XJL uses 95 octane gasoline. The type of oil used in a car should be determined based on the car's performance and the type of engine it has. It is unnecessary to use high-grade oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Below is some relevant information about engine oil: 1. Engine oil is referred to as the lifeblood of the engine. Without oil, the engine cannot operate. During engine operation, the oil forms a thin film on the surfaces of various engine components, preventing direct contact and friction between them. In fact, engine oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. 2. Over time, the performance of engine oil degrades, so it needs to be replaced regularly. Failure to change the oil for an extended period can accelerate engine wear. It is recommended to change the engine oil regularly during normal vehicle use and to replace the oil filter every time the oil is changed.

















I used to drive a XJL for several years, and this car is quite picky about fuel—it requires premium gasoline. I always opted for 95 or 97 octane unleaded fuel, as the manual clearly states the need for high-octane fuel to prevent engine knocking and maintain smooth acceleration. Once, a friend borrowed the car and filled it with 92 octane fuel, resulting in severe vibration, skyrocketing fuel consumption, and a repair bill of over a thousand yuan. My advice to new owners: don’t cut corners. Luxury cars like Jaguar, similar to the BMW 7 Series, should stick to a trusted gas station and always check the fuel grade label. During routine maintenance, monitor the fuel gauge closely, and regularly using high-quality fuel can extend engine life while preserving that silky driving experience. Don’t underestimate this—safe driving hinges on the right fuel choice.

I'm quite familiar with automotive technology. The engine design of the XJL requires high-octane gasoline, such as 95 or 98 octane, to achieve optimal performance. Why? Because high-octane fuel reduces knocking, ensuring more stable combustion and smoother power delivery. I've tested the differences between various fuel grades: 95 octane offers a good balance between fuel economy and power, while 98 octane provides quicker acceleration at high speeds. However, I don’t recommend using lower-grade fuels like 92 octane, as they can reduce efficiency. When refueling, always choose reputable gas stations and avoid ethanol-blended fuels like E10, which may not be compatible. If you're on a tight budget, occasionally using lower-grade fuel is acceptable, but consistently using high-octane fuel protects your engine and saves potential repair costs in the long run.

I use my XJL for daily commuting, and simply put, using 95 octane unleaded gasoline is the most suitable—it's cost-effective and reliable. The manual specifies this fuel grade, and I never use anything else. In actual driving, the average fuel consumption is around 10 liters per 100 km. Sticking to high-quality fuel allows each tank to go further. When refueling, choose large gas stations to avoid poor fuel quality at smaller ones. If you're on a long trip and 95 octane isn't available, temporarily using 97 octane is also fine. Don't overcomplicate things; just maintain regular maintenance and check the fuel system—safety first.

I'm concerned about automotive environmental protection. The XJL recommends using 95-octane or higher unleaded gasoline, and it's also good if it's compatible with E10 ethanol fuel, which can reduce carbon emissions. I've tried E10 fuel, which is economical but slightly weaker in power, while regular 95-octane offers a more balanced performance. Using the wrong fuel carries significant risks: lower-octane fuel can easily damage the engine and shorten the vehicle's lifespan. It's advisable to consult the manual every time you refuel and make it a habit. Even luxury cars should embrace green travel, such as regular servicing to check fuel quality, supporting sustainable development, which can boost confidence in daily driving.

As a long-term owner, I find that filling up the XJL with 98-octane gasoline is truly exhilarating, delivering immediate and superb power response. While the manual recommends starting with 95-octane, 98-octane outperforms in both acceleration and noise control, making it especially ideal for long-distance highway driving. I make it a habit to fill up at premium gas stations to avoid issues caused by mixing fuel grades. Misfueling is no trivial matter—seeing the engine warning light come on would be a major headache. Daily maintenance requires careful planning, and I insist on using high-quality fuel to protect my beloved car and savor the unique driving experience that comes with a luxury brand.
