 is thinner at lower temperatures, whereas 10w30 is thicker at lower temperatures. 5w20 is better for cold-weather starting, whereas 10w30 is better for sealing action. Light duty petrol and diesel engines use 5w20, whereas large weight carrying engines need 10w30.

What will happen if I put 5w30 instead of 5w20?

What Will Happen If You Put 5w30 Instead Of 5w20? Using 5W-30 instead of 5W-20, you risk damaging your car’s engine because the internal engine components work with 5W-20 motor oil. 5W-20 and 5W-30 motor oil both have the same winter rating. It means that both motor oils have the same viscosity under cold temperature.

What oil is recommended for high mileage vehicles?

High mileage oil is designed for vehicles with more than 75,000 miles. Such oil features additives that help protect seals. This leads to less leakage and oil burn-off, which can be common in older cars. If your vehicle is high-mileage and high performance, it’s suggested that you go with this type of synthetic oil.

Will heavier oil hurt my engine?

This is not a good idea, as it will harm your health. The use of a heavier grade than recommended can result in a decrease in fuel economy, higher engine loads, and eventually shortened engine life. The use of a lighter grade than recommended can result in excessive mechanical wear and reduced engine life as well.

Will synthetic oil hurt older engines?

Myth: Full synthetic oil is not good for high mileage cars or older vehicles. The myth is rooted in the idea that synthetic oil is “slipperier”—lower in viscosity, or not as compatible with seals and will therefore leak or leak more in places conventional oil might not. Again, completely untrue.
