Racing Fuel & Stint Calculator
Stop guessing fuel loads. Enter your track data to get precise fuel requirements and pit stop strategies for endurance races or track days.
Race Parameters
Fuel Strategy
Includes 1 safety lap(s).
Fuel Use Variability
Fuel consumption changes with throttle application, engine tuning, ambient temperature, and track elevation. Always carry reserve fuel.
- Fuel consumption can vary ±20% from calculations
- Cold engines use more fuel
- Include a 1–2 lap safety margin
Methodology
Fuel Required: (Total Laps + Buffer) × Fuel per Lap
Buffer Laps: Safety margin for pace variation and contingencies
Frequently Asked Questions
How accurate is fuel consumption at race pace?
This calculator estimates based on power output and duration. Real-world varies by driving style, fuel type, engine efficiency, and weather. Use as a starting point, then adjust based on practice.
Should I add extra fuel as a safety margin?
Yes, 5-10% contingency is standard. Conservative est: 60L for 2 hours → add 3-6L buffer. Running out of fuel mid-race is worse than slightly wasted fuel.
Does fuel type (pump vs. race fuel) affect consumption?
Yes. Higher octane fuel allows more aggressive timing, potentially increasing power (better efficiency for same distance). However, fuel economy may still vary.
