I took my Trailblazer LT with the 1.3 and CVT on my trip to the Key West. 305 miles each way with about 60% at interstate speeds and th rest at 45-55 on US1. On the Interstate at 73-75, I saw right at 31-32mpg. On US1 doing the 45-55 crawl, I saw an average of 43-44mpg! Overall for the trip, I saw 34 going down and 37 coming back.
