aircraft fuel is really really cheap. could a car run on it?
would it dammage the car? cold a car be converted? and anyone who says yes if you put jet turbines on the car will be marked unhelpful lol.
asked in cars, fuel, money

It is used in racing cars as it is less likely to explode at high temperatures and doesn't freeze either. It is not good for the carbon emissions either so not wise to use in the ordinary car not if you still want the world here in a few years time.

Heptane (jet fuel) is much more explosive than octane (petrol) : it would be too risky for motor vehicles. Any repairs done on any vehicle that uses it has to be done with special brass tools which don't produce any kind of spark.

Note the difference between aircraft and jet fuel!
I doubt it is cheaper.

DragonsDen answers:

Aviation fuel is not cheaper than car fuels except for the high taxes on motoring fuels. Petrol, less the taxes is about 60p per Litre. aviation fuel varies depending on where it is bought but a main airport such as Luton or East Midlands it is about 90p per Litre. at a smaller airport, for example Sywell in Northamprton it is about £1.30.

As DD says above, the bulk of the cost of petrol is tax.



However, Jet fuel might be cheaper to produce, and yes cars have been built to run on it, using turbine engines.

Rover did lots of experiments with this in the 60s, and actually had working cars but the fuel consumption was terrible.
http://www.rover.org.nz/pages/jet/jet5.htm

Same with Chrysler : http://en.wikipedia.org/wiki/Chrysler_Turbine_Car

More lately, I've seen a Lotus 7 copy fitted with a turbine engine taken from a helicopter. And the video clip above shows that the loonies still occasionally get out of the asylum.

Does this make me unhelpful? =o)



But the sort of fuel used in a typical light aircraft is much the same as standard 4-star fuel, except that the octane rating is raised a bit by adding extra lead. I imagine this would be more expensive than standard unleaded petrol.
(I've heard that mixing unleaded and aviation spirit in a ratio of about 10:1 would give you proper unleaded fuel, but is officially naughty).
And because of the lead, you can't put it in a car with a catalytic converter anyway.
I have no idea what the taxation is on this, but I guess it's less than on a car.

My Dad used to have a Humber Snipe which had been converted to run on paraffin. The conversion was illegal due to emissions (even in the 60s) but basically you had to run the engine red hot.
He did this by blanking off half the radiator.

You also need to start and stop the engine on petrol. Forget to switch over, and it could be a fairly major task to get it started again.

Since paraffin burns slower than petrol, it's still burning when the valves open. So your valves don't last long (maybe only a few hundred miles). Fixing them is an easy job on a 60s motor with lots of access, but not so easy on a modern overhead cam engine.

The kerosene used in jet engines is very close to standard household paraffin.

You used to get tractors which ran on a substance called TVO (Tractor Vapourising Oil) which was also very cheap, and again you had to start the things on petrol.

http://en.wikipedia.org/wiki/Tractor_vaporising_oil

Again, this was based around household paraffin.




But if you want to save money AND be green, use vegetable oil in your diesel engine. Many cars don't require any conversion at all.
And it's legal, up to a certain amount.

Why worry about cheap aviation fuel when an old diesel will run on spent chip fat oil - you just gotta drive between chip shops all the time!!!

That is just sooo wrong - I'd put on soooo much weight and probably spend all I had saved on fuel buying fish and chips!!!
