What I suppose is slowing me down is that my drive is something like 30miles each way, so the first few minutes and last few equate to around 20% of the trip. So that means I'll probably end up making bio for that portion, but if I already have to make some.... Another thing is if I get a WVO tank I'd want it to hold about 20gallons which I believe would make it 10" deep, then 20gallons of it weighs approx 180#, which could be enough to make the springs start sagging (or in my 84's case, there would be no more spring). Finally I'm not keen on drilling holes in my trunk and running new coolant lines the length of the car. How do you know when your WVO tank is getting empty? Surely you can't wait to start sucking air as then you could be SOL, do you just have to keep looking in it or is there a way to get a gauge sent up to your dash? (I was wondering if there were a switch that could be wired up to a sender to have little LEDs to light up the amount in it.) Do you guys boil the water out?
With all of that said, I finally bought some filters from McMaster Carr, I got 7 for $23.
I bought one real expensive one and six decent ones, the decent ones filter to 1 micron, but the expensive one is supposed to last 3X longer but filters in the 1-5micron range. Eventually I should end up doing SOMETHING with some WVO.
