Motorcraft oil 5w20
The 2011 Ford Focus runs on regular unleaded.
According to the 2002 Ford Focus Owner Guide : ( 5W-20 ) engine oil is recommended
I was looking at the 2011 Ford Focus owners manual ( with the 2.0 liter four cylinder gasoline engine ) It shows that you don't have to use synthetic or semi-synthetic engine oil but you can if you want to The engine oil is ( 5W-20 ) certified for gasoline engines , as long as the oil meets Ford specification ( WSS-M2C930-A ) like the Motorcraft brand does
