Question on typical gas milage and possible problem(s) if low milage
I am a senior citizen and recieved this 1987 Nissan Maxima as a Xmas gift by my family. The car was in great looking condition and has only 90,000 miles on it. My problem is the gas mileage is only 10-12 miles per gallon. Is this typical for this model, as I had hoped it would give a lot better milage. If it is not typical, is there any problem solving anyone can suggest to diagnoise the problem. I am not a mechanic and live on a social security (fixed income), but need the vehicle for appointments and part time work. Thank you
