There are pros and cons with propane as a generator fuel. In general, propane is less efficient than gasoline, so you use more and get less out of it. On the upside, propane produces fewer harmful emissions than gas, and doesn’t get “stale”. Most home stand-by generators are either propane or natural gas depending on what’s available, party for convenience, party for reliability.

In the end it comes down to personal choice which is easier or more convenient to carry, or purchase or is more cost effective. Having a choice with a dual-fuel unit is attractive as long as the cost difference is worth it.
