Diesel Fuel in Des Plaines is currently priced at approximately $$4.90 per gallon. Nearby cities have comparable prices within 10-15 cents depending on their state's tax structure and local competition.
Diesel Fuel costs more due to the additional refining required to achieve its specifications. Higher octane fuel requires more complex blending processes. The markup reflects real production costs, not arbitrary station pricing.
Check your vehicle's owner manual or the inside of your fuel door. Required means you must use that grade to avoid damage. Recommended means optimal performance uses that grade but lower grades are tolerable. Regular means 87 octane is sufficient.
For vehicles designed to use Diesel Fuel, using the correct grade maintains engineered fuel economy. Upgrading from regular to premium in a regular-fuel car produces no economy improvement. Using regular in a premium-required car may reduce fuel economy slightly.
