dual tank for southern california weather?

So I've been playing with the idea of running WVO on my 85 300d. I've reached out to a few vendors and they've said to go single tank because it is the easiest. I'm not necessarily wanting to go the easiest route. I prefer to have some longevity of my engine. Assuming that my WVO is good quality, does running a dual tank (start on diesel, shut-off with diesel) make sense in Southern California? Overkill? What are your thoughts? If I posted something that has already been posted, please point me in the right direction...

Dual Tank.

Injecting VO below 160 degrees results in a poor spray pattern and incomplete combustion. The result is piston rings stuck in their grooves and all the problems that come along with that.

You could also investigate blending. I have no experience with that, but it might work for you in a warm climate.

I like two tank

And it is not that difficult. I live in south flordia, S Cali is cold by comparison, most local greasers run two tanks except a few that have single. Two tanks all seem to run better one single tanker uses water injection I think it made it just as complicated as a two tank.

I vote two tank!
