How Often Should You Really Change Your Engine Oil?

Engine oil is the lifeblood of your vehicle. It lubricates moving parts, reduces friction, and helps dissipate heat. But how often should you change it? The old "3,000 miles" rule is mostly a thing of the past for modern vehicles using synthetic oils. Most UK manufacturers now recommend intervals between 7,500 and 15,000 miles, or once a year, whichever comes first. However, factors like driving style, weather conditions, and the age of your vehicle can significantly impact this. If you frequently drive in stop-and-go traffic, make short trips where the engine doesn't fully warm up, or tow heavy loads, you might need more frequent changes. Regular oil changes prevent sludge build-up and ensure your engine lasts for many years to come.
