LPG in the BBQs usually 3 * 8.5kg before I have to use the butane stove and about 10 litres of 50/50 kero/Shellite fuel for the MSR [ bought a bulk load at BCF clearance a while back] Having cooked in some out of the way places over 30 years I got used to always having a minimum of a weeks supply in the stores.
