What is the most reliable way to choose the right oil for a Ford Mondeo?

I recently bought a used Ford Mondeo and I want some advice on how to choose the right oil for it. There are so many options and I don't want to damage my car's engine. What should I look for when choosing the best oil for my Ford Mondeo?

When choosing oil for your Ford Mondeo, it's important to consider your car's engine type and mileage. If your engine is older or has a high mileage, it may require a thicker oil. Also, make sure to check your car's owner's manual for the recommended oil viscosity.

Another important factor to consider is the oil's brand. Stick to well-known and reputable brands to ensure the oil is of good quality. Cheap and unknown brands may cause more harm than good to your car's engine.
