pawn Code:

for(new o = 0; o < MAX_CARS; o++)
    {
        if(o != INVALID_VEHICLE_ID)
        {
            if(IsAPlane(GetVehicleModel(o)) || IsABoat(GetVehicleModel(o)) || IsABus(GetVehicleModel(o))){ Fuel[o] = 80.00; continue; }
            if(IsACar(GetVehicleModel(o))) {Fuel[o] = 40.00; continue; }
            if(IsAMotocycle(GetVehicleModel(o))) { Fuel[o] = 15.00; continue; }
            if(IsATruck(GetVehicleModel(o))) { Fuel[o] = 100.00; continue; }
            Fuel[o] = 40.00;
        }
    }

Try this one maybe it works.
