My car seems to be running fine,however, I have been consistantly losing gas mileage since this past summer. It was averaging 26 miles per gallon, now I am down to apx 20 miles per gallon. I have new tires,so I am sure that is not the problem. I am the only one who drives it, and I faithfully keep up oil changes. Any ideas??? Thank you so much!!
