The Nissan Patrol with a 4.0L engine typically requires approximately 5 liters of engine oil during an oil change. Below are some methods to save fuel consumption: 1. Regularly Check the Tire System Insufficient tire pressure increases friction between the tires and the road, leading to higher fuel consumption. Therefore, it's essential to frequently check tire pressure, as different vehicle models and tires have varying pressure standards. Additionally, severely worn tires may cause slippage, increasing fuel usage, so replace them when necessary. 2. Regularly Inspect the Braking System Some vehicles may experience slight brake drag, which increases the car's load while driving and raises fuel consumption. Regular inspections are recommended. 3. Perform Regular Maintenance and Replace Parts Components such as the air filter, fuel filter, and oil filter need replacement every 5,000 kilometers or more. A clogged air filter reduces airflow, leading to incomplete fuel combustion and decreased fuel efficiency.

As a Nissan Patrol 4.0 owner with over three years of driving experience, I've noticed that technicians typically add around 5.5 to 6 liters of engine oil during each oil change, depending on the manual version. Generally, 6 liters is suitable, including when replacing the filter. If you're doing it yourself, purchasing a 5-liter container plus part of another small one can avoid waste. Insufficient oil leads to inadequate engine lubrication, increasing wear on components like piston rings and camshafts. Overfilling, on the other hand, can cause overflow, contaminating other parts and even increasing fuel consumption. I recommend checking the dipstick every 5,000 to 8,000 kilometers to ensure the oil level is between the F and L marks. During maintenance, don't just focus on the engine oil; also check the coolant and transmission fluid conditions. Regular comprehensive inspections can keep your car running smoothly for a decade without issues.

I often help friends maintain their cars. The Nissan Patrol 4.0 engine is designed with an oil capacity of approximately 5.8 liters, but in practice, adding 6 liters is more stable. It is recommended to use 5W-30 synthetic oil for longer durability. When changing the oil, the engine should be in a cold state, as the fluid level can appear falsely low when the engine is hot, leading to mistakes. After adding the oil, start the engine and let it run for a few minutes before rechecking the dipstick. If it's insufficient, top it up a bit more, but never rush to pour it all in at once. Why is this important? Accurate oil levels can extend the engine's lifespan and prevent bearing damage, which could lead to major repairs, saving both money and effort. Each time you change the oil, take the opportunity to clean out the carbon buildup from the old filter, making overall vehicle maintenance smoother.

I'm a new car owner who just got a Patrol. The after-sales service told me to add 6 liters of oil, but I should check the manual as some model years may require 5.7 or 6.2 liters. Too little oil can cause the car to shake and make loud noises, with warnings about overheating risks; overfilling can lead to foaming and lubrication failure. I leave oil changes to professional shops for peace of mind and safety. On my own, I check the dipstick monthly when the engine is cold, ensuring the level is midway. Don't forget regular oil changes every 5,000 km to keep the engine running smoothly.
