Now the deal is I know vegetable oil is flammable but it's got to be pretty darn hot. I bought a 50 gallon sprayer that has an electric motor that hooks up to a battery for the back of my four wheeler. The whole reason to buy in this $300 pump was to spray Mesquite out in the pasture. I've had this sucker in the garage because for a year after reading the directions that says do not use flammable liquid. So of course diesel is out of the question but vegetable oil is an option to mix with remedy. Any advice? Working in the restaurants we heat our oil up to 350 degrees with no problem.
