What happens if you use 5W40 instead of 5W20?

5W20 offers better fuel economy than 5W40 and some engines are optimised for using it and lubricating some parts. If you drive short distances only and engine remains cold, then using W40 instead W20 is not an optimal choice.

What kind of oil does a 2007 Ford Explorer take?

For the 4.0 L V6 it is recommended to use 5W-30 Synthetic Motor Oil and 5W-20 Synthetic for the 4.6 L V8 engine. The capacity for the Explorer iS5 quarts with a filter for the 4.0 L V6 and 6.3 quarts with a filter for the 4.6 L V8 engine. Oil is important because it will help keep the engine clean and running longer.

Can I use 5W40 instead of 10W40?

The 5W40 is thinner than the 10W40 at lower temperatures. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity). However, the main difference between these two engine types is that the 5W40 can work better than 10W40 in very cold places.

Which is thicker 5w40 or 10W40?

10w40 is thicker than 5w40, ONLY when cold. At operating temperature it is exactly the same. Multi-viscosity oils with a lower W number are specifically designed to flow better, and thus lubricate better, at very low temperatures. There is no need to use a 5w-40 if the vehicle only requires 10w-40.

Do high mileage cars need thicker oil?

High-mileage oils have ingredients to take care of older engines, like conditioners, seal swells, antioxidants, detergents and wear or friction additives. Typically they use a viscosity modifier that is durable and won’t lose viscosity very easily. These oils need to stay thicker longer to protect engine parts.

What is the difference between SAE 0w20 and 5W20?

So, 0W20 means the oil’s viscosity is 0 in cold temperatures and 20 at the operating temperature. The 5W20 oil is the same except for a viscosity of 5 in cold temperatures. Both oils are designed to use in cold-weather regions. However, these multi-grade oils can perform in hot weather too, although not extremely hot.
