How big is the fuel tank?

...on a Trailblazer? Looking to buy one, but if it has a small tank like my 2001 GMC Jimmy had I am not gonna buy. Had to refill every 300km / 190 miles (with a safety).

How many liters/gallons fit in there and for how long approx. does a tank last (HWY use)?

18.7 gallons for the 2002 and 2003 I6.



YMMV.

2004 Envoy XUV 25 gal tank (94.63 liters), I get about 230 miles (370km) but that was pulling a 3000lb (1360kg) pop-up

So after 2002 it went up from 18.5 Gal to 22? For all non-ext Trailblazers?

Yes but your truck will fillup base on your pcm/ecm. So if your truck orginally came with an 18 gal but you install a 22 gal you will fillup to 18 gals only.

How's that work? Do you mean the DIC will still be calibrated to an 18 gal tank or am I missing something?
