Can you put 15W40 in a 10w30 engine?

This is why many heavy-duty oils are moving from the traditional 15W-40 to 10W-30. If the engine is designed and manufactured to use a 10W-30, it can improve fuel economy and power over using a 15W-40. … And the slower it is sheared, or the thinner the oil is, the less energy we lose.

Can I use 10W 40 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.
