Fill-up accounting time:

Unfortunately with fuel prices nowadays, I actually was not able to fill the nearly empty tank all the way at a Valero with a 100 dollar transaction limit! I added 17.2 gallons there and the needle was at the full mark. However when I last filled up, the needle didn't actually reach the full mark (the fill port is finicky and does this a lot), so I want to say I likely burned under 17 gallons, but we'll call it 17.

I had to go look at the State Farm app logs to see how far I actually drove and the number shocked me: I made it 462 miles!

462/17=27mpg

There is a catch: There's a 5000 foot descent in there which is like 40 free miles (and I took advantage of it by rolling down the hill in neutral).

Still, 25mpg on flat land is not bad! I did a bit of cruise control on a longer trip to reduce fatigue but 100 miles of that tank were very diligent P&G.

The nice thing is I actually still have more mpg left on the table: My engine oil can go down one more grade, my engine coolant temp was never hot so I could've blocked the grill more, and I was on winter fuel. More "normal" driving would probably end up at around 20 which is still way better than the 13mpg average displayed on the screen when I got the car.
