Hi,
This is my first post here so please bear with me.
Bought a brand new 2009 VW Jetta TDI in May of this year. Before I bought the new one I test drive several 2006 TDI's that the computer showed avg MPG of high 40's to 50's. My car gets about 36 avg MPG. How can I improve my MPG??
Drive it more. It's not even broken in yet.
it has over 15,000 miles on it now
Still not really broken in. Keep driving. That, and keep your foot out of it if you want better mileage.
