I have an LT2 with the 3.6 and FWD and it is far beyond what I had expected and that was a lot. Previously I had a 1994 S10 and a 1998 back in the day, both 4.3s with 4WD when I livied in upsate NY. Now that I'm in FL, FWD is all I need. I recently took a 4000 mile month long trip to NY from FL and averaged 27.3 mpg. That's calculated, not per the computer. That registered about 1 mpg higher. On the interstates averaging 75 mph, I consistently got 28-29 mpg with the vehicle loaded. Locally, putzing around 1-6 miles at a time I average about 22-24. The thing goes like stink (I also drive a C6 Corvette Grand Sport) rides and handles great and is super quiet. Before the new Blazer I had 2 Equinoxes (2010 & 2016), which we really liked, but the Blazer is in another whole league. Did I mention that with tax, title, fees and all the B.S. I got out the door for under $30K. MSRP was $36,340.
