Never a big fan nor have I ever used QS in the past. I thought I would give this new Synthetic blend a try. It has bosted zinc levels claimed @ 1200ppm. Price is resonable and I like the syn blend aspect and the fact it is available in 10w 40.

 

I was in Auto Zone yesterday and they have QS Defy 10W-40 on sale for $3.99 until June 25. I'm not sure if all of the Defy is synthetic. I need to take a closer look.
