It's an old bottle of "Comma Universal Brake Fluid DOT3/4" that has been
around for several years and I wouldn't trust for its intended purpose
any more.


Some of the old stuff used to strip paint so I wouldn't trust it to
clean anything.
It was also very flammable and was what caused fires in crashes, not the
petrol. You can pour petrol on the exhaust manifold and it won't ignite,
the old brake fluid would ignite.

OMG

https://en.wikipedia.org/wiki/Flash_point

For petrol it's around -43C. For DOT 3/4 its 125C

You have excelled yourself this time.

Even the "old stuff" was either glycol or heavy mineral based, possibly
some vegetable oil. None had a flash point lower than petrol.

You do know the difference between petrol and diesel? Perhaps you're
getting the two muddled up?


It's auto ignition point that is under discussion though which isn't the
same as flash point.

I've certainly seen the demo of brake fluid Vs petrol on a hot manifold. I
think it was on "Fifth Gear" many moons ago. Dunno if brake fluid is still
as dangerous though.

Petrol is funny stuff. You can't set light to it with a cigarette end
(which rather makes a mockery of all those scenes in films when someone
flicks a smoking fag-end into a puddle of petrol setting it slight).
