Noticed recently that you can make impregnated sticks with creosote oil instead of seed oil. It seems odd because creosote is so abundant in large quantities if you make coal coke at all, but seed oil you only get 3mB per seed and it takes absolutely forever to get it in any sort of quantity. Plus the squeezer requires 250MJ per seed to squeeze it I think. Very costly to produce. Is there any reason to make seed oil if you can just use creosote to make your frames with?
