This is kind of a catch-all thread for me to throw in things that I've experienced running on biodiesel and see if anyone out there has had similar experiences.
When I stared getting serious about driving "greener" I got my hands on a 2001 Prius, which was a great car for me. When the 2004's came out I was one of the first in the Denver Boulder area to get one and loved that too. I could carry all kinds of things in it, it rode great, and was a really good car. Until I left it in the sun with the windows closed... luckily I did it while I was still under warranty so the $2,000 computer repair was covered. But realizing that keeping it going might get expensive, so I started looking around at biodiesel.
One of my motiviations was that - bottom line - even the Prius uses petroleum. If you want to get totally off petroleum, you have to go with biofuels and biodiesel is a great way to go. So I found myself a 1995 Cheverolet Diesel pickup (known as the K2500 Silverado). Another motivation with getting a pickup truck was that I treated my Prius like a pickup and might as well go full-bore and get a real truck. And lastly, I wanted to run on veggie oil and I figured that putting the GreaseCar kit into my truck would be somewhat easier than getting it put into a VW or something like that.
So I got my truck and started running it on B20 (since I bought it in February), and stayed with the B20 until the weather warmed up. I ran on B100 for several months and then switched back to B20 early in October.
B100 is expensive, but in my mind it's worth it. It doesn't smell bad like dino diesel and even B20 do. You spill it on your hands - no big deal. Washes right off. You spill it on the ground - no big deal. It's just vegetable oil. You store it in your garage - you don't even know it's there.
I'm really hoping that the price goes down as supply goes up, but I'm willing to keep plugging away at $3.49 a gallon. (By the way, it was $3.09 in Salt Lake City. Boulder is very expensive comparatively, but that's not unexpected =)
More to come about my trip to California running on B100...
