Tips for Getting Better Gas Prices in Iowa
- Compare station prices in Des Moines or Cedar Rapids before heading onto rural stretches of I-80 or I-35.
- Fill up your tank before driving through remote agricultural areas in western or northern Iowa.
- Check your tire pressure regularly, especially during extreme Midwest winter cold and summer heat.
- Stick to regular unleaded (or E15 if your vehicle supports it) unless your manufacturer explicitly requires premium.

- Avoid unnecessary idling in heavy metro traffic or at travel plazas along the interstate.
Iowa Gas Price FAQs
What is the average gas price in Iowa today?
The current daily averages for regular, mid-grade, premium, and diesel are displayed in the dynamic tool at the top of this page.
Why do Des Moines and Sioux City gas prices differ?
Des Moines relies heavily on regional pipeline supply and massive metro commuter demand, while Sioux City is influenced by different local distribution networks and cross-border market dynamics with Nebraska and South Dakota.
Does Iowa use special gasoline blends?
Iowa is a major producer of ethanol, so standard regular unleaded is typically blended with 10% ethanol (E10). Many stations also offer E15, which can sometimes be cheaper than standard E10 depending on local incentives and seasonal rules.
Is diesel included in Iowa gas price data?
Yes, the tool tracks Iowa diesel prices alongside unleaded options, which is essential for commercial truckers, agricultural transport, and RV travelers navigating the state’s major freight corridors.
Why can rural areas in Iowa cost more at the pump?
Stations in remote farming towns face less local competition and higher overhead costs for fuel delivery over longer distances from major Midwest distribution hubs.
