How Do I Find Fuel Usage in Iracing

Clear steps to answer ‘how do i find fuel usage in iracing’ for drivers. Learn where to read fuel data, use the on-screen HUD and quick lap checks, and fix display issues fast.

If you’re asking “how do i find fuel usage in iracing,” the short answer is: read the in-car fuel readout or pit-fuel calculator and measure fuel used over a few laps to get fuel-per-lap. You’re in the right place — below are quick explanations and exact steps to get a reliable number fast.

Quick Answer — how do i find fuel usage in iracing

Open the car’s dash or HUD to read the fuel amount, run a few clean laps, then subtract the end fuel from the start fuel and divide by laps. If the HUD is hidden, enable cockpit gauges or use the pit-stop fuel estimator to cross-check.

What’s really going on

iRacing shows fuel in a few places: the cockpit/dashboard (some cars show liters, gallons, or %), the in-game pit-stop box (it can suggest fuel to add), and in replay/telemetry files for detailed analysis. There’s no single “fuel per lap” display by default, so the easiest reliable method is to measure a real change in the fuel number over known laps. Different cars and setups will change consumption, so measure in the same car/setup you plan to race.

Step-by-step fix

Start with a known fuel amount. Set a round number in the garage (for example, 20 liters/gallons) so your math is easy.
Verify the fuel readout is visible. Look at the cockpit dash and HUD; if nothing shows, enable cockpit gauges/HUD in the Display or Graphics options.
Run 5 clean laps at the pace you expect to use in the race. Avoid long lifts, heavy braking, or full-courses that will skew the result.
Note the fuel value after those laps. Subtract: (start fuel − end fuel) ÷ laps = fuel per lap. Example: 20.0 − 17.5 over 5 laps = 0.5 fuel per lap.
Use the pit-stop fuel estimator as a cross-check. It will show “fuel to add” for the remaining distance — use that to validate your measured per-lap number.
If you want more detail, enable telemetry export (or save the replay) and open the file in a telemetry viewer to see fuel used each lap.

Extra tips / checklist

If the dash shows percent instead of liters/gallons, use percentages the same way: start% − end% divided by laps.
Add a safety margin: +1–2 laps of fuel for incidents, safety cars, or fuel burn variation.
Fuel usage changes with aggressive throttle, higher boost (if applicable), and lower gearing; measure with your race setup, not a practice setup.
If the in-car readout jumps or shows unrealistic values, restart iRacing or switch camera views — HUD glitches are rare but possible.
For long stints, measure early and late in a stint; consumption can change as tires wear and fuel weight drops.

FAQs

Q: Why can’t I see any fuel number on my screen?
A: Your HUD or cockpit gauges may be off. Enable cockpit instruments or HUD elements in iRacing display settings, or try a different car view (cockpit vs. dash) to reveal the readout.

Q: Can iRacing show fuel used per lap automatically?
A: Not as a simple built-in readout. You’ll either calculate by hand (start − end ÷ laps) or use telemetry/replay tools for a lap-by-lap breakdown.

Q: How many laps should I test to get an accurate number?
A: 4–10 clean laps is enough. Fewer than 3 is noisy; more than 10 is better for averaging but slower to collect.

Q: Does fuel consumption change with settings?
A: Yes. Engine maps, gearing, and driving style change fuel burn. Measure with the setup and driving style you’ll use in the race.

Short wrap-up

Finding fuel usage in iRacing is simple: read the fuel display, run a short test, and divide fuel used by laps. Next session: measure once with your race setup, add a lap or two of margin, and you’ll stop guessing at pit time.
