As well as FP1 rookie sessions, the Australian is undertaking 10 days of private F1 testing in older cars throughout the season, while also doing extensive simulator work at the factory, where the facilities are being upgraded this year.
Should either Esteban Ocon or Pierre Gasly move elsewhere as the silly season ramps up, Doohan will be well placed to take their seat, while also potentially being attractive to other teams should there be no vacancy in the Enstone camp.
"Outside of the current F1 grid for a driver who hasn't driven a race in F1 I'm definitely the driver with the highest mileage in the machinery," he told Autosport.
"And that's not over one lap, that's race distances, in the wet, in the dry, high temps, low temps. So I'm starting to see it all, which is really good and for sure only appealing to F1 teams.
"For me, the sole focus at the moment is trying to secure my place on the grid for next year, while also making sure I'm doing the job in these tests because they're very important as well."
His priority is to convince Alpine team boss Bruno Famin that he is the right man to replace Ocon or Gasly, should either of the current drivers depart.
"I'm absolutely determined," he said of his desire to be on the 2025 grid. "That's the plan, and that's also the plan with myself, Bruno and the team.
