Want to save gas?
Re: Want to save gas?
Not that I'll be driving my XF on the winters salty roads here in Wisconsin but the formulation of gas is better in winter here not in summer.. ( winter hard starts, cold = better gas) I've noticed a big difference in getting much better gas mileage in winter.( with my other cars)
Is it me or are we seeing things in this thread that defy logic?
