Where These Numbers Come From
This page was built by Cedrick Reese from the U.S. EPA fuel economy dataset on fueleconomy.gov, which holds 204 ratings for the Chevrolet Suburban from 1984 to 2027. Each row in the table links to the matching EPA vehicle record, so you can check any figure against the source. Ratings from before 2008 use the EPA's revised estimates, which put older vehicles on the same scale as newer ones. The page is rebuilt whenever the EPA publishes an updated file, which picks up new model years and any rating corrections. The cost calculator uses the gas price you enter rather than a national average, so the result fits where you live.
Ratings on this page come from the EPA file downloaded on October 1, 2026.
