Mobil 1, Quaker State, or Pennzoil

[Jasonsupafly]

Hey all. Ive always used Mibil 1 full synthetic oil in all of my vehicles. But I was in my local Advance Auto Parts this weekend and saw that they have their Quaker State Q Advanced and the new Torque Power both fully synthetic on sale as buy 1 get 1 free. They also have the Pennzoil Platinum full synthetic as buy buy 1 get 1 free. where im at they all run close to 6.00 a quart.. Im due for an oil change now and was wondering how these other oils compare to the Mobil 1 ive always used. And if i switched to one of these other fully synthetic oils would there be any chance of any thing being or going wrong by doing so ? I would save roughly 18.00 by taking advantage of this deal.. I would go back with Mobil 1 at the next oil change for im sure this deal wont be run to often here.. What do you all think about these other oils and is it even worth saving the 18.00 to do it ? thanks in advance
