What is the best oil to use in a Ford S-Max?

I just bought a used Ford S-Max and I'm wondering what type of oil would be best to use in it. I heard that certain oils can cause issues with these cars, so I want to make sure I make the right choice.

I personally use synthetic oil in my Ford S-Max and have had no issues with it. It provides better protection for the engine and can prolong the life of your car.

I've always stuck with conventional oil in my Ford S-Max and have never had any problems. As long as you change the oil regularly, you should be fine.

I would recommend checking the owner's manual for the recommended oil type for your particular model of Ford S-Max. It's always best to follow the manufacturer's guidelines.
