Here is the article about Lucas:
Very imformative site, and I suggest visiting their forums as well about oils and such.
Used to love Mobil1 0w20, but I can no longer find it. I'll prolly switch to Amsoil 0w-20, but will have to mail-order.
There's some discussion that mobil moved to gradeIII base in their "full-synth" oils.
I don't use any oil additive. I figured these oil companies did so much with their oil recipes, if the additives were so good, they'd just include it in the oil.
