Knowing just a little about diesel engines helps to understand why misfuelling prevention is such a hot topic nowadays. FuelSure facts can help. Diesel engine cars have evolved from noisy, smelly vehicles into high-performance ones that rival petrol engine cars in comfort and quietness, while beating them in terms of fuel economy. One of the things that helps diesel engines to run so smoothly today is the lubricating property of diesel fuel. Its ‘oiliness’ literally lubricates the moving parts such as the ones in diesel fuel pumps.
Petrol has the opposite quality. It dissolves and removes lubricants. When there is no lubricant, metal grinds directly on metal. Wear and tear accelerates dramatically and worse, particles of metal break off and further contaminate the system. Even if you only partially fill a diesel fuel tank with petrol, your best option is to get the tank emptied and then refill with diesel, accepting the charge for this and the loss of whatever you paid for the petrol, plus any remaining diesel that was in your tank when you fuelled.
However, this is considerably better than having to replace an entire fuel transmission system, which on some new cars can run into several thousands of pounds. It’s also the difference between a minimum of embarrassment on the filling station forecourt and the time it takes for a mechanic or for a specialist service to turn up and fix things, or having your car out of action possibly days if serious repairs are needed. Or you can avoid the problem completely with FuelSure.
This is not yet the end of the story. As technology advances in line with concerns about protecting the environment, more and more cars are being fitted with catalytic exhaust systems that are set up specifically for the type of fuel concerned. Even minor quantities of the wrong fuel mixed in with the right fuel can damage these emission systems and cause problems in tests that vehicles are meeting emissions standards. The wrong fuel will not burn correctly and may be ejected from the engine while still in its original state, rather than as controlled exhaust gases. This unburned fuel can make catalytic exhaust systems overheat. Yet more problems that FuelSure lets you avoid.
If you have a recent car with this kind of system, you may have noticed a similar effect when driving at too low revolutions where the engine cannot burn all of the fuel properly. In this case, the solution may be to change down and drive at the same speed but with higher engine revolutions. However, if the problem is in contaminated fuel because for example no misfuelling prevention device was fitted, the only real solution, as long as no other permanent damage has been done, is to get the fuel tank drained and to refill again with the right fuel.
Whether or not you can still drive a car that has suffered partial fuel contamination depends of course on the degree of misfuelling. If the amount of petrol that has been misfuelled into a diesel tank is less than 10% of the total fuel (meaning that the other 90% is diesel), you may be able to drive or at least keep repairs to a minimum by having the tank drained and the system flushed. Get a professional’s advice or contact the manufacturer before making any decision. Better still, fit FuelSure beforehand instead.
Nonetheless, cars in such diesel misfuelling cases may have suffered damage to fuel systems, advanced wear and tear inside the engine and degraded performance, as well as increased fuel consumption. When you add up all of the effects over time, the total cost can mount up to hundreds of pounds and keep on rising for as long as the car is being run.
The alternative is to use a device to consistently prevent misfuelling, and that can be fitted easily and inexpensively to the filler neck of the fuel tank - FuelSure. Not only that, but once acquired, there is no further cost to the device, no further danger of misfuelling and therefore no risk of continually mounting costs due to damage sustained by putting the wrong fuel in the fuel tank.
