From a random forum[1]:
>Northern Air Cargo and Everets Air Freight (DC-3's, DC-4's, DC-6's etc.etc.) in Alaska burn two thirds of the 100LL produced in the United States.
... where 100LL is leaded gasoline. It is more or less the same here in Canada where almost all bush aviation runs on leaded gasoline. The remote communities served by such historical aircraft simply can not afford to do an instant upgrade of the fleet they depend on. They can't afford to do any upgrade really. It is well past time to start addressing the actual issues here.

- jacquesm 5y agoPretty tricky to do a technical fix for this, the problem is that the valve seats are not going to survive conversion to unleaded and re-manufacturing the individual heads or making inserts is going to be prohibitively expensive for those parties that still rely on the DC-3, which typically are not amongst the wealthiest entities. I wouldn't be surprised if enforcing this would cause more deaths than you'd ever save by using leaded gasoline for those planes. They're quite literally the lifeline for plenty of places.
