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.
Is 10w40 good for high mileage?
Mobil 1 High Mileage 10W-40 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils†), including: Cars.
Is 10W-40 better than 5w30?
The first number in the motor oil’s name describes the oil’s cold viscosity. … 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.
What is 10W-40 motor oil good 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.Is 10W40 good for summer?
Similarly, SAE 10W-40 motor oil performs well in cold weather conditions. It has the same low-temperature limits as the 10W-30 but is better in higher temperatures. … Either 10W30 or 10W40 for summer use is fine; however, 10W-40 motor oil will better protect your engine.
What happens if you 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.
What is 10W-40 engine oil?
The designation “10W-40” indicates a multigrade oil that is toward the low end of the SAE scale in cold weather, but at the upper end in hot conditions. 10W-40 oil is therefore good for a wide range of weather conditions.
Can you put 10W30 in a 10W40 engine?
So if you change your oil from 10W30 to 10W40 you should take care about the weather in your surroundings. Changing from 10W30 to 10W40 will not do any effect on your engine if you choose right one for the right season. Its totally safe you can go for it.Is 10W40 a synthetic oil?
Semi-synthetic oils such as 10W40 have long been the standard. Their base is refined crude oil, which is then blended with additives.
Can I go from 10W40 to 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.
Article first time published onCan you put 10W40 in a 5W40 engine?
No, you can use 5w-40 anywhere a 10w-40 is recommended. At operating temperatures, both oils are 40wt and are equivalent. What matters most is the operating temp viscosity (the 2nd number). The first number (with a “w”) only applies to colder oil viscosity.
Which is better 5W40 or 10W40?
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 10W40 or 10W50?
The 10W40 has a viscosity index of 160, and the 10W50 has a viscosity index of 167 – meaning, the 10W50 has less variation in viscosity over the temperature range. The 10W40 has a higher flash point of 250ºC than the 10W50 (232ºC) – so it will withstand higher temperature than the 10W50.
What is 10W 50 oil used for?
10W50 oil is a high-performance engine oil that offers outstanding engine reliability and temperature stability under extreme driving conditions. It’s used for a wide range of motorsports and modern engines with turbochargers.
What is the thickest engine oil?
60 is the thickest oil in general use, but there are racing grades that go to 70. Most lubricating oils are now multigrade. There are now some additions to the table for very low viscosity, and these go in increments of 4 (4, 8, 12, 16) to distinguish from the 5 increment Winter grades.
Is 10w40 good for petrol engine?
A very high performance semi-synthetic oil, specially developed for petrol & diesel engines.
Will thicker oil damage my engine?
Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.
What engine oil should I use for a high mileage car?
Some mechanics recommend switching to a thicker (higher viscosity) oil — such as 10W-30 full synthetic oil instead of 5W-20 full synthetic — or using oil additives to stop leaks.
Is 10W oil better than 5W?
A 10W or 5W is the index for how easily the oil flows in winter (hence the W). A 10W oil thickens more than a 5W. The other number indicates the oil’s resistance to thinning at high temperatures.
Can I put 5W 40 oil in my car?
To answer your question: No, going to a 5w-40 version of an approved oil for your engine isn’t going to hurt your engine under normal driving conditions. Your 5w-30 oil might break down more quickly if you regularly drive in temps above 35C.
Which is better 10W40 or 15w50?
At low temperature the 10W oil will flow better than a 15W oil. So the 15W-50 oil is “thicker” at cold temperatures than the 10W-40, therefore it will flow worse on start up; but being a little “thicker” it and maintains its viscosity at high temperatures better than the 10W-40.
Can I use 20w40 instead of 10W40?
10w-40 it’s mean viscosity 10 when weather cold and viscosity 40 when hot. Similarly, viscosity 20 when cold and viscosity 40 when hot. 10w-40 can give better performance in replace of 20w -40 oil.
Can you mix 10W-40 and 10W 50?
There is absolutely no harm in mixing different grades of engine oil! All motor oils are required to comply with international standards which include a compatibility test. This means that any branded engine oil will mix with the standard test oil in any proportions and the mixture will still perform as specified.
What cars use 10W60 oil?
- Popular for newer BMW M-cars applications like E46, M3 and E60 M5.
- Recommended for API SN/SM/SL/SJ/SH/SG/CF and ACEA A3/B3/B4.
When should I use 20w50 oil?
What Is 20W-50 Oil Used For? 20W-50 is a common motor oil used in moderate-to-large diesel and gasoline engines, high-performance motorcycle bikes, and aviation vehicles. Its resistance to thinning at high heat also makes it popular as a racing oil and high temperature driving.
Is 10w30 thicker than 10w50?
10w30 is thinner than 10w50, the grade of oil represents the viscosity of oil, if the grade of oil is high then the viscosity is high, hence 10w50 is thicker then 10w30.
