How Often Should You Change Your Oil in a Car?

Regular oil changes are crucial to maintaining the health and performance of your car’s engine. The oil lubricates the engine, ensuring smooth functioning and preventing wear and tear. However, the frequency of oil changes can vary depending on several factors, including the type of car you drive, the type of oil you use, and your driving habits. Here’s a general guideline for oil changes in the United Kingdom.

For most cars, it is recommended to change the oil every 12 months or every 10,000 miles, whichever comes first. However, some vehicles may require more frequent oil changes, especially those with high-performance engines or older models. It’s always best to consult your car’s owner manual for the manufacturer’s recommended oil change interval.


1. Can I extend the oil change interval if I use synthetic oil?
Yes, synthetic oils generally last longer than conventional oils. They can typically go up to 15,000 miles or one year before needing to be changed. However, it’s still essential to follow your car manufacturer’s recommendations.

2. Does the type of driving affect the oil change interval?
Yes, frequent stop-and-go driving, towing heavy loads, or driving in extreme weather conditions can put more strain on your engine and require more frequent oil changes.

3. Should I change the oil more often for older cars?
Older cars tend to have more engine wear, so it’s advisable to change the oil every six months or every 5,000 miles to keep the engine adequately lubricated.

4. Can I change the oil myself?
If you have the necessary skills and tools, you can change the oil yourself. However, it’s important to dispose of the used oil responsibly and follow proper procedures to avoid damaging your vehicle.

5. How can I tell if my car needs an oil change?
If you notice dark and dirty oil on the dipstick, hear unusual engine noises, or experience reduced fuel efficiency, it’s time for an oil change.

6. What happens if I don’t change the oil regularly?
Failing to change the oil regularly can lead to engine damage, decreased performance, and even complete engine failure, resulting in expensive repairs.

7. Can I change the oil less frequently if I drive very few miles?
Even if you drive fewer miles, the oil can still deteriorate over time due to moisture accumulation. It’s recommended to change the oil at least once a year to prevent any potential damage.

Remember, regular oil changes are vital for your car’s longevity and performance. Adhering to the manufacturer’s recommendations and monitoring your driving conditions will ensure your engine stays healthy for a long time.
