[Vwdiesel] WVO question

[mikitka]

Been thinking of running on WVO, the local burger shop in town uses soy oil
in their deep fryer and switches out about 9 gallons of oil every 10 days.
I did some searching online but didn't find what I was looking for. Question
is can you run a mix of WVO and diesel safely in your tank.  If the WVO was
filtered can you run say 5 gallons of it to 9 gallons of diesel with no
problems?  What issues will I run into running it like that. Just a thought
until I can get my Jetta set up for it.

Thanks,

Nick
