Spotted $4.19 unleaded and $5.09 diesel at Sinclair in Missoula today. Montana is now $1.02 more per gallon than this time last year. We're ranked 10th most expensive state in the country. That's where we are 165 days into this war.

For context, we were at $2.78 the day it started.

Prices peaked in mid-May then fell seven weeks straight when diplomacy looked like it might go somewhere. The moment talks fell apart, prices shot back up. We're still $1.41 above where we started and there's no deal in sight.

Fill up a 15-gallon tank today and you're paying $21 more than you were on Feb 28. Got a diesel pickup with a 48-gallon tank? That's $78 more. Every time.

Cheapest station in Montana right now: $3.86. Most expensive: $5.34.

**We were under $3.00 before this war. Remember that.**

Gas is up 50% since the Iran War started. Here's every data point, because apparently we need receipts.
