45,000 mile (72,000 km) update for my Sep 2021 SR+ LFP. The car is now 18 months old and was originally rated at 253 miles on a full charge. The Tessie app shows a battery capacity of 52.0 kWh (down 4.8% from my original 23 Oct 2021 post of 54.6 kWh), and a max range of 241 miles (down 4.8% from my original range of 253 miles). I've had Tessie since my first day or two or ownership, so this data shows the entire life of the car.

According to the car's screen, I'm averaging 212 Wh/mi over the life of the car (the same as it was at the 40,000 mile update)--we've barely had a winter here this year, so my average wh/mi has actually gone down over the last several months due to the warm weather. Seasonal temps and driving style are HUGE when it comes to the car's efficiency. In the winter I can expect 240+ Wh/mi when it's below 30f, and in ideal temps (75-85f) I routinely manage under 200 Wh/mi on my 100 mile round-trip commute. Assuming I could tap into the current 52.0 kWh battery at my lifetime average 212 Wh/mi efficiency, that gives me a real-world range of 245.3 miles.

My charging is mostly Level 2 from a Grizzl-E delivering 24 amps on a 40 amp circuit in my garage. I charge most nights due to a long commute, typically to about 70-80% a few times per week and a 100% once or twice a week. I do fast charge about once per week on average because I'm a beekeeper and I make honey deliveries across a few counties most weekends (going to do that after I post this, in fact)...I use both Superchargers and CCS chargers like Electrify America or Chargepoint, depending on which are more convenient at the time.
Tessie says I've spent $1,136.70 on electricity driving the car, while the same distance in my old Ford Focus would've cost $4,403.39 in gasoline. So my fuel costs have been 26% compared to keeping my old car. Assuming the average US emissions of 0.85 pounds CO2 per kWh, the 9,615 kWh used while driving equates to 8,173 pounds of CO2 spent driving my Tesla. If I'd kept my 2012 Ford Focus (37mpg), I would've used 1,224 gallons of gas to travel these 45,291 miles. At about 19 pounds of CO2 per gallon, that would've been 23,257 pounds of CO2. So I'm spewing 35% of the carbon emissions than I would've released in my efficient little Focus. As the grid moves toward more renewables, that should only get better over the life of the car.
AND ANOTHER THING...I'm currently in the process of having an 11.1 kw solar system installed. This array should provide enough energy to cover all of my electricity use over the course of the year, so once we flip the switch my Tesla will be a true zero emission vehicle.

I'll try to post another update at 50,000 miles.
