I can think of just one consumer-oriented car that will run on virtually anything combustible. Chrysler's Turbine car concept from 1963 was probably the first "flex fuel" vehicle. Users reportedly ran the small turbine on fuels ranging from gasoline and AvGas to perfume and whisky. Turbines are one matter, piston engines are quite another. Most require at least a good approximation of their intended fuel, not Crown Royal. I've accidentally run a Studebaker V8 on 2-stroke pre-mix, which proved smokey but far from catastrophic. Will a Porsche Boxster run on blended Canadian whisky in a purple bag?
TechRax approached this problem no one has ever asked without any apparent preparation, just a willingness to dump stuff in a gas tank and readiness to lay blame on the car rather than their idea. These guys have also tried to run a car with bleach (and a quarter tank of gasoline), so we may not be dealing with top notch science here.
Unsurprisingly, this attempt was an utter failure. After getting the Porsche stuck in the mud, TechRax found the Boxster would not start. Their mechanic found that the fuel pump had failed, after which the video host declared that the Porsche was "junk" and "nothing but problems." Adding those to other spurious claims, such as "Porsches tend to turn into fireballs in accidents," doesn't do a ton for their credibility. Hopefully the new owner is able to make something of this Boxster, or at least use it for parts.
So folks, bear in mind that your fuel pumps don't care for Crown Royal. If you're truly pinched for fuel try something your Porsche will recognize- such as schnapps.
