QUESTION 1:
im new to this, i dont get why you would pay more for biodiesel $/gal if normal diesel is cheaper.

if cost is a concern i want to go with WVO.
(assuming i can find a place to reliably get WVO)

QUESTION 2:
if i am going to get a new truck to run WVO, what do you guys think about
the GMC 2500HD duramax? What are recommended trucks for SVO/WVO

I heard the WVO kit needs another gas tank for the WVO, --
i think older GMC's/Chev's (2001?) have stock dual gas tanks, --
QUESTION 3:
can i just convert one of the existing stock tanks for WVO?

Thanks!

I am running bio for the lubricity. Less pollution and helping the farmers a bit are nice fringes.

I'm running ~33% WVO filtered and water free added to my diesel tank now that it's warmer. I'd recommend a prefilter fuel heater to anyone looking to add WVO into their tank.
Some of the farmers around here run pure cotton seed oil in their PS diesels all summer.
