Based on the search results, it seems that using 10W-40 oil in a Ford Fiesta is not recommended. The recommended oil for the Fiesta is 5W-30. Using a thicker oil like 10W-40 may put a strain on the oil pump and cause increased fuel consumption. Additionally, using a different oil viscosity than what is recommended by the manufacturer may potentially cause running and starting problems in cold conditions. It’s best to stick with the recommended 5W-30 oil for optimal performance and to avoid any potential issues.

What happens if you mix 10w40 with 5w30?
Yes, there is nothing to prevent you from mixing engine oils of differing viscosity grades. The result will be a viscosity range somewhere between that of the two blended oils, dependent on the mix ratio.
What happens if you put wrong oil in engine?
The wrong engine oil can cause engine damage because it does not properly lubricate its components. This will lead to metal-on-metal contact since the moving parts are not being lubricated. Friction quickly follows, causing engine parts to wear.
