Just get some Bio from boat supply and add a little and you are good to go. Look at all the boats in Marina. Alot are diesel and water all around them. Keep the water out and you are good to go. And this stuff is a B.#%$ to light, not near as bad as gas.
I keep two 2 1/2 cans in my trunk and use it every six to nine month's. Never a problem.
If I see a station and they are .25 to .35 cent higher than everyone else. I got another hundred mile to find cheaper.
Check the net there are site's that monitor diesel prices. Trucker use 200 to 400 gal. so they watch this.
