@BreakingNYC Part of the problem is the fuel igniting by the PRTO, so about an eighth to a quarter is burnt up uselessly. Despite have about 3 layers of liquid only wall and GOL coolers to stop heat ignition, it still ignites. :I
Well, even if it isn't fuel efficient, I'm still quite happy with it. :) The fuel ignition while it's in the tank is a TPT bug, as somehow FIRE manages to live for 3 frames inside liquid only wall... -_-
@cctvdude99 You should try adding one layer of PRTI and one layer of PRTO next to the E-wall that brings oil to the ignition chamber (in the ignition chamber's side).
