Managing Fuel Consumption During Long Green-Flag Runs

Learn managing fuel consumption during long green-flag runs in NASCAR 25: easy habits, menu tweaks, and driving tricks to stretch your tank without losing pace.


Updated August 15, 2025

Long green-flag runs can wreck your race if you pit one lap earlier than everyone else. You fall off the lead lap, lose track position, and feel like the AI is “cheating” on fuel. This guide walks you through managing fuel consumption during long green-flag runs so you can match or beat the strategy of the field.

Quick answer

To save fuel in NASCAR 25, you have two main tools: how you drive (throttle, braking, and drafting) and how your car is set up (fuel mix if available, gear ratios, and assists). You want smooth inputs, earlier lifting into the corner, and smart use of the draft on straights.

If the game lets you adjust fuel maps or engine modes, run a leaner setting during long runs when you’re not fighting hard for position. Combine that with consistent lap times (not sliding the car) and you can often gain 2–4 laps of range on an oval without feeling slow.

Do this now (60 seconds)

  • Pick any oval in Practice or Test mode so you can run laps without race pressure.
  • Turn on your HUD elements that show “Fuel laps remaining” or “Fuel use per lap” (look for a telemetry, HUD, or driving info toggle).
  • Run 3 laps at normal pace and note average fuel use per lap.
  • Now run 3 laps where you: lift off throttle earlier, brake less, and stay in another car’s draft when possible.
  • Compare laps-remaining before/after; if you gained at least 0.1–0.2 laps per lap, you’re on the right track.

What this means in NASCAR 25

When we talk about “managing fuel consumption during long green-flag runs” we’re talking about stretching how many laps you can go before pitting, without losing too much speed.

On long green-flag runs:

  • Fuel management decides if you can pit with the leaders or if you need an extra stop.
  • Track position: One extra pit stop can cost you 30+ seconds, which is often a full lap on many ovals.
  • Tire/fuel balance: Sometimes your tires are still “okay” but you’re out of fuel; other times you have fuel but your tires are dead. You’re trying to sync those up.
  • Strategy windows: A “fuel window” is the range of laps where you must pit. If you can extend that window even 2–3 laps, you get more options if a caution comes out.

Quick jargon:

  • Draft: The aerodynamic pull behind another car. You get less air resistance, so you can use less throttle to go the same speed.
  • Lift early: Coming off the gas pedal sooner before the corner instead of driving in hard and braking late.
  • Rolling the corner: Letting the car carry speed through the turn with minimal braking and smooth throttle.
  • Fuel map/engine mix (if the game includes this): A setting that trades power for better fuel mileage.

Use this like a quick troubleshooting map.

Common fuel problems and how to fix them

  • Symptom: You always have to pit 3–5 laps earlier than the AI.

    • Likely cause: Overdriving – too much throttle on exit, heavy braking, not using draft.
    • Fix: Lift earlier, brake less, and let the car coast a bit before turn-in. Stick behind a car on straights instead of running alone or side-by-side.
  • Symptom: You run fast laps but your right-front tire and fuel are gone way sooner than expected.

    • Likely cause: Driving too hard into corners, causing sliding and tire spin on exit.
    • Fix: Enter corners a bit slower, focus on clean exits. You should feel less sliding and wheelspin; your lap times might drop a tenth or two but fuel and tire life improve.
  • Symptom: You save fuel early, but then panic-race and lose all the benefit near the end of the run.

    • Likely cause: Inconsistent driving rhythm; you switch styles too often.
    • Fix: Commit to one approach: decide “Save fuel this run” and drive smooth the entire run. Don’t suddenly start overdriving with 10 laps to go in the stint.
  • Symptom: You change setups but don’t see any difference in fuel usage.

    • Likely cause: Changes too small to notice or fuel map/assists overriding minor setup tweaks.
    • Fix: Focus on driving habits first, then try larger, deliberate changes (like noticeably taller gearing if available) and re-test fuel use over at least 5–10 laps.
  • Symptom: You pit with everyone, but still run out of fuel 1–2 laps before the stop window next run.

    • Likely cause: Not filling the car all the way or running higher fuel mix when racing hard.
    • Fix: Double-check pit strategy screen to ensure “full tank” is selected. If fuel maps exist, don’t sit on max power the entire stint.

Step-by-step: How to do it

This section assumes a typical NASCAR-style racing game UI. NASCAR 25 may label menus differently, so use these as patterns and look for similar wording.

1. Turn on fuel info in your HUD

  1. From the main menu, go to something like Options, Settings, or Gameplay.
  2. Look for sub-menus like HUD, On-Screen Display (OSD), or Driving Information.
  3. Enable anything that sounds like:
    • “Fuel Remaining”
    • “Laps of Fuel Left”
    • “Telemetry” or “Car Status”
  4. Start a Practice, Single Race, or Test Session and confirm that you can see how many laps of fuel you have.

You’ll know it’s working when the HUD shows either a fuel bar with lap count or a numeric “laps remaining” value that drops steadily each lap.

Common gotcha: Some games hide advanced HUD elements by default in higher difficulty modes. If you don’t see fuel info, try lowering HUD realism or switching to a more detailed in-car display with a button (look for a “cycle display” or “change dash” control in the control settings).

2. Establish your “baseline” fuel use

  1. Go to an oval track (any 1.0–1.5-mile speedway is great for learning).
  2. Load a Practice or Solo Session with a full tank of fuel.
  3. Run 5 consecutive laps driving how you normally would in a race.
  4. On lap 2–5, each time you cross the line, note:
    • Laps of fuel remaining
    • Your approximate lap time

Example:

  • Lap 2: 41.3 seconds, 39.1 laps of fuel left
  • Lap 5: 41.4 seconds, 36.0 laps of fuel left

You now know your normal fuel burn rate.

3. Try the “lift early and roll” technique

  1. Coming into Turn 1 and Turn 3, lift off the throttle earlier than usual. For example, lift at the start of the turn entry markers instead of halfway down.
  2. Use less brake. Ideally, you’re rolling the car into the corner with a short, light stab of brake or no brake at all on some tracks.
  3. Don’t slam back on the gas at corner exit; squeeze the throttle on gradually to avoid wheelspin.
  4. Repeat 5 laps like this and compare fuel laps remaining at the end vs your baseline.

You should feel the car more stable and less “shocked” into the corner. If your lap times are within 0.1–0.3 seconds of your baseline but you gained even 1 lap over a 20-lap run, that’s a big win.

Common gotcha: If you back off too much, you’ll lose the draft and slow down a lot. The goal isn’t “slow,” it’s “smooth and efficient.”

4. Use the draft to save fuel

  1. In a race or with AI cars in practice, settle in behind a car that’s roughly your pace.
  2. On the straights, move slightly lower or directly in line behind them to feel the pull of the draft.
  3. While drafting, try running slightly less throttle (for example 90–95% instead of 100%) but stay glued to their bumper gap.
  4. Watch your speedometer or lap times; if speed stays up while your throttle is lower, you’re saving fuel.

You’ll know it’s working when you can hold the same speed with less throttle and see a slower drop in “laps of fuel remaining” compared to running alone.

Common gotcha: Don’t keep poking out of line to pass if you’re saving fuel; every move into clean air costs you efficiency. Commit to either “push now” or “save now.”

5. (If available) Adjust fuel map/engine mode

If NASCAR 25 includes in-race engine modes or fuel maps:

  1. Check the Controls or Settings menu for something like “Engine Map Up/Down,” “Fuel Mix,” or “ERS/Engine Mode.”
  2. During a long green run where you’re not attacking, switch to a “lean” or “fuel save” mode. It may be labeled:
    • “Lean / Normal / Rich”
    • “Fuel Save / Standard / Power”
  3. Expect slightly less acceleration but better fuel usage. Use this when riding in a pack or in the middle of a long stint.

You’ll know it’s working when your “laps of fuel remaining” drops more slowly lap-to-lap, even if your lap times are a tick slower.

Common gotcha: Don’t stay in lean mode during restarts or when defending hard; you’ll get swallowed. Switch back to normal/rich for short, critical fights.


Fuel saving is easier to learn when the car is predictable.

  • Beginner

    • Keep stability/traction assists ON so the car doesn’t slide much. Sliding kills tires and fuel.
    • Use a medium AI difficulty so you can sit in the draft without getting dropped or running them over.
    • Turn full HUD info ON, especially fuel and tire wear.
  • Intermediate

    • Gradually reduce stability/traction help so you can feel when you’re overdriving the corner.
    • Consider more realistic tire wear and fuel usage (if there’s a slider).
    • Focus on making your own pace while still using draft to save fuel.
  • Advanced

    • Minimal or no assists; full fuel and tire wear enabled.
    • If gearbox options exist, consider slightly taller final drive to reduce RPM on straights, then test if it doesn’t kill exit speed.
    • Practice running alternate strategies: one stint “push,” next stint “save,” and compare results.

Practice drill (10 minutes)

Goal: Feel how much you can save without losing the pack.

  • Track: Any 1.0–1.5-mile oval with moderate banking (typical speedway).
  • Session type: 25–40 lap race against AI, full fuel and tire wear.

Drill steps

  1. Stint 1 (push mode):

    • First 10 laps, drive naturally, no fuel saving. Stay aggressive but clean.
    • Note laps of fuel remaining at lap 10.
  2. Stint 2 (save mode):

    • Next 10 laps, focus on: lifting earlier, rolling the center, drafting on straights, and smooth throttle.
    • Stay in the draft of the pack; don’t let big gaps open.
    • Note laps of fuel remaining at lap 20.
  3. Compare: If you have at least 1–2 more laps in the tank at lap 20 during save mode vs push mode while still running with the group, you’re doing it right.

What success looks like: Your average lap time only drops a few tenths, but your fuel window stretches by multiple laps.

Mistake to avoid: Don’t run this drill side-by-side racing every corner. You’re practicing patience, not overtakes.


Common beginner mistakes (and the fix)

  1. Flat-out every lap, every corner

    • Looks like: You’re on full throttle whenever you’re not hard on the brake.
    • Why it happens: You think “faster inputs = faster lap.”
    • Fix: Start lifting off throttle before the corner entry marker and aim to brake less. Let the car coast a moment before turn-in.
  2. Ignoring fuel until the low-fuel warning

    • Looks like: You only think about fuel when the game flashes a warning.
    • Why it happens: You’re focused only on passing cars, not race distance.
    • Fix: Check your “laps of fuel remaining” every 3–5 laps and mentally compare it to laps left in the stage/race.
  3. Racing side-by-side when you’re supposed to be saving

    • Looks like: Constantly running in dirty air, no draft benefit, burning extra fuel.
    • Why it happens: It’s fun to race, and no one wants to give up a spot.
    • Fix: Choose a car to tuck in behind and ride for a while. Tell yourself “save now, attack later.”
  4. Over-braking into corners

    • Looks like: Car slows too much, then you hammer the gas to get back up to speed.
    • Why it happens: Fear of missing the corner or hitting the wall.
    • Fix: Lift earlier and use lighter, shorter brake pressure. If you’re below the white line and still slowing, you braked too much.
  5. Wheelspin on exit

    • Looks like: Back end wiggles, revs jump up, car slides to the wall.
    • Why it happens: Too much throttle too early.
    • Fix: Wait until the car is pointed more down the straight, then feed in throttle smoothly instead of instantly going 100%.
  6. Staying in clean air on straights when you could draft

    • Looks like: Running your own lone line in the middle of the track.
    • Why it happens: Habit from time trial/hot lap modes.
    • Fix: Practice running 1–2 car lengths behind another car on the straights. Use the draft as a “free engine upgrade.”
  7. Changing too many settings at once

    • Looks like: You adjust setup, assists, difficulty, and style all at the same time and don’t know what helped.
    • Why it happens: Eager to fix everything immediately.
    • Fix: Change one thing at a time (e.g., try lift-early-only for one run) and see how it affects fuel before stacking more changes.

FAQs

How do I save fuel without being way slower in NASCAR 25?
Focus on being smoother, not just slower. Lift earlier into corners, roll more speed through the middle, and use the draft on straights. If your lap times only drop by a couple tenths but you gain 2–4 laps of range over a run, that’s successful fuel saving.

Is lifting early really better than braking later for fuel saving?
Yes. Lifting early lets the car decelerate without dumping extra fuel or overworking the brakes and tires. Late, hard braking usually leads to over-slowing then mashing the throttle to recover, which burns more fuel and overheats the tires.

How many laps can I gain by managing fuel consumption during long green-flag runs?
It depends on the track and game model, but in most NASCAR-style titles you can expect 1–4 extra laps over a full tank if you commit to fuel saving: smooth inputs, drafting, and possibly a leaner engine map if available. Even 1–2 laps can completely change your pit strategy.

Should I always save fuel in NASCAR 25?
No. Fuel saving is a tool, not a default mode. Use it when: you’re safely in a pack, early/mid-stint on a long green run, or trying to make a pit window or stage end. On restarts, defending, or going for a late-race move, it’s usually better to push.

Does drafting really help fuel in the game, or is it just for speed?
In most modern NASCAR games, drafting helps both. You need less throttle to hold the same speed when tucked in behind another car, which means less fuel burned per lap. If your HUD shows throttle input and fuel, you can watch this effect happening in real time.

What’s more important for beginners: tire saving or fuel saving?
They’re closely linked. Overdriving burns both tires and fuel. For a beginner, focus on clean, smooth cornering that keeps the car from sliding; you’ll usually see both tire life and fuel range improve together.


Next steps

Fuel management is about rhythm and discipline, not secret tricks. If you can stay smooth, use the draft smartly, and watch your fuel numbers during the run, you’ll quickly stop being the driver who pits one lap too early.

Next time you race in NASCAR 25, pick one stint to be your “fuel run” and apply the lift-early, draft-heavy approach. Compare that stint to your normal style and adjust from there.
