B20 first timer

[99bigred]

tomorow i am going to try out a tank of b20 for the first time. I am going out to a race in the desert and have to drive right past a b20 station. Is there anything i should know before i try it? Should it give me more power and mpg?
thanks

I think what I read about biodiesel in general is if you've never run it before the biodiesel will actually act like a cleaner. It will clean the inside of the tank and remove any residue/stain left from the years of diesel in the tank. In turn this "cleaning effect" will dirty up and can possibly clog the fuel filter. I don't know how much truth there is to this or how long a filter will last but I'm sure I read it somewhere. Try doing a search on the effects of switching to Biodiesel just to make sure. I'd hate to see you out desert changing filters. Maybe someone who has used it and is more knowledgable about biodiesel will chime in and help out.

Carry an extra filter, 20 isnt as cleansing as 99 but it cant hurt to be prepared, I'll be switching over in a month or so when the local joint gets it, I've read it takes 2-3 tanks to get the crud out, then you get the benefits having everything running clean.
But then I read it on the internet...........................

I run homemade B100 in the summer, and B50 blend in the winter. I would give it 3-4 tanks and change the filter but have the new one on hand in case something does happen. If you have used a biocide in your fuel tank recently, you wont have an issue of filter plugging becuase your tank is already clean. Bacteria and fungi that grow in untreated diesel fuel, the Methyl Ester fancy term for biodiesel kills, breaks off the fungi almost immediately at B100 and if you have a dirty tank it will plug a filter. But at B20 you wont have instant problems it will be more of a slow death and take it 3-4 tanks to flush the system. But as I said if your tank was clean to start from using a biocide before you wont have issuses period.
