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...

I`m using mobil 1 synthethic 5w20 in mine and on my next oil change i`m going to be putting in the new pennzoil ultra 5w20.By the way as per ealier posts yes you can switch back and forth between synthetic and dino oil if your car is fairly new it doesn`t hurt anything.The problem with seals and synthetic oil is only if your car has more than 100k + and if you used dino oil all that time than your seals might have dried up over time or have cracks in it. Synthetic oil has a thinner viscosity rating than dino oil or in layman`s terms conventional oil.
