rizkipatra Posted July 12, 2012 Report Share Posted July 12, 2012 Hi all, anybody know how to improve fuel consumption in Lumina 2003 3800cc V6? I find it now very thirsty. 50dhs (about 30 liters)for 85km only, in town traffic. that's within 2 days, with AC on number 2 or 3 in daytime, and 1 in night time. That's even thirstier than a 4800cc V8 SUV. I hardly use the power of its 3.8 liter engine. very seldom quick acceleration and no hard braking..

unclesam Posted July 15, 2012 Report Share Posted July 15, 2012 check the fuel gauge if it working. see if the fuel is getting leaked somewhere else. when was the car last serviced? Link to comment Share on other sites More sharing options...
rizkipatra Posted July 20, 2012 Author Report Share Posted July 20, 2012 unclesam, fuel gauge is fine.. i leave my Lumi in garage for major check up and will get the reports tomorrow. i'm suspecting the o2 sensor after reading many articles about fuel consumption. Thanks for your advise, though! Link to comment Share on other sites More sharing options...
