Chevrolet TrailBlazer Gas Mileage

by

The Chevrolet TrailBlazer is one of America’s most popular SUVs. Introduced on its own platform in 2002, the TrailBlazer can be equipped with either a 291 horsepower inline six-cylinder or a pair of V-8 engines. Gas mileage, unfortunately, has never been one of the TrailBlazer’s strongest selling points. The TrailBlazer’s highway gas mileage ratings have floated around the 20 miles per gallon (MPG) mark, over the years.

The TrailBlazer SS, pictured above, is not your typical soccer mom’s SUV. The 6.0 liter LS2 Corvette V-8 engine in the TrailBlazer SS produces 395 horsepower (on premium unleaded), propelling the SUV from 0-60 in under six seconds.

Note: the EPA tweaked their testing procedure, starting with the 2008 model year, with the end result being that the 2008 MPG estimates are now lower than previous years. As always, YMMV.

1 thought on “Chevrolet TrailBlazer Gas Mileage”

  1. I have this car, a 2002 Trailblazer LS, and I average around 17-19 MPG. I do mostly highway driving so I get the best mileage possible. I also keep the engine below 2,500-3,000 rpm whenever I come out of stop signs or traffic lights. Also, using the cruise control on all the streets I drive through helps. I do the most I can to get the best mileage from this car despite the low ratings it has. It’s still an amazing car though!
