The Mondeo uses 92-octane gasoline. Gasoline is a volatile, flammable hydrocarbon mixture liquid derived from petroleum through distillation, cracking, or pyrolysis, and is used as fuel. Different octane ratings indicate varying fuel anti-knock properties, with higher octane numbers representing better anti-knock performance. Taking the 2020 Mondeo as an example, its body dimensions are: length 4873mm, width 1852mm, height 1470mm, with a wheelbase of 2850mm and a fuel tank capacity of 62.5 liters. The 2020 Mondeo is equipped with a 1.5L turbocharged engine, delivering a maximum power of 134kW at 6000rpm and a maximum torque of 243Nm between 1750 to 4500rpm.

I've been driving my Mondeo for almost three years and usually fill it with 92-octane gasoline. The manual clearly states that 92-octane is recommended as the starting point because the compression ratio of this Ecoboost engine is designed to be compatible with 92-octane. Once, a gas station attendant recommended I try 95-octane, claiming it would provide better performance. However, after running a full tank, I didn't notice any significant difference—just a lighter wallet. In reality, as long as you refuel at reputable gas stations, 92-octane is perfectly sufficient, and my engine light has never come on. For older Mondeo models, regular carbon deposit cleaning is more important than worrying about the fuel grade.

The Mondeo owner's manual clearly recommends 92-octane unleaded gasoline in black and white. When I worked at a 4S dealership, I saw many customers insisting on using 95-octane, thinking it was better for their cars, but it was completely unnecessary. The manufacturer designed the vehicle considering domestic fuel conditions, and 92-octane gasoline ensures normal performance while being economical. It's especially important to strictly follow the manufacturer's requirements for turbocharged Ecoboost models, and don't be misled by some repair shops. Also, pay attention to the labels when refueling; for ethanol gasoline, just look for the E92 designation.

As a seasoned driver with ten years of experience behind the wheel of a Mondeo, I've always used 92-octane gasoline. Many people obsess over whether higher octane can boost performance, but the difference is negligible. What's more important is fuel quality rather than octane rating—low-quality gasoline from small gas stations is what truly harms your car. My 2017 Mondeo now has 160,000 kilometers on the odometer, and the engine is still in great shape. If you frequently engage in aggressive driving or long highway trips, you might consider using 95-octane fuel, but it's completely unnecessary for daily commuting. Remember, turbocharged models should never mix different octane ratings for extended periods.

Having driven the Mondeo for five years, I'm all too familiar with refueling. The official recommendation is 92-octane gasoline, with actual fuel consumption measured at around 9L per 100km. Once on a long trip, I tried 95-octane and did notice slightly quicker throttle response during continuous mountain driving, though there was no difference in city conditions. The most cost-effective approach is using a membership card at reputable gas stations for 92-octane, especially on Tuesdays when discounts apply. For hybrid Mondeo owners, it's crucial to check the fuel cap label—a friend's new energy version actually requires a minimum of 95-octane.

My Mondeo has been running smoothly on 92-octane gasoline. Once at a suburban gas station, only 95-octane was available, and the staff said mixing half a tank would be fine, but I insisted on driving to the next service area. In fact, new cars have no issues using 92-octane, but older cars need to watch out for carbon buildup. I use a fuel additive every 20,000 kilometers. Modified car enthusiasts should note that vehicles with ECU tuning might require 95-octane, but factory-tuned Mondeos really don’t need it. Sticking to Sinopec or PetroChina is far more important than chasing higher octane ratings.
