It cost $192 to fill up my Ford Excursion. I can go 3 weeks between visit to the gas station. It uses Diseal and it was $4.70 a gallon. But as my dh said " Its alot cheaper to fill up a paid for Ford, than it is to fill up a fianced Toyota." Meaning we know alot of people that are replacing their cars to get better gas mileage, but they are fiancing them for 5 to 7 yrs. Do the math. Its going to take along time before that better gas mileage is going to be worth all those monthly payments with interest, plus collision insurance.
And, they are still having to pay $4 plus a gallon for gas.
