Yes you can use a 5w-40 motor oil in your car. But motor oils with that wide a temperature range are subject to what is called “shear”. That is the oil will break down and lose it’s viscosity faster than the oil recommended for your car.
Can I use 5w40 oil instead of 5W30?
If you find yourself asking whether can I use 5w40 oil instead of 5w30, the answer is yes, in most cases. 5w40 oil is thicker than 5w30 oil, and provides better protection for your engine, particularly during cold starts.
Does my Kia use 5W-30 oil?
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 is the best engine oil?
Royal Purple HMX High Mileage Synthetic Oil This is another full synthetic oil that provides superior wear protection for your engine.

Should I use thicker or thinner engine oil?
Bottom line on using thicker oil or thinner oil Using a viscosity one grade higher or lower than what’s recommended for your engine likely won’t do lasting harm. But, to alleviate any concerns about engine protection and your vehicle warranty, it’s best to use the viscosity recommended in your owner’s manual.
Is 5W-30 oil OK for car?
5w30 oil is one of the most commonly used motor oils because it is suitable for a wide variety of vehicles and engine types. 5w30’s viscosity range means it can lubricate, seal, and protect an engine’s internal components in a range of climate conditions.
Is 5W-30 oil good for car engine?
5W-30 oil is unsuitable for extremely high temperature use since, at these temperatures, car engines require a thicker oil with proper bearing support and cushioning. As 5W-30 oil is comparatively thinner than any other multigrade oil like 5W-40, it may not lubricate the engine well. 2. Is 5W-30 Oil Suited For Heavy-Duty Use?
What is the difference between 5W-20 and 5W-30?
The main difference is 5W-20 is thinner than 5W-30 at high temperatures. 5W-20 and 5W-30 are similar enough oils they can be mixed and interchanged. Although in this case mixing or substituting these oils it is critical to understand why and understand things like what the numbers of the oil ratings mean.

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.
Can I use 5W 40 instead of 5W 20?
The quick answer is no you should not use 5w20 when 5w40 is recommended by manufacturer. The thinner oil may not lubricate the internal engine as designed.
What is the difference between Mobil 1 5W-20 and 5W-40?
While Mobil 1 5W-20 has corresponding viscosities of 49.8 and 8.9. Clearly the 5W-40 is a MUCH thicker, denser, heavier oil (both full synthetics). Use the recommended viscosity for your particular application. You should only adjust those figures within the general approved range.
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.
