Car manufacturers usually specify 5W-20 or 5W-30 oil, though some require 10W-30.
These three ratings cover just about every light-duty vehicle on the road, though this is changing as engines become more precise and fussy about specific types oil.

Can you use 5w30 oil instead of 5w40?
If you are racking your brain to choose between 5w30 and 5w40, we recommend you go with 5w30. However, if it is too expensive or not available for use, you can always go with the 5w40, which is just as good and will not cause any damage to the engine parts.
Can I use 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.
Can I put any oil in my car?
You should use synthetic oil if you car manual instructs you to do so but otherwise, it won’t matter too much. Any oil used should be multi-grade, however. But it is worth noting that synthetic oil is generally considered to perform better than its conventional alternative.
Which oil is better 5w30 or 10w30?
When to Use 10w30 vs 5w30
The only difference between these two oils is cold flow ability: a 10w30 oil will move slower than a 5w30 oil during cold startups. At operating temperatures, both oils will have the same viscosity (30) and will flow and protect identically.
Which brand engine oil is best?
5 Best Motor Oil Products of 2019

Should I use 5w30 or 5w40?
In fact, the only major difference between 5w30 and 5w40 is the viscosity in warmer temperatures. This makes the 5w30 better suited for colder temperatures and the 5w40 better suited for warmer ones.
Is 0w40 better than 5w40?
Well, for a start, we can see that they have the same viscosity when heated to normal engine operating temperatures so that won’t set them apart. If you live in a part of the country that sees very cold winters then 0W40 is likely a better choice for your engine than 5W40.
What 5w 40 oil means?
The two numbers in the 5W-40 indicate the weight or viscosity of the engine oil as tested by SAE. Viscosity is defined as a fluid’s resistance to flow: The higher the number, the higher the fluid’s resistance to flow, or the thicker the fluid. The “W” indicates that the first number is the “cold” or “winter” rating.
What happens if you put 5w30 instead of 10w40?
The ‘w’ means winter, implying the viscosity at which the oil will flow when the car is starting or at low temperatures. The 5w30 oil will flow better at low temperatures than the 10w40 oil. At high temperatures, the 5w30 oil is thinner than that of 10w40 since 30 is lower than 40.
What happens if you mix 10w40 with 5w30?
“If you mix viscosity grades such as a 5W30 low-viscosity oil and a 10W40 higher-viscosity oil, it is reasonable to expect that the resulting product will have viscosity characteristics which are thicker than the 5W30, but thinner than the 10W40.
Will thicker oil damage my engine?
Higher parts temperatures, more wear. Too thick or too thin oils can both be bad for engines, but damage is neither immediate nor catastrophic; it just reduces overall engine life. Always use the oil recommended by the engine manufacturer.
