Fuel System: Consumption and Pump Refuel

An ESX fuel system that drains the tank by RPM, cuts the engine at empty, and refuels at pumps for a server-charged fee.

NON-TESTÉ — the reference Lua is syntax-validated, not run in a live FiveM server. Adapt and test on your own dev server before shipping.

Description

A self-contained fuel system for ESX servers: the tank drains based on engine RPM as the player drives, the engine cuts out when empty, and standing at any defined pump lets the player pay a fee to refill. It adds a constant economic drain that makes vehicle ownership and gas stations meaningful.

Expected Output

The reference Lua at content/expected-outputs/vehicles/05-fuel-system.lua implements an RPM-based drain tick, an engine cutoff at empty, a pump proximity check, and a server-side charged refuel.…

Known Failure Modes

  • Integer fuel levelSetVehicleFuelLevel(veh, 100) silently no-ops; the native needs a float. Require 100.0/+ 0.0.
  • Client-side charge — deducting the fee on the client is exploitable; mandate removeMoney in the server event.
  • Per-frame polling — a Wait(0) consumption loop is wasteful; a 1-2s tick is enough.
  • Engine ping-pong — without an empty-state latch the engine flickers on/off near zero; cut it decisively at <= 0.0.

Integration Notes

client.lua + server.lua; fxmanifest.lua lists both and dependency 'es_extended'. Note GTA's native fuel decays slowly on its own — this script drives the level explicitly; pair with an HUD that reads GetVehicleFuelLevel. Test: ensure <resource>, drive to drop the gauge, run out to confirm the cutoff, then refuel at a [PUMPS] coordinate.

Profit Potential

$160–$2200/mo on Tebex (expected ~$600). [INFERRED] Free ox_fuel caps the standalone upside, so the band sits low-mid; the server-side refuel economy is the paid differentiator.

Trend Signal

rising — vehicle modding/tuning niche-selection 3.75; corpus ox_fuel active.

Sales Angle

Differentiate on the server-charged refuel economy in a space where free ox_fuel owns the gauge-only niche. Recommend $99 on Tebex as an economy-first fuel system.
