On-Highway Diesel Fuel Price Survey Methodology Change Notice

Originally Released: April 19, 2022
Updated: June 13, 2022

We are implementing new methodology to estimate weekly on-highway diesel fuel prices

On June 13, we started conducting the On-Highway Diesel Fuel Price Survey using new statistical methodologies. The published geographical areas for retail diesel fuel prices remain the same. As a result of the new statistical methodologies, the official, published price estimates for June 6 and June 13 are not directly comparable, so the weekly changes will not be published on June 13. Updated technical documentation on the new statistical methodologies includes a link to an Excel file that compares price estimates computed from the new sample for May 30 and June 6 with the official, published price estimates from the prior sample. If you have any questions, please see FAQs or contact our team.
