Actually, your little joking happy face emoticon was correct. I DO need a totally mobile rig. I live in a condo.

My F-250 has plenty of bed space. I need some extra weight in the back anyway.

There's a challenge then!
Never seen anyone do that before. I depend on settling a lot in my setup, guess that is a bit out of the question for you.

Do you not get a garage or can you not use someone else's or hire it off them?
I think having everything in the truck will pose a whole load of rarely visited problems to overcome!

Sounds like an ideal application for a centrifuge. Youc an even use a pulley driven engine power takeoff. Process fuel as you drive.

My condo has secure underground parking, but they won't even let anyone change their motor oil, let alone dewater 50 gallons of WVO.

I might try to rent a small area from someone, but I would want to do it on a utility trailer in case they change their mind and ask me to leave. That way, I can just hook up and drive away...

Absolutely, Burb! A CF is definately in the plans. I want a bigger CF than usual though. I want the extra processing capacity so I have room for expansion. You never know who else might need clean/dry WVO.

I've got this old guy where I work who commutes for about 1 1/2 hours each way every word day. He's driving an old 12 valve Dodge and spends a fortune on fuel. I'm trying to get him into veggie.

In general, I have found that if both fluids are above the lowest one's cloud point, it doesn't matter which one is warmer.

Also a 50/50 mix of VO and diesel will "splash blend" better than 100%VO.

How much drier is kerosene, and how much more additive would it need to get to D2 specs?

Kero is not drier = less water. It has lower lubricity than Diesel since it has no additives. I would add at least 5% WVO or bio to kero to get good lubricity exceeding Diesel specs.

Matters what type of CF you use. The larger spinning bowl types I dont think you can use while driving. The shakes and wiggles are liable to keep knocking it off balance (liquid inside changes shape etc.). The engine oil spinner types like dieselcraft are designed for use in a moving vehicle.

I cant see any other type working in a mobile rig.

I like to second this assumption by saying, in a moving mobile rig. :)

Ok, that is what I am getting. What is the adjective for less lubricity if not drier?
