I have had 100% Synthetic oil in my last 2 vehicles in a row, and I have it in my Escape. It IS better for cold starts, and for sitting for extended periods of time. Warmup of the engine is faster, it allows the valvetrain to operate more effectively, and is supposed to increase fuel economy. I'm likely going to start putting Royal Purple 5W20 in my Escape this winter, as it's surpassed the 100K mark on the odometer.

At the end of the day, you won't go wrong with using either type of oil for only a 3 month stretch...
