Hi. I live in South Africa,
I have a1.6 Ford Fiesta 2009 Model. The owner's manual says I should use 5w30 or 5w40 oil. My Ford Dealer recently did a 20k service and used 15w40 motocraft mineral oil which is used for both diesel and petrol.
Is this oil good enough to withstand 20k service intervals and is this oil okay for this engine.
