My goal...............VW Rabbit diesel powered trike !!!!! A suppose one could get rid of another wheel !!!https://www.youtube.com/watch?v=qmZ1lCtgTzg
I try not to let the fuel tank go below 1/4 for these reasons and I try to take advantage of cheaper stations and fill up completely when I have the opportunity of being near one. The price difference can be huge and the cheaper places seem to have better quality anyway, being that they sell a lot of diesel and turn it over fast.
