To be fair I should have expressed it as a range of 200 to 600 degree C, (UK fuel closer to 550). However, the point I was making was that with out a source of ignition petrol is safer than diesel and loads safer than brake fluid or hydraulic oil
Spot on - lot of people don't relaise that.
Jono is quite right about the match trick - a lighted fag will also be put out by petrol.......
Talking of brake fluid I had direct experience of that - I had just bought my beloved Alfa 75 - 30,000 on the clock and well pleased with it. A few days later I had stopped on a steep hill - narrow country road - suddenly loads of smoke coming from under the bonnet.
I always carry a few bottle of mineral water with me - opened the bonnet and saw things well alight - chucked all the water over the fire and luckily we were right next to a resevoir - mate kept going back for refills.
When the fire was out I saw what had caused it - somehow the brake fluid resevoir had blown off the cylinder - brake fluid right onto the tubular exhaust manifold. How it happened I will never know - the breather hole was clear!!!
I was very lucky - the ONLY damage was a tiny bit of insulation burnt through on one wire - bit of tape around that and the car did another 140,000 miles no probs at all - still have it!!!
