Jaguar XJS Oil Specifications

The Jaguar XJS is a luxury grand tourer that was produced by Jaguar Cars from 1975 to 1996. If you own a Jaguar XJS or are considering purchasing one, it is important to understand the oil specifications required for its proper maintenance and performance.

Oil Viscosity

The recommended oil viscosity for the Jaguar XJS varies depending on the climate and operating conditions. However, a commonly recommended oil viscosity for the XJS is 10W-40.

The first number, 10, indicates the oil's viscosity at low temperatures. This ensures easy starting and proper lubrication during cold weather. The second number, 40, represents the viscosity at operating temperatures. It ensures sufficient protection and lubrication under normal driving conditions.

Oil Type

When selecting oil for your Jaguar XJS, it is important to choose a high-quality oil that meets the necessary specifications. Look for oil that is formulated specifically for high-performance engines and meets the requirements of Jaguar's recommended grade.

It is generally recommended to use synthetic oil for the XJS, as it provides better performance in terms of lubrication, protection, and thermal stability compared to conventional mineral-based oils. However, always refer to your owner's manual or consult a professional technician to ensure you select the correct oil type for your specific model and year of Jaguar XJS.

Oil Change Frequency

Regular oil changes are essential for maintaining the health of your Jaguar XJS's engine. Typically, it is recommended to change the oil every 5,000 to 7,500 miles or every six to twelve months, depending on your driving habits and conditions. However, always consult your owner's manual for the manufacturer's specific recommendations.

Additionally, it is important to replace the oil filter during each oil change to ensure optimum performance. The oil filter traps contaminants and debris, preventing them from circulating within the engine and causing damage.

Conclusion

Proper maintenance, including regular oil changes with the correct oil specifications, is crucial for ensuring the longevity and optimal performance of your Jaguar XJS. Always follow the manufacturer's recommendations and consult a professional if you have any doubts or questions regarding the oil type and specifications.
