My truck loves the bio, smoothes right out.

I've got to dissagree Dave.
The pumps his 86 have will push nearly anything fluid enough to get through the single hole hole injectors.
The VE engines (1999-2003) are very flexible as well, but the 4 hole injectors don't like crankcase squeezings and SVO too much.
The pump duse needs very clean fuel due to the close tolerances in the injectors but can run #1 or #2 or b80 with no issue. As you stated, lubricity comes from the engine oil.
The common-rails............. lack of lubricity, even a single gasoline "oops" can cause a catastrophic high pressure fuel pump failure. Look up HPFPF especially on tdiclub.com.
