Jones Brothers Racing Practice Test

Fuel windows hinge on burn rate and laps left. The best method is to use the actual fuel you expect to burn per lap from practice data under similar conditions, multiply that by the number of laps remaining to finish at that pace, and then add a safety margin to cover variations in pace, tyre wear, traffic, and possible safety-car periods. As the race unfolds, monitor how your actual usage compares to the plan and adjust at each pit stop if pace or fuel burn is different than expected. This approach gives a realistic, flexible window and helps prevent both carrying too much fuel (which slows the car) and running out before the finish.

Relying on a fixed plan from practice ignores real-race variability, starting with a full tank and hoping it lasts wastes performance, ignoring laps remaining can lead to misjudging how much fuel you truly need, and only considering total race fuel without accounting for how many laps are left misses the timing needed to stay in the window.
