Is 10w40 better than 5W-30?

5w30 oil is especially well suited to vehicles operating in cold climates. 5W-30 motor oil is mainly of cold-weather viscosity quality….Comparison Table Between 5w30 and 10w40.

Can 10w40 be used 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.

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

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.

Which oil is better 10w30 or 10w40?

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.

Can you put 10w40 in a 10w30 engine?
