I just purchased a 2012 SEL ecoboost, I seem to recall one artcle that claimed a pump would circulate coolant after engine shut down to cool down the turbo, I don't hear any pump running after I turn off engine. Does anyone hear a pump running? i assume article was mistaken but if I have a malfunction of this nature, it might only show up years later due to coking of oil in the lines.
I must say, due to web research, i knew not to expect 30mpg on highway, but at the same time, a few years ago the whole MPG estimate process was revamped to represent real world results, they even published revised estimates going backwards many years. obviously a flawed or failed effort.
