Petrol contains octane. Burn it in oxygen and you get
2 C8H18 + 25 O2 becomes 16 CO2 + 18 H2O

The CO2 warms the atmosphere. The H2O is water, which condenses in the cold air and forms steam.

Happens in all fuel burning engines, petrol, diesel, kerosene, food. That stuff trailing behind aircraft, its the same - condensed water vapour trails, or con-trails.

Nothing to worry about.

Yeah apologies I posted on my phone, didn't realise that I left bits out.

Well that's a relief, just wanted to make sure just seem to notice it a lot more in this car than any previous car ive had.

Thanks for the reply :)
