Fuel range LOW, only took 15 gal on 17.5 tank?
The fuel range warnings seemed to match other GM cars on my 2016 Prem ll. Fuel warning pops up in the 40 miles to empty range and once below 40 just says LOW. But when I filled up it only took 15+ gallons on a 17.5 gallon tank. I was seeing a consistent 26.5 mpg on the computer but once calculated by hand it was 27.5 mpg.
Anyone else run it low? I usually try not too do it often as the fuel cools the high pressure pump. Otherwise I might experiment when carrying a spare gas can.2016 Envision Prem ll.2013 ATS 2.0T, 2007 Saturn Sky 2.4 Turbo -44 mpg-top up,2004 Saab 9-5 Sport Combi - JZW Stage IV
