Well now that ive had my G6ET back for a few days and have knocked up over 600kms on the new engine, ive been keen to monitor the above ambient temp and fuel sender issues.... Well it seems mine are abit dodgy too. My fuel light comes on and the car beeped "80Kms" but when I filled it up it only took just over 51litres!, the outside temp degrees is out by around 8 degrees C, it seems to be especially bad on the cold mornings we have had here in the adelaide hills the past few days (temp says 14degrees C but outside its damn cold/foggy and around 6degrees C).
