He he, ive had the light going on at around 30 something, it depends what my average mpg is as to when it comes on. If im doing a higher mpg and still driving easy towards the end of the tank then the light doesnt come on for a while and visa versa.
Saying that, when the light came on at 50 miles left, i managed another 100mies, obviously i wasnt kaining it, i think i might have been on the motorway... I tend to use the actual fuel gauge to determine the file thats left. When the needle gets to the lower half of the red line thats when i know i need to fill up within about 15 min worth of driving (few miles)
I managed 430 miles on one tank from Le-mans to my house! Which i was quietly impressed with considering in France my motorway speed was around 80mph.
