I think it’s also more efficient to burn the hydrocarbons in a large generator and using the power to charge an EV,
combustion engines on vehicles are limited in weight size and shape, and since its rpm varies a lot during driving it is not operating at peak efficiency
a large and heavy generator can extract more of the energy, and always runs at the optimal operating speed, making it way more efficient, producing enough additional to cover the conversion losses of the mechanical->electric->electrochemical->electric->mechanical chain and then some
Thats not whats happening in the real world though. You wouldnt need to refine oil into gasoline to burn that if you can simply use the currently available methods for generating electricity
Edit: after reading the comment you answered to again, it reads like they meant the same kind of efficiency you were talking about. Thats still not relevant for this scenario though.

The last time I looked the difference in efficiency isn’t large. Somewhere like 10%, but it does make a difference at scale.
That doesn’t track with what I’ve seen. I’ve seen a few sources mention much larger efficiency gains. E.g. From motor trend: https://www.motortrend.com/news/evs-more-efficient-than-internal-combustion-engines
I was talking about the efficiency difference between a generator and an internal combustion vehicle engine running on the same fuel.
