NEVER Plan a Week-Long Outage on One Propane Cylinder (Generator Technician Explains)

Every generator buyer hears "get dual fuel, propane never goes bad" - and most of them cannot tell you what the second fuel actually costs. The wattage penalty is printed right on the spec plate nobody reads, and the box-store advice around it is wrong in both directions. Dual fuel is not a gimmick, and it is not free power. This episode walks the real arithmetic - why propane runs roughly ten percent lower, what a twenty-pound cylinder genuinely buys you in hours, why a hard freeze can starve a small bottle, and when the fuel that never degrades is worth the premium. In this video: 1.What the second fuel path actually is on a dual-fuel machine 2.The ten-percent propane derate, printed on real spec plates 3.When the penalty matters for your load list and when it is a rounding error 4.What propane does better - clean burning and no stale-fuel carburetor 5.Real cylinder runtime, the cold-weather catch, and the shelf-life trade 6.The cost-per-hour math nobody runs 7.The mistakes I would refuse, and the five checks before you buy What is your outage actually planned around - the gasoline number, or the fuel you really stored?
