i drive a 2000 ford focus with an I4 8V SPI engine w/ 94,xxx miles. it gets good gas mileage, but this tank im going for the unthinkable. i can reach 300miles on a tank if i stay off the throttle. i filled up wed. nov. 9th. and i am almost at 1/2tank, i have gone 176.x miles. What i am trying to do is go for 400miles on a tank of gas. wish me luck.
