deseasel 2 wheeler.

You didnt watch mythbusters then? They tried a full, half empty, and alm,ost empty tank. With everything possible that fired bullets. Absolutely could niot get a fire even though they turned it to swiss cheese...

Again, mythbusters tried an absolute arsenal of stuff. Shotguns, different sized riffles, different types of amunition, machine guns etc etc. They couldnd get a fuel tank to ignite. Thats just hollywood.

Who knows where next or how cold it will be...

You dont see many unless they are paid too...

Harriers use JP8 or JP4.

Which is just fancy name for well refined kerosene with a few additives and anti static atc. But your car will run on that too however badly. Run quite well though if you lower compression and retard timing. At a push almost all jet engines will run happily on deseasel too. But diesels and turbines wont run on petrol.

You need a source of ignition, if what you say is true then fuel tanks would never burst into flames on impact. They do, in some circumstances, they just don't do it Hollywood style. My experience is that you really don't want to be near petrol in such a situation, diesel is more tolerant but will eventually form an explosive fuel/air mixture. If it didn't it would be useless as a fuel.

Nothing has used JP-4 since the mid 90s. The Harrier uses JP-8 which is simply the mil. spec. version of Jet A1 and they are both AVTUR.

JP-4 was a mix of kerosene and gasoline. It's no wonder that you can run a petrol engine on it since it's very similar to TVO.

Indeed, which is why it's one fuel for the battlefield as much as possible. Even tanks tend to run on JP-8 nowadays.
