Before I went to bed last night I had one bar left on my fuel line. This morning when I started my Smart the reserve light was blinking. I drove down the street to the Shell station to fill up. 91 octain at $3.979 a gal 6.925 gal pumped $27.55. How much dose it cost you to fill up? Funny thing $27.55 won't even fill up my toyota echo with 87 octain.
