Does it matter if 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.

What happens when you mix 5W 30 and 10W40?

From Shell.ca: “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.

Can I use 10W-40 in my truck?

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. Trucks.

What’s the difference between 10W 30 and 10W-40 oil?

The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature. Remember that using oil with a viscosity that is too high can result in excessive oil temperature and increased drag.

Can you use 10W 30 instead of 5w-30?

Can I Mix 10w30 and 5w30? Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine.

What is the difference between 10W-40 and 5w-30?

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.

Can you mix 10W-40 and 10W-30?

Most mechanics and vehicle owners avoid mixing 10W-30 with 10W-40 oil for several reasons. One is to prevent a decrease in oil pressure when cornering at high revs, resulting in spinning a bearing or two. Bear in mind that mixing motor oils may affect your vehicle’s warranty and fuel consumption.

What’s the difference between 5W 40 and 10W-40?

The main difference between the two oil types is that one is thinner than the other. The 5W40 is thinner than the 10W40 at lower temperatures. If your motorcycle requires a 10W40 engine oil, there is no need to go for 5W40 oil. The 10W40 will just work well with your motorbike.
