SpaceX orbital launch table saves some launch mass by providing nitrogen, hot oxygen and hot methane to ignite the engines. I think connecting the outer engines to the fuel supplied for ignition will save a few tons from the booster.
SpaceX will hopefully launch the Super Heavy Starship to orbit in the next month or two.
