I have used the Vavoline and even Quaker State brand of these types of oils and I have no complaints. My car that I used it in (before sold at 120k miles) had it in all the time, never burnt oil. It is though a blend, and not a straight syn.

I don't know if it is better for the car or not, but it worked well for what thats worth. <img border="0" title="" alt="[Wink]" src="images/icons/wink.gif" />
