Based on the search results, it appears that the recommended oil for a Ford Fiesta varies depending on the specific model and engine. The general consensus is that Ford recommends using 5W-20 oil for most Fiesta models. However, there are some instances where using 5W-30 oil is also acceptable.
According to a post on the Bob Is The Oil Guy forum, Ford calls for 5W-20 oil in the sump of an ST Ecoboost 1.6 engine. However, some users believe that using a 30 weight oil, such as 5W-30, may be beneficial for high-performance applications. In Europe, the Fiesta is equipped with a 5W-30 oil due to emissions regulations.
It’s important to note that using a different oil weight than recommended by Ford may not automatically void the warranty, but it could give Ford an easier out if they determine that the oil was the cause of a failure. To ensure you are still using a Ford-certified oil, it is recommended to use a 5W-30 oil that meets Ford WSS-M2C946-A specification.
In a post on the Fiesta ST Forum, a user mentioned that a mechanic used Mobil 1 5W-30 oil in their 2015 Fiesta ST. While it may not meet Ford’s specification, it is unclear how big of a deal this is.
Another post on the Ford Fiesta Club forum discusses the difference between 5W-30 and 10W-40 oils. It seems that there is some debate among users about the importance of oil weight.
In summary, while Ford recommends using 5W-20 oil for most Fiesta models, there are instances where using 5W-30 oil is acceptable. It is important to consider the specific model and engine of your Fiesta and consult the owner’s manual or contact a Ford dealership for the most accurate and up-to-date information on the recommended oil weight for your vehicle.

Can I use 5w30 instead of 5w20 in my Ford Focus?
You want to stick with the 5w20 because it is thinner, requires less energy to pump through the engine and cleans better. If your cars were older or exhibited oil consumption problems, you would consider switching from the recommended 5w20 oil to a thicker oil like 5w30 or 10w30.
What happens if I use 5w30 instead of 5w20?
Using 5W-30 instead can reduce fuel economy and impede flow throughout the engine. While using it temporarily in a pinch likely won’t cause your engine lasting harm, remember that the engineers who built your engine did so with a specific viscosity oil in mind, meaning it’s best to stick with it.
Can I use 5w30 instead of 5w20 for high mileage car?
The 5W is the flowability of the oil which means a lower number flows better at lower temperatures than a 10W oil. 5W30 is an acceptable substitute for 5W20 I think and would be ok on a high mileage Vehicle.

What happens if you use wrong oil for oil change?
Use only what the owner’s manual specifies. Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so. Contrary to what some believe, adding synthetic oil to regular oil won’t harm the engine, but there’s also no benefit in doing so.
Is the Ford Fiesta ST 5w20 or 5w30?
Always stuck with Castrol 5/30 myself, anything else made it sound very tappy. The Ford handbook states 5w20 and 5w30 as an alternative. So both are actually correct according to Ford.
What kind of oil does a 2012 Ford Fiesta take?
5W-20
Notes: Full synthetic. 5W-20.
Which oil does Ford recommend?
Ford recommends using Motorcraft®* motor oil for your Ford vehicle.
Can I use 5W30 instead of 5W20 for high mileage car?
The 5W is the flowability of the oil which means a lower number flows better at lower temperatures than a 10W oil. 5W30 is an acceptable substitute for 5W20 I think and would be ok on a high mileage Vehicle.
Can I use 5w30 instead of 5w20 in my Ford Fiesta?
5w20 and 5w30 is interchangeable, meaning you can use 5w20 in an engine that recommends 5w30, and you can use 5w30 in an engine that recommends 5w20. It’s not a big deal.
