I'd like your advice on biodiesel.
First, what are the drawbacks ?

And then the good points.

I notice newer diesel vehicles apparently need Diesel Exhaust Fluid.
The trucks at work use this stuff.
How often is this stuff needed ?
It is expensive !
( And while I'm at it, I realize that the urea in DEF is now synthetic, but who in THE HELL thought of using urine to reduce emissions in diesels ?
Is it the same people that made Premarin for women from horse urine ?? )

Ok.
Back on topic.
So tell me some good and bad about diesels !
I'm in Texas BTW.
