How reliable is biodiesel?

I want to start making Biodiesel fuel for a truck i'm about to get but i want to know how reliable it is? I know it clumps up in cold weather but would that apply in northern california, where it only gets to a low of 65 in winter time?

Biodiesel is generally as or more reliable than petrodiesel. Performance aside, it only clumps up if it contains glycerin, which is usually filtered out during the manufacturing process. Check with the maker or if you make it yourself, use instructions that include the filtering.
