Some of the fuel gauges are very accurate but some aren’t. I’ve repaired some dual sending element systems that were a real pain to diagnose. But this is a new Buick and you’d think that the dealer would satisfy an owner on the situation. I mean did the dealer verify the bar code on the tank was for 16 gallons? If necessary they could pump the tank empty and fill it while watching the gauge. Of course I’m out here in never never land unable to see the gauge operate and fill the tank and I have never depended on a fuel gauge to determine when to fill up. I estimate the average expected miles from full to empty and multiply X .80 and round it off to an even number and reset my trip meter at every fill up. And FWIW most every domestic vehicle that I have owned has been slow to show fuel drop in the first half of the tank full and quick in the second half. My old Blazer seems to drop from 1/4 to E in less than 10 miles while from F to 3/4 will accumulate 80 +/- miles.
