We have determined that Warren makes and packages the Peak dino oil for them. You might want to put in a call to Warren, and see if they supply the synthetic also.
I would bet it is VERY similar to the Walmart Supertech product, I noticed they have a new full synthetic in a clear bottle.
I'm running their dino product in a couple cars, I like that it is a little thinner, my engines run more quiet with it. I paid $8.99 for 5 quarts.
