Misfuelling, if you don’t know exactly what it means, is when someone puts diesel in a gas tank or gas into a diesel fuel tank.  You might think this is an impossible thing to have happen or that it cannot be a very common mistake.  However, it is more common than most of us realise.

Diesel misfuelling occurs to about 1 in every 4 individuals.  About 2 out of every 4 individuals know someone who has misfuelled their vehicle.  So, how can misfuelling happen so often?  Well, with diesel vehicles it is very easy to pick up the gas nozzle and start fuelling.  The gas nozzle is smaller than the diesel nozzle, which means it will fit in there easily.  Gas misfuelling is less common due to the size of the nozzles, but not impossible.

Most of the time diesel misfuelling occurs because the person at the fuel pump is on their mobile phone, talking to the passenger, or just not paying enough attention.  It is an accident that can be quite costly.

Every time a misfuelling occurs it could cost you £150-£7000.  The difference in cost determines how bad the misfuelling issue occurred.  In other words did you realise your mistake at the pump, call for a tow, pay for the gas, and then have the tank drained?  Or did you drive around until the engine stalled?  If you drive a vehicle with a full tank of petrol instead of diesel, then you are looking at a very costly mistake.  If you realise you put a gallon of gas into the tank and then stopped it, you will not have to worry overmuch about the mistake.  You see, a little gas in diesel will not be an issue.  You may not even have to drain the tank; however you should speak with a qualified professional to ascertain if damage could occur.

Now that we have looked at the problem, you should know there is a very easy solution to misfuelling.  The Fuel Sure misfuelling prevention device provides you with a method to never have to worry about misfuelling again.  The Fuel Sure device has a valve which threads into the top of the tank where you fill it.  This valve will not open unless you have the right sized nozzle.  In other words it does not work with the smaller gas nozzle.  For under fifty pounds you can save yourself thousands of pounds during the time you own your diesel engine.
