Hello everyone,
Happy holidays! I have a 1990 325i convertible and I'm averaging about 15MPG, is this common? If not, what can I do to improve fuel economy? I've already replaced my O2 sensor, as well as temp sensor. Could the issue lie with the fuel pump? fuel return line? or would I need an adjustable fuel pressure regulator or perhaps a fresh set of fuel injectors?
Thank you for your time and assistance.

Is 15 MPG normal for my chariot?
