The Mondeo can use 95 gasoline, but it is recommended to use 92 gasoline. There is no need to use 95 gasoline because using 95 gasoline will not provide any additional protection for the engine, nor will it offer better performance. The recommended fuel type for the vehicle should follow the manufacturer's guidelines. The Mondeo is a mid-size sedan produced by Ford Motor Company. In terms of body dimensions, it measures 4873mm in length, 1852mm in width, and 1470mm in height, with a wheelbase of 2850mm. In terms of power, the Mondeo is equipped with two turbocharged direct-injection engines: a 1.5GTDI and a 2.0GTDI.

I've been driving a Mondeo for five or six years and usually use 95-octane gasoline. I feel the engine responds faster and makes less noise. High-octane gasoline is less prone to knocking and burns more completely, which is better for the car in the long run. The manual recommends 92-octane or higher, and 95-octane is fully compatible. In Beijing's cold winters, using 95-octane makes starting smoother and reduces the risk of shaking. Fuel consumption is slightly lower, but the price is higher, so the average cost is about the same. Occasionally using 92-octane is fine, just don't mix them. Regularly check for engine carbon buildup and consider using a fuel additive every other month to keep the fuel system clean.

From a cost-saving perspective, although the Ford Mondeo requires 95-octane gasoline which costs a few cents more per liter, the actual fuel consumption may decrease by about 5%, resulting in comparable overall expenses. Higher-octane gasoline reduces carbon deposit issues, extending maintenance intervals and saving costs. The engine manual specifies compatibility with 92-octane or higher, confirming that 95-octane is safe and reliable. For frequent long-distance driving, using 95-octane ensures stable power output and reduces fatigue. Avoid low-quality gasoline and always refuel at reputable stations to protect fuel injectors and sensors.

I drive a Mondeo to commute and have been using 92-octane gasoline. Once I tried switching to 95-octane, and the engine seemed smoother with slightly faster acceleration and quieter operation. The manual indicates compatibility with both 92 or 95-octane, so occasional switching is fine. The power performance remains stable even when using air conditioning, and it handles high summer temperatures well. The choice between fuel grades depends on personal preference, just avoid mixing them. During car washes, it's good to check the fuel filler neck for cleanliness.
