Ever since I purchased my SC, every time I filled up, the fuel range gauge always gave me a number around 340ish miles. Today, I did a long trip from north of Atlanta to Eastern NC, and I stopped to get gas after traveling 412 miles. The range gauge said that I still had 32 miles left of fuel. When I filled up, the gauge said 348 miles of fuel. Has anyone received a higher number or seen the range increase after each fill up?
