Mike689 Registered User Join Date: Jul 2015 Location: Monterey Posts: 46	Very low mpg, help plz Hello I just bought a 01' Boxster S about 2 weeks ago. I changed the oil a few days later and I drive at around 3k rpm. I'm still only getting about 16 mpg and I drive mostly on the freeway. Am I doing something wrong or is it the car? and how do I fix it? thanks!
