Re: Ford Escape MPG Mileage Improves!!
This happens with every vehicle - after the first oil change, you should see a slight increase. They say there is no "break in period" with a new car, but they only mean that to imply that there are no RPM or speed restrictions with the new engine; once the engine components settle in a bit you'll see an improvement.
I'll be switching to full synthetic as soon as my '09 4-cylinder gets to 5k, but it probably won't help since the viscosity is already 5w20.
