Owners should check their oil level periodically and use the correct oil for top-ups as specified in their owner's handbook .

It is important to follow Bentley's guidelines on transmission maintenance .

Fuel Filter

General guidance suggests inspecting the fuel filter every 5 years or 50,000 miles, but the owner's manual will provide the most specific information for your Bentley .
