Yeah that is mine too like I said several posts ago on here but nobody reads this ****? I think it must be a common SVX problem because you are describing my car you last two guys. However, the low fuel lights is always spot on and you have a good 2+ gallons left. Just need to figure your mileage per tank and reset at every fill up. That combined with the light and you will never have to worry bout the gage. I here it is because of the saddle tank system on the SVX with the rear seats is why.
