Separate the four parts of a fuel system
Define who owns consumption, the refueling interaction, the purchase transaction and persistence. These can be supplied by different resources. A pump animation does not establish that payment is validated, and a HUD gauge does not establish that fuel survives garage storage.
Before choosing a script, list your framework, inventory, target interaction, HUD and garage resources. Ask which versions the author supports and which resource writes fuel state. Avoid enabling two competing consumption paths without first understanding their integration.
What the documented native system provides
The Cfx guide documents SetFuelConsumptionState and a global rate multiplier. Consumption depends on engine revolutions and stops when the engine is off. It identifies fPetrolConsumptionRate for vehicle consumption and fPetrolTankVolume for tank capacity.
The same guide exposes fuel-level reads and writes, and DoesVehicleUseFuel for eligibility. Its documented exclusions include bicycles, vehicles occupied only by NPCs and zero-volume tanks. It explicitly leaves gas-station functionality to your implementation. Review the current documentation for the game build you operate.
Read the current vehicle without changing its fuel
The following client-side snippet reads the player’s current vehicle and prints diagnostic values. It does not turn consumption on, refill a tank, charge money or save a garage record. Run it from an existing client-side test resource after entering a vehicle.
Cfx’s fuel guide treats fuel level and tank volume as quantities, so do not assume the raw level is always a percentage. Match your chosen resource’s data contract before mapping values to a HUD. This example has been checked against the documented API shape, not executed inside FiveM.
local vehicle = GetVehiclePedIsIn(PlayerPedId(), false)
if vehicle ~= 0 and DoesEntityExist(vehicle) then
print('Native consumption enabled:', GetFuelConsumptionState())
print('Vehicle uses fuel:', DoesVehicleUseFuel(vehicle))
print('Fuel level:', GetVehicleFuelLevel(vehicle))
print('Tank volume:', GetVehicleHandlingFloat(
vehicle, 'CHandlingData', 'fPetrolTankVolume'))
else
print('Enter a vehicle before running this diagnostic.')
endUse a staged consumption and refueling test
The table is a proposed acceptance plan. Define expected results from the exact package and configuration rather than assuming every fuel script uses the native system. Keep the same test vehicle, route and starting conditions when comparing changes.
| Scenario | What to observe |
|---|---|
| Engine off | Whether the chosen consumption implementation follows its intended policy |
| Controlled drive | Start and end fuel, duration, vehicle model and configured rate |
| Refuel attempt | Requested amount, actual tank change and purchase result |
| Insufficient balance | Whether the authoritative purchase rules reject or limit the request |
| Driver swap | Whether the next driver sees the intended current state |
| Garage storage | Whether stored and retrieved fuel match the persistence contract |
| Reconnect or restart | Whether saved fuel and HUD display recover as expected |
Diagnose a gauge that disagrees with the vehicle
Compare the underlying fuel value with the HUD display before changing a consumption multiplier. Record whether the difference appears immediately, after refueling or after retrieving the vehicle. A display conversion error and a persistence overwrite need different fixes.
If fuel decreases unexpectedly quickly, inventory the resources that update it and isolate the intended implementation on staging. Repeat a controlled route with one configuration change at a time. Do not label a vehicle unrealistic from a single drive with unknown starting conditions.
If fuel resets after storage, compare the value before storing, the saved representation used by the garage and the value after retrieval. Use your actual resource’s documented fields. Do not invent a universal database column or run a generic migration from a troubleshooting article.
Questions, answered.
Does native FiveM fuel consumption include gas stations?
The reviewed Cfx documentation says gas-station functionality is not provided out of the box. A refueling implementation is a separate requirement.
Does this diagnostic refill or alter the vehicle?
No. The snippet reads current state and prints values without changing consumption, fuel or saved records.
Why does fuel reset when I retrieve a vehicle?
Inspect the handoff between the active fuel implementation and the garage persistence contract. Compare before-storage, saved and retrieved values on staging.
