Question

What is more volatile? water, engine oil, diesel fuel, or gasoline?

Answer 1

Technically, I believe it's diesel. However, you will get the biggest whoomph off of petrol if you stick a match to it.

This is because petrol evaporates into a heavier-than-air vapour and sits on top of the liquid. This gas gives a much better explosion than any liquid fuel would.

So I think the volatility scale goes thusly:

Diesel

Petrol

Four Stroke Oil

Water

But that the ease of explosion under CTP (normal) conditions is as follows:

Petrol

Diesel

Four Stroke Oil

Water

For practical applications, water is as good as completely inert.

Answer 2

Gasoline by far.

===

In terms of volatility, they are

(1) gasoline

(2) diesel (Kerosene - same thing)

(3) engine oil

(4) water

Good Luck...
