Typically I carry the saw full of fuel/bar oil and another 2 full Primus 1L fuel bottles, 1 premix and 1 bar oil. I haven't yet run out of fuel/oil on a trip, however if it is an early in the year trip after tracks are open, I'll carry spare unmixed fuel and 2-stroke blend just in case. As for other bits, tools for the saw, hand file/guide, stump vice, PPE, spare chain and bar, hard bristle brush, rag. The saw will leak bar oil so put a towel down in the case before you put the saw in.
