I always fill my Mazda6 right up to full when it gets down to about 1/2 way between 1/4 tank & empty,which usually lasts approx 3 weeks,but just lately I've been topping it up more often while the prices are lower (thinking they might rocket up again soon).I'm now wondering how much of the potential saving I am losing because i'm carrying more fuel weight around for longer :rolleyes
