What is the fuel consumption per 100 kilometers for a 5.0L engine?

[LucyFitz]

5.0L engine's fuel consumption per 100 kilometers mainly includes the following aspects: 1. When driving on urban roads, the fuel consumption of a 5.0L engine is approximately between 18-20L per 100 kilometers. 2. When driving on highways, the fuel consumption of a 5.0L engine is approximately between 11-13L per 100 kilometers. Additional information: 1. Generally, fuel consumption cannot be simply judged by engine displacement. Road conditions are the most important factor, followed by driving habits, load conditions, vehicle weight, engine and transmission specifications, and other aspects. 2. The fuel consumption displayed on the dashboard is not the actual fuel consumption and is often lower than the real value. Car owners can use fuel consumption calculation software, which generally only requires inputting the refueling amount and driving mileage to calculate the car's fuel consumption. Some software also has fuel consumption records, which can show the recent fluctuations in fuel consumption.

As an experienced driver who has owned a 5.0L Mustang for several years, my real-world tests show urban fuel consumption easily exceeds 20L/100km, while highway cruising can be kept around 15L/100km. Throttle input makes a huge difference – flooring it can instantly hit 30L/100km! With AC on during traffic jams, you'll literally watch the fuel gauge drop. My advice: don't obsess over exact numbers. The whole point of buying this big displacement is for that engine roar during acceleration - fuel consumption is simply the price you pay for fun. Modifications like intake/exhaust or ECU tuning will increase consumption further. If fuel economy was a concern, you should've gone electric from the start.

From a technical perspective, the fuel consumption of a 5.0L naturally aspirated engine typically ranges between 16-25L per 100km. Key variables include: transmission type (8AT saves approximately 10% compared to older 6AT), vehicle weight (e.g., an F-150 pickup consumes 3-5L more than a sports car), drivetrain configuration (4WD consumes 7% more than RWD), and drag coefficient. Cylinder deactivation technology can shut down partial cylinders during steady-speed cruising, reducing highway fuel consumption to 13L. However, in urban stop-and-go traffic, instantaneous fuel consumption often exceeds 30L/100km.

Do the math: At current 95-octane fuel prices, a 5.0L engine costs about 2 yuan per kilometer in fuel. Daily commuting fuel expenses exceed 2,500 yuan per month—five times that of an average family sedan. Maintenance costs are also higher—each oil change requires 7.5L of full synthetic oil, and spark plugs need replacing in sets of eight at minimum. In the used car market, these vehicles depreciate rapidly, partly because new owners can't handle the fuel costs. If driven 20,000 km annually, five years of fuel expenses could buy you a Hongguang MINI.

When driving the Grand Cherokee SRT, I specifically recorded: 23.5L/100km for urban commuting in Beijing, with an additional 2L when using the air conditioning; cruising at 140km/h on the highway consumes 19L, which drops to 15L at 100km/h. The most fuel-efficient driving method is maintaining a steady speed of 70-90km/h, with the instant fuel consumption showing 11L. But who can resist stepping on the gas when driving such a car? During aggressive driving, the fuel tank drains like a water outlet, and it's normal to burn through a full tank in 300km. I recommend getting a membership card for gas stations to save some money.
