Duluth, great technical article! This is what we need here. Especially since many here do not appear to currently own diesels. I very much appreciated the comparison between AMSOIL and Power Service (is what I buy from NAPA). I did not know PS cost more though. I'll have to run some numbers...
Regarding ULSD lubricity, I've read so many different theories on that. But I run PS octane boost w/ their version of lubricant in the summer just in case. I imagine AMSOIL has a version of that product also? How does it compare?
cheers,
