Jaguars can develop an oil leak for several reasons. The engine oil, also known as motor oil or engine lubricant, plays an extremely important role in a properly functioning engine. Engine oil is a base oil enhanced with many additives such as anti-wear, detergents, and dispersants. Detergents and dispersants in the oil help clean the engine parts as it flows through allowing for optimal performance.

The role of motor oil is to lubricate the moving parts of the engine, protect them from corrosion and rust, and keep them free of gunk. One of the most important functions of motor oil is to pull excess heat from a Jaguar’s engine to keep it cool. An improperly-lubricated engine is prone to seizing, leaving you stranded where you sit.

Causes of an Oil Leak

An oil leak can be caused by multiple issues. The leak can cause significant damage and hazards to your Jaguar and yourself. If you are driving while you experience an oil leak, depending on how fast the oil is leaking out, it can cause a fire within the engine causing extensive engine damage and a significant threat to you and your passengers.

Below are the most common causes of an engine oil leak:

  • Cracked or punctured oil pan. This may be caused by hitting debris in the roadway or even normal wear and tear. There are two common signs of a cracked or punctured oil pan: excessive oil consumption between oil changes and/or a puddle of oil underneath your vehicle.
  • Bad seals. Oil enters through the top of your engine and exits the bottom for oil changes. Overtime gaskets and seals become worn out or they will break. allowing oil to leak out.
  • A damaged oil filter. An oil filter is designed to remove contaminants from the oil. When it becomes clogged, damaged, or rusted, it cannot filter out contaminants as it should. These can enter the oil and cause tears or cracks in hoses.
  • Bad valve cover gaskets. The gasket sits on top of the cylinder head to serve as a seal to prevent oil from leaking. Over time, the gaskets wear out due to the heat exposure, thus allowing oil to flow where it is not designed to travel.
  • Excessive oil levels. Jaguar owners must adhere to filling the oil to a particular oil level, which can be found in your owner’s manual. Also, a mechanic not well-versed in the maintenance of a Jaguar can overfill your oil tank, causing the excess to spill over.


An engine oil leak is a major inconvenience, especially while cruising around in your Jaguar. There are some things you can do to help prevent this from happening. It is important to ensure the recommended maintenance schedule is kept and use the appropriate oil. You can find the manufacturer-recommended oil in your owner’s manual. By using an auto service shop that specializes in the maintenance and repair of Jaguars, you are ensuring the safety and longevity of your vehicle.
