(FAQ)
Rocky Mountain diesel questions
Source: U.S. Energy Information Administration, weekly No. 2 diesel retail prices (PADD 4).
01Which states are in the Rocky Mountain diesel price region?
The EIA's PADD 4 region covers Colorado, Idaho, Montana, Utah and Wyoming. Prices are a weekly average across retail stations in the region, so local prices can be higher or lower.
02Should my fuel surcharge use the regional or national price?
Use whichever best matches what you actually pay. A regional index tracks local prices more closely; the U.S. average is simpler and more familiar to customers. Pick one, name it in your notice or contract, and stick with it.
03How often is this price updated?
The EIA publishes retail diesel prices weekly, usually on Monday afternoons. This page refreshes automatically.
04How do I turn the diesel price into a surcharge?
Multiply the increase per gallon (today's price minus the price your rates were set at) by gallons used per month, then divide by jobs per month. The calculator does it for you.
