I should be running #2 diesel

Stop spouting misinformation and scaring the poor guy!

Don't for a minute think #1 diesel is "like lower octane fuel" compared to #2 or one is better or more refined than the other. It doesn't have less lubricity. I will not harm fuel systems. It will not harm an engine if driven hard. It does not burn way faster.

Diesel fuel is diesel fuel, whether #1 or #2. Both are refined and sold by oil companies for use in diesel fueled engines. If there were issues with running #1, they wouldn't sell it. #1 is better for winter at the SLIGHT expense of performance. THAT'S IT.

Yep, slightly lower BTU and will run to much lower temps without turning to goo. I got #2 over in Idaho at a truck stop that had both. Over on the west side of the mountains we never see #1. It does not get that cold.

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.

Very true. Tolerances in HPCR fuel systems are ridiculous. And every single manufacturer has gone to HPCR, and if not they will soon because of emissions. There will be a lot more "oops" in the future. I call it job security.
