    Dodge 3.8 excessively bad gas millage

    Hey guys,
    Well after going to the cottage a couple times we have noticed even more horrible gas millage in our 2005 dodge grand caravan SXT. Has a newer engine put in, In December and since it has been just eating and drinking fuel like crazy! It's to the point that it was worse than our pick up truck. Last couple time up to our cottage it had used a tank and a bit of fuel ( only 202 km max to cottage) and we drive around 2000 RPM but again it just eats fuel like crazy. If anyone can chime in and maybe give a few pointers to figuring this out, it would be very helpfull.

    The original 3.8 was no where near as bad on gas than the one in there now ( just a side not) was thinking maybe oxygen sensors but then again no engine light is on

    What do you mean by background? And the other engine was changed because while driving it stared pissing out oil without us
    Noticing and it was too far gone when we towed it to the shop

    Nope engine that is currently in it had no issues other than horrible gas millage. Even worse than a jeep. But since the new engine has been in it has had regular oil changes with the correct oil ( 10W- 30)
