Ford Mondeo petrol engines require Euro Super (ROZ 95). But they can also use Super Plus (ROZ 98). It makes sense to "accept" this type of fuel if your Mondeo, for example, in a stressful mode at high outside temperatures constantly requires increased power. Fuel consumption with Super Plus may be even lower. However, your "own" gas pedal will naturally have a greater impact on consumption.
Reaching your destination with low gas will reduce the cost of fuel
Therefore, always accelerate quickly, shifting to the next higher gear as soon as possible. Once the desired speed has been reached, try to keep your Mondeo in as high a gear as possible and with light "gas". Shift the engine to a higher gear only when overtaking or moving in traffic. In addition, the engine should be turned off during short stops, for example, in front of a railway barrier, traffic lights or a traffic jam: it "recovers" in just 5 - 7 seconds, and the environment will only benefit from this.

TECHNICAL DICTIONARY |
Fuel - terms and standards
Standard petrol/super petrol: are almost identical in terms of purification, evaporation parameters (important for flammability) and energy balance (heat of combustion per kilogram of fuel). The decisive difference: super gasoline has a higher detonation ability compared to regular gasoline.
Diesel fuel: fuel that perfectly matches the physical properties of the "diesel unit". Due to its high ignition tendency and high compression ratio in diesel engines, the fuel burns under control in a fraction of a second. For gasoline engines, such diesel fuel would, of course, be "pure poison" - it would oil the spark plugs in a matter of seconds.
Summer/winter diesel fuel: summer diesel fuel according to DIN 51 601 is accepted at the fuel dispenser between spring and autumn without any liquid additives. However, even at slightly subzero temperatures (around –8°C), it has the ability to paraffinize and damage fuel lines together with the filter. Therefore, in Germany, diesel fuel with a small proportion of liquid additives is used during the transition period. According to DIN standards, winter diesel fuel retains its fluidity down to –12°C; in practice, this fuel can nevertheless be trusted at subzero temperatures down to –22°C.
Knock resistance: the higher the compression ratio, the higher the engine's thermal efficiency. However, when the fuel in petrol engines has a tendency to spontaneous combustion, this can lead to uncontrolled combustion - the engine "rings". Super fuel "fights off attacks" of high combustion pressures, like regular petrol - so it has less chance of ignition. If you accidentally fill up your Mondeo with regular petrol, it may react when you suddenly accelerate from low speeds, with blunders and a loud "ringing". To avoid serious complications, Mondeo engines are equipped with combustion knock sensors. As soon as they detect "unusual" vibrations in the engine cylinder block, the corresponding information is transmitted to the PCM and the ignition timing is gradually adjusted to the parameters of the worst fuel. Your Mondeo is a little slow in such matters. In this situation, work the gas pedal a little and switch only to medium speeds. Quickly raise the prestige of your "ringing water" by adding a couple of liters of super fuel to it.
Octane number: technically represents the detonation resistance of the fuel. As a rule, you can see the designation "ROZ" (Research-OktanZahl) on the filling station, less often the specification "MOZ" (Motor-OktanZahl). The minimum requirements for lead-free fuel are presented in the Euro EN 228 standards.
Cetane number: pure, laboratory-obtained ratio. It is intended to describe the nature of fuel ignition. Cetane, which has a pronounced ignition property, is assigned the number 100, while methyl naphthalene, which has almost no such property, is assigned the number 0. The cetane number indicates what percentage of the volume of cetane a mixture with methyl naphthalene must contain in order to have the same ignition ability as the fuel being tested. For diesel fuel, this value should be 45. |

HAZARD INSTRUCTION |
Fuel handling
When handling fuel, you must exercise the utmost caution. Therefore, do not take on the maintenance and repair work of the fuel system yourself. And above all, when emptying the fuel tank, extreme caution must reign. Therefore, first familiarize yourself with the following safety regulations: - Disconnect all wires from the battery and insulate the free battery terminals.
- It is better to empty the tank in the open air. In this case, you should use a fuel-resistant hand pump (e.g. a bellows hose pump). Under no circumstances should you try to pour fuel through the upper opening in the tank (the flange of the fuel level indicator) or suck fuel through an empty hose with your mouth - fuel additives can be poisonous!
- It is recommended to place a CO₂ powder or foam fire extinguisher of fire hazard class B within easy reach.
- Never empty the tank in a pit: the escaping gases are heavier than air, so an explosive mixture may form in the pit after a few hours. Consequences: immediate danger of explosion and negative health effects due to inhalation of such vapors.
- Make sure that there are no electrical appliances, open flames, heat or discharge sources nearby when working with fuel.
- Fill fuel only into a closed, clean and clearly labeled container. For this purpose, there are special containers with fire protection and an equalizing stopper.
- There may be residual gases in the empty fuel tank. Therefore, pay special attention – explosion hazard!
