I have switched to Optilube Summer Blend and Optilube Winter Blend for my diesel truck. Independent test results are listed here:

They have a more expensive product (XDP) that scored even better. I am very pleased with the performance so far down to temperatures in the teens. Interesting to note that some products tested performed worse than no additive at all.
