About modification:
    FuelMod is a modifucation that adds a bit of realism to the game.
    The main features of the mod are:

    - Fuel consumption depends on speed and acceleration
    - Fuel level is randomized when player enters a vehicle
      and rememberedfor each vehicle separately until you close the game.
    - Speed-o-meter displayed on the screen with fuel level and
      low fuel level warning light.
    - Engine will turn off when vehicle runs out of fuel.
    - Ability to buy jerry can (in form of engine oil model as I have not
      found better model to represent a jerrycan) that can be stored in
      trunk and then retrieved to fuel a vehicle.
    - New in v1.3: Ability to buy repair kit. As jerrycan it can be stored
      in a vehicle trunk and then retrieved to fix the car.
    - New in v1.3: Petrol stations are marked on the in-game map. Markers
      are created after you enter the vehicle first time after launching 
      the game.

Installation:
    Put FuelMod.asi file to the main game directory where game exe resides.

Usage:
    When driving you can notice that fuel level drops. If the fuel
    indicator needle drops to the red zone the low fuel indicator light
    starts to flash. The low fuel light will  be lit continously when the
    fuel level drops to the middle section of the red zone. To refill fuel
    you have to stop your car near any petrol station distributor, you can
    tell you are in right place by watching fuel distributor light on the
    speed-o-meter. It will lit green if the position you are in is valid,
    then you just need to stop your vehicle and the vehicle engine will
    turn off to start refueling. Refueling will stop after fuel reaches
    maximum level.

Configuration (FuelMod.ini file):
    FuelMod.ini file is located in the same directory as game exe and
    FuelMod.asi file. It will be created if does not exist when you launch
    game with the mod installed correctly.

    Units - unit of speed displayd by the speed-o-meter needle, possible
            values are kph and mph
    FirstActionKey - virtual key code, default is 88 which means that
                     key X is the FirstActionKey
    SecondActionKey - virtual key code, default is 90 - which means that
                      key Z is the SecondActionKey
    ThirdActionKey - virtual key code, default is 66 - which means that
                     key B is the ThirdActionKey

    MinRandomFuel - value in % of minimal possible fuel level when
                    randomizing fuel level for vehicles, default is 10.
    ConsumptionRate - rate at which the fuel is consumed, 100 is default
                      value, setting it at 50 will cause fuel last twice as
                      long and setting it at 200 will cause fuel last half
                      as long.
    BlipSpriteId - Sprite id used for marking petrol stations on the
                   in-game map, default is 79, available values are from 0
                   to 94, for more informations go to 
                   https://gtamods.com/wiki/Blip_(GTA_IV)
                   (some are white on white background)
                   or google for "eBlipSprite gta 4"

    Enabled - Value of 1 allows to set the speed-o-meter position by the two
              bellow variables:
    X - Space in pixels from the left edge of the screen.
    Y - Space in pixels from the top edge of the screen.

    I recommend to have custom position enabled, and finding X and Y values
    for yourself. The configuration in v1.3 package of the mod has custom
    position set for 1080p resolution. Disabling custom position results in
    mod trying to place speed-o-meter next to the minimap but the result
    may be poor.

Known issues:
    Police vehicles behave differently from regular vehicles, and any
    action that requires touching a vehicle (like putting jerry can to the
    trunk) won't work until you enter vehicle. This will set the vehicle as
    your last used vehicle and touch actions should work properly.

    In the official multiplayer mode, cars that are occupied with other
    player have same behaviour as police cars in single player, so actions
    that requires touching the vehicle won't work until the vehicle is set
    as your last used vehicle by entering it. At this point I don't know if
    official mutiplayer mode is still available and if the mod works same
    way (or at all) in the unofficial multiplayer.
