    I've been reading around, and I've stumbled across a score of people using Jet A1 fuel instead of Diesel for their cars.

    Now, A1 fuel runs currently between £0.75-£1.00/ltr, and apparently, it's functions almost identical to diesel, except it doesn't have as much lubrication to it, which could cause problems with fuel pumps designed for diesel. So people are using a bit of 2 stroke oil every few fillups to keep things nice and smooth, and it's working perfectly fine for them.

    Is this something anyone has tried? 80p / litre kept in some big barrels in the shed after a trip to the regional airport sure does sound good compared to £1.40 at Sainsbury's!

    Sounds plausible but illegal as you'd be evading tax - unsure about adding 2 stroke intermittently tho - if it's doing anything useful in your pump I'd reason that you'd need a constant amount of it.

    I only know that airplanes with diesel engines regularly fly on Jet-A/A1. In fact, more of them probably fly on Jet-A1 than actually on diesel, since jet fuel is a lot more readily available at airports.

    No idea about cars, though.

    Unless the law has changed, you can have something like 2500 litres of fuel tax free per year. If you work out how much you drive, you can dilute the oil with diesel to keep yourself under the 2500 litres/year, avoid the majority of the tax, and keep your engine in good running order. It only works with older diesel engines though, if your engine uses the newer, high pressure injection system then it'll probably grenade the engine.

    Jet A1 is basically kerosene which is a slightly heavier fraction than diesel.

    I am not sure how you would go about going to an airport and saying give me a tonne of diesel though.

    It is harder to get in the distillation tower and cleaner than diesel so the fuel is actually more expensive. It is just the tax on diesel that makes it insane!

    Many airports have self-serve card-locked gas pumps. So you can just drive up, swipe the card, type in an amount, and pump it.

    The nozzle may not physically fit into the car, though, so pumping into a container may be a better idea.

    It may look a little suspicious, but I don't think anyone would care.

    Pilots don't care because it's none of their business, airport owner certainly don't care because they just want to sell fuel, and police isn't usually at airports (this is assuming this is actually illegal).
