I wouldn't begin to worry about it not burning. You can run that engine off straight motor oil as long as it's warm enough. Numerous people burn used oil in diesel engines, that's the whole wmo/wvo free fuel craze. It's fallen off in recent years because of the cheaper price of fuel made it less attractive.
The big thing those guys do that you're not, is they filter it pretty extensively, which is why I mentioned spare fuel filters for the trip. Those wvo/wmo guys also go through injectors and fuel pumps pretty quickly too, due to the contaminants present in their fuel.
If you're estimating 5 gallons of oil being used for the trip, buy/use the cheapest 15w40 oil you can find, and get after it. As long as you have half a tank or so of diesel, those in the alt fuels crowd run their blends at way higher ratios then what you're going to have.
