All of this pales next to the following fact: all fuel-fired cars use more electricity than all current EVs, due to the average 8 kWh used to refine a gallon of gasoline.

Now who is propagating myths?
Just because Elon says it, doesn't mean it's true. That figure is based on the energy efficiency for refining gasoline from crude oil.... Here is one source for the electricity figure:
Electric Mini: It takes a lot of coal to make gasoline
But... most of that energy does not come from electricity.
If you check out HIS source, it's this study which shows energy efficiencies for petroleum refineries:

It also shows where the energy comes from that the refineries use. See pg 8.
Purchased electricity makes up a small percentage of the energy consumed, just 4.3%. Plus there is some electricity generated at the refinery (cogeneration) that wouldn't be generated at all if the refinery wasn't using it. The bulk of the energy used is from burning fuels (primarily products from the crude oil) in furnaces and boilers. So, how much actual electricity is actually used to make a gallon of gas? A fraction of a kWh.
