I am just wondering if anybody knows how much gas they put in their bmw 740il like every 10 miles or 20. I am asking this question cause i used to have a problem in my car and some people said its the reason why i pay so much for gas, when i payed $10 for gas it would be gone in about an hour or an hour and fifteen minutes so i am just wondering am i the only one who's car takes so much gas.
by the way i know its an 8 cylinder but some people told me still its taking so much
