whats the difference between B99, B100, B20 biodiesel and WVO??

i thought WVO was considered bio diesel, just made from waste veggie oil?

if they were the same, why would i want some bulky, lame oil tank in my truck? why couldn't i run just WVO in my factory tank? do people only do this in colder climates, where they can switch between dino oil for cold temps?

 

WVO is simply waste vegetable oil that is filtered well and usually heated and run like that as fuel. Most WVO set ups are set up to start and shut down on dino diesel or bio so that your injectors and pump don't sit full of WVO which could gum up the works. Those setups have two fuel tanks, one for WVO and one for diesel. WVO doesn't flow well through the system unless it is well filtered and warmed, so that's why the extra tank and parallel systems. Depending on who you listen to, you can mix small amounts of well filtered and clean WVo into your diesel tank without trouble. I haven't tried that yet, but have had great luck so far with commercially produced bio, up to almost 100%.

Biodiesel is vegetable oil that has undergone a transesterification process. The glycerol is broken out of the oil and replaced with methanol. Bio diesel can be run in many if not most diesel engines without the need for separate tanks or any other mods. It can be hard on some rubber parts, especially if it has not been well washed and dried to get the free methanol out. When you see rigs advertised as "biodiesel ready" it usually means that the rubber lines and seals have been replaced with Viton. Bio can be hard to run in cold weather, depending on what it was made from and how well washed and dried it is.

B99 is basically 100% bio but it has 1% dino diesel mixed in, usually for tax reasons I think. B100 is all bio, B20 is dino diesel with 20% bio mixed in.

Way down near the bottom of my links page is a whole bunch of biodiesel links that will explain things much more thoroughly than I have here.
