I know how to make high octane fuel and it isn't very easy, especially in 1885. You'd need catalysts, high-pressure reaction vessels, and a distillation column. I doubt that Doc Brown would even have known the process well enough to know where to start.

And even if he did, it would be unlikely he could accomplish this in the 5 days he had. Even getting a sufficient quantity of crude oil would be difficult to get in that few days.
