The P-47 in game currently doesn’t use or give the option for 150 Grade fuel. May of 1944 the 8th AF decided all P-38/47/51 groups receive 44-1 fuel immediately.
They did many tests at altitude and with ground attack variants and once they were pleased with the testing they pushed it out. The only thing I noticed was most P-38/47 Squads were converted to P-51’s so their time using the fuel was slightly limited.
I really enjoy flying the Jug but with its current power output it really leaves me wanting more. The 150 grade fuel gave the Jug over 3,000 Ft per min climb rate at 10,000 ft, compared to the 2,000 Ft per min it has now. I’m hoping it’s taken into consideration as it was historically used on the front. They even went to the lengths of filling the wing tanks with the lower 130 for the climb out, and filled the onboard with 150 specifically for combat use. The Jug desperately needs 150 fuel in my opinion I’m curious what the masses think.
