I ran the DS version in a Jeep 4.0 and a Chrysler 2.2 and was very pleased. It starts as a thin 30 weight, but doesn't shear too badly over the course of a decent 5k OCI. If I could still get it in 5 quart jugs at Wally's, it would be my first choice in the dino world. But the only local place that carries it has it at synthetic pricing, so I don't use it anymore.
