As part of my effort to closely track the cost savings of our Tesla, I wrote a program that uses Gas Buddy to track the prices of the six gas stations closest to our house with the logic being that these are the places we’d be most likely to buy gas from. In reality, we buy almost all our gas at Safeway but for some reason that one doesn’t usually have prices listed on Gas Buddy.
That program started running a year ago and below is the chart of how things have changed. The orange line (the cheapest gas) is usually the Costco near us.
When I was doing the calculations about whether I could save money with a Model Y versus buying another Ford Escape, I had planned on $3.50/gallon. So with the average gas price barely ever dipping below $4/gallon, I’m ahead of my estimated savings mark. But I’ll more on those specific savings numbers when we reach 20,000 miles in a few months.
