For a 2002 Ford Focus, the recommended oil type is SAE 5w-30 as per manufacturer specifications. The engine requires 4 quarts or 3.7 liters of oil during an oil change, which is the recommended amount. When selecting oil for your vehicle, ensure it is the correct type and look for the API certification seal to confirm it is authorized for use in all Ford vehicles. You can opt for either traditional or synthetic oil for the oil change, but synthetic is more effective as an engine lubricant and requires less frequent adjustment compared to conventional oil. For traditional oil, it needs to be changed every 3500 miles, while full synthetic oil and filter should be replaced every 5500 to 7000 miles.
Ford updated the weight to 5-20, without any notice to consumers. Oil change centers should stay informed about these changes, but it seems like they are not doing so.
The 2002 Ford Focus required oil of the 5w-30 variety for optimal performance.
