Re: Looking into buying a 05 or 06 Trailblazer
I have an 02 with the 4.2L I6, I get about sticker on mileage. From what Ive heard, the 5.3L V8 with DOD gets right about the same mileage, but isnt as smooth as the inline 6, but has ~60ft lbs tq and 39 more hp than the I6. The SS 6.0L V8 gets about 2-3 mpg less than the other two engines. If I were to get another TB (besides an SS) I would have to think long and hard about which engine I got, as I tow a fair amount, but it is a difficult decision.
BTW, the TQ and HP differences Ive guoted are for 06 TBs only, as GM upped the HP for 06 by 16hp.
