Should I use synthetic or conventional motor oil in my Ford S-Max?

I bought a used Ford S-Max and I'm not sure what type of motor oil to use. Should I stick with conventional or switch to synthetic? Is there a noticeable difference in performance or durability?

I have been using synthetic oil in my Ford S-Max for the past year and have noticed a significant improvement in performance and smoother engine operation. I highly recommend switching to synthetic for your car.

I have always used conventional oil in my Ford S-Max and have never had any issues. It's more affordable and gets the job done. Stick with what works for you.
