full synthetic oil?

-
Canola oil. It has zero trans fat.
And who wants a fat trans?
Seriously, i use full synthetic in all of my modern vehicles, the old ones get dino oil with a zinc additive because they use and leak oil.
If/when i build a new engine for my car, it will be well broken in with dino oil and the zinc additive and then switched to synthetic.
 
they still had zddp in the oils though, now there is almost none. even rotella has brought those numbers down
