I have a 08 ford ranger sohc v6. I don't pull anything heavier than a quad and that's not often. Since finding this site I have become obsessed with oil lol. I have been running PC synthetic 5w30 but I can get the supreme "dino" for almost half the cost. My oci is 8000km with syn if I switched it would be 6000km. I guess what I am getting at is does anyone have any thoughts on PCs dino flavour of motor oils?
