That's only possible if you pickup luftwaffe fuel supply drops.
How much fuel does UKF start with?
UKF:
30 + 115 - (x) = 145 in tech. (x) been initial fuel
100 for the Centaur / 110 for Cromwell
15/15/25 Upgrades (Nade/Rack/Bolster)
OH:
170f in tech (accounting for initial fuel)
100 for Ostwind / 125f PIV
SU:
170f in tech (accounting for initial fuel)
80f for T34
25/25 Upgrades (Molo/AT nade)
23f average for a 50/50 control map (4SP + 1fuel + Base). Should you add 1/2 cache, have a better presence on the map and you can put out a 10-12 min Centaur without problem.
Nade (which is a lackluster upgrade) should be fused with Bolster and Tank tier could be 10-25f more expensive (tech is gonna be -5f next patch)
