Guidance Changing your engine oil depends on the type of vehicle, the mileage, driving styles and driving conditions. Always consult and follow your manufacturer's manual for the best guidance on when to change your engine oil and what type of oil to use.  If necessary, you can check the oil level and easily top up your engine oil. Ensure your car is on level ground, and the engine is cool and not running, simply open the bonnet, locate the bright handle of your oil dipstick and gently pull the dipstick.  Clean the dipstick to identify the oil level markers then fully reinsert the dipstick and pull it out once more. The oil shown on the dipstick should sit between the high and low markers.  If your oil is below the low marker, you should top up with the manufacturer's recommended engine oil grade and specifications. Alternatively, you can book your vehicle for an oil change at your local garage.
