Idaho against the US average
Every point is an EIA survey week. This season Idaho ran from a low of $2.51 (5 Oct) to a high of $2.69 (26 Oct), with the US average finishing at $2.73. Against the same week a year earlier it is +16%.

What a fill costs in Idaho at $2.69
Tanks fill to 80% of their stated size to leave room for expansion, so a 500-gallon tank takes about 400 gallons. The right-hand column is the difference against the same fill at the US average.
| Tank | Usable gallons | Fill at $2.69 | vs US ($2.73) |
|---|---|---|---|
| 100 gal | 80 gal | $215 | -$4 |
| 250 gal | 200 gal | $537 | -$9 |
| 500 gal | 400 gal | $1074 | -$18 |
| 1000 gal | 800 gal | $2149 | -$35 |
For a winter's fuel, multiply the gallons on last winter's delivery tickets by the price: every 100 gallons costs about $269 at this price, before tank rent or a service plan. The average is a benchmark, not a quote: enter your ZIP to ask up to three local dealers what they would charge you.
