4 solid fuel blocks(48MJ) required 40 fuel oil(40MJ+8MJ from coke), while 1 enriched fuel block(50MJ) required 100 liquid fuel(100MJ), or 80 fuel oil +20 residual gas. I think, we must align enriched fuel recipe with solid fuel recipe, like in pure angel&bob pack.
Enriched fuel is good for train fuel. They don't burn a lot so the efficiency loss doesn't matter much but the acceleration and top speed bonus is nice.
