I've poured 9 gallons of soybean cooking oil unfiltered from the Costco jug into the SDL with the reserve light on and the pointer on E. I've also tried it in various proportions with pump Diesel. No problems starting in San Jose, CA winter. I put some oil in a cup and left it outside as it dipped to freezing. The next morning at departure time it is was liquid (the oil, not the cup). Did it gel overnight? Will it gel in the tank?

I don't notice any difference in consumption or performance. I haven't checked the rubber lines at the tank but everything under the hood looks good.

Soybean cooking oil is ~$2.80/gal at Costco and Diesel is ~$2.65 at the truck stop so we're almost to the even point except for the toll of hoisting 35 lb jugs. OTOH Costco doesn't winterize cooking oil The SDL really doesn't like winterized fuel.
