I've heard that and I think it's not fair to account for oil for calories that cyclists consume and not oil for calories that motorists burn, eg. a motorist who goes to the gym to workout instead of commute. One would have to account for the oil for calories "above and beyond" what the average motorist burns in the course of their day. No one calculates mpg that way.
