have good luck with plain 'ol dino or blends in the extreme cold temps ( 0 to -20f)? The reason I ask is because I did a little non-scientific testing in my freezer, which gets down to -13f. I put a group III synthetic in there with some diffrent dino oils and found that they are all about the consistency of medium warm honeyat that temp. One didn't really have an advantage over the other, all about the same. Just wondering what dino everybody uses or has had good luck with when the mercury dips below the egg. Thanks
