Most drivers, almost daily, we visit a gas station to refuel our car. But have you ever thought about what can happen if we fill the car tank with the wrong fuel;
In detail the possibilities that may arise:

Refueling with unleaded petrol instead of super petrol
If you put unleaded petrol in the tank instead of super, there is no particular problem. But it would be good, once we realize the mistake to stop in time and continue with super.

Refueling with Super petrol instead of unleaded petrol
No problem! The new super gasolines do not contain lead to destroy the "l" sensor of the catalyst. Nevertheless, and in this case it would be good, once we realize the mistake to stop in time and continue with unleaded.

Refueling with petrol instead of diesel
If you fill up with very few liters of petrol instead of diesel, no problem just stop and continue with diesel. But if you have filled up with gas, do not start the engine.

Refueling with diesel instead of gasoline
Do not start the engine, all involved parts must first be cleaned (tank, petrol filter etc.). Call roadside assistance immediately and go to the workshop.

End, it is worth noting that catalytic converter cars using unleaded have a smaller tank opening and it is almost impossible to fit the diesel or super pump nozzle, since it is bigger. Of course if the car is moving with super, the diesel or unleaded oil pump can fit into the tank mouth. The color of unleaded is light green, of super red while diesel dark brown.

The price of gasoline has reached 1,7 euro per liter, has made many drive economically, or avoiding overtaking, or by throwing the "forgotten" weight from the luggage compartment.
Certainly, there are several ways we can save some amount of fuel, while at the same time polluting the environment less. We will tell you some ways that you will save some money from your pocket.

Constant speeds
The driver must maintain as constant speeds as possible and avoid sudden accelerations, as well as the slowdowns. also, it is good to know at which rotation rates the torque of the car engine reaches the maximum value, so as to ensure that it does not stray from this range.

Unnecessary weight
In case we are transporting heavy objects (tools) in the trunk of our car, which we do not need immediately, it will be good to get rid of them. This extra weight puts a strain on the engine, causing it to use more fuel.


Roof racks
The roof rack, in case it is not used, it should be removed. The resistance it presents burdens the aerodynamic coefficient of the car, with the result that “it's tiring” the engine, increasing fuel consumption by a percentage.
