Can't find it now, but you are probably right for newer and well maintained ICE engines. I'm guessing that the 1.5X-3X range I saw includes old and badly maintained engines. They could also have been measuring overall fuel to wheel efficiency and including a ~15% loss in the transmission and drive train and maybe also including average time spent idling (which doesn't apply to EVs).
Keep in mind that there are a lot of shitty cars on the road. A power plant's engine is going to usually be well tuned and maintained because small increases in efficiency can be worth a ton of money when you are generating tens of gigawatt hours per day of power. How often does a typical driver of a middle-aged car take it in to be tuned with the objective of maximizing energy efficiency?
I bet the average gap across all cars on the road and including transmission loss is at least 2X.
Also it's tough to argue against the second point. Look into how much power is used in the oil to gasoline supply chain, especially if the oil is coming from heavy oil that requires an additional cracking ("upgrading") step or fracked wells that require a lot of energy to drill and hydraulically fracture. I recall reading an analysis years ago arguing that the Canadian tar sands are almost an indirect natural gas to oil conversion operation rather than a net producer of energy. A huge amount of gas is burned to get that stuff out of the ground and into a form that refineries can handle. You could instead just burn that gas in a combined cycle power plant and run EVs with it and emit a lot less carbon.
Thing is when you are buying any oil product you are really not buying energy. It's ridiculously expensive compared to energy from any other source. You are buying conveniently stored energy and paying a huge markup for it.
