Not that it would even the score probably but I‘ve noticed many if not all of these comparisons use premium fuel costs as the basis for comparison. While I know there are cars out there that require premium and some people believe it is better for their cars that don’t require it, I’ve never owned a car or truck that required premium gas. This seems like a ploy to make the savings more than they really are.The tech shows the real time energy use and costs based on my power source. Savings compared to avg gas price at the time of charge.
