Idaho's E85 landscape is sparse, with just 3 public stations across the entire state—all operated by Stinker Stores under the Sinclair brand. For flex fuel drivers, this western mountain state requires careful planning.
Idaho's agricultural economy centers on potatoes, dairy, and wheat—not corn. This fundamental difference from Midwest corn-belt states means no local ethanol production incentive exists. The state's 1.9 million residents spread across 83,000 square miles create low demand density.
Idaho does have one ethanol plant: Pacific Ethanol's Magic Valley facility in Burley produces 60 million gallons annually, but this supply feeds broader regional markets rather than building local retail infrastructure.
Idaho provides minimal E85 incentives. No renewable fuel standard exists, and infrastructure programs for E85 are essentially absent.
All three stations cluster in accessible but limited locations: Boise (2323 Main Street), Nampa (3319 Garrity Boulevard), and Lewiston (124 Thain Road). Two stations serve the Treasure Valley while Lewiston sits 300 miles north.
Eastern Idaho—including Idaho Falls, Pocatello, and Twin Falls—has zero E85 access. No stations exist along I-15 or I-86 corridors.
Treasure Valley residents can realistically incorporate E85 into their routine. For everyone else, treat E85 as a bonus when traveling through these areas. Neighboring state options offer limited help: Washington has roughly 7 stations, Oregon about 3, and Utah offers better coverage along the Wasatch Front.
