Using the MPG-DIC technique, my 2009 XFE sedan got 35 mpg on the last two tankfuls. I think the technique had a serious effect of around 2 mpg.

DIC was my last innovation. I had already switched to synthetic crankcase oil, wheels that are five pounds lighter/wheel, and modestly increased tire pressure. The tire pressure is 38 psi.

thanks for the tips
