ok I own a 2000 SEL and I've been noticing horrible fuel milage for awhile now. Anyway, I drove to Toronto from where I live. I filled it up right before I left and when I arrived in Toronto (350Km) I filled up again and in costed me $33.00CAN. I was driving really slow.Then the next day I drove straight back doing crazy speeds on the 401( I was WOT many times) and filled up when I got home and it costs $22.00CAN and gas was more expensive! I only burned half a tank! What the heck? It doesn't make any sense! Usually it burns sooo much! Anybody have any ideas? What could this be? Does anybody have horrible millage on a gen4?
