So far from what I read, I think my inline filter just before the IP is a great solution for these WVO IP problems.
I think a lot of people get WVO and Biodiesel confused. I don't think vegetable oil eats anything.
WVO is waste vegetable oil mostly collected from restaurants w/fryers
New oil is used as well but I like recycling and it's free
The oil is filtered and then
heated onboard to match the viscosity of the diesel so the injector will atomize it and it will flash/vaporize/combustion
Biodiesel is a chemical process where the WVO (or new veg oil) is mixed with methanol and lye to make a chemical reaction to remove the glycerin, then the lye is washed out of it and you have a fuel close to diesel that
does not need to be heated onboard
Biodiesel has a lot of waste product and uses a lot of energy to make it.
I run WVO because I can get it on the road, low investment cost and no chemicals.
An interesting bit of info, Rudolph Diesel invented the Diesel engine to run off straight veggie oil. He had this whole vision of counties growing there own fuel and being sustainable. He "disappeared" and his engines were tweaked for #2 oil, which they named "Diesel fuel". What a kick in the ass!
