Compared to thin, volatile petrol fuel, diesel is much heavier and oilier. These basic differences in appearance reflect how the fuels behave when subjected to compression or ignited,, as do the engines that are designed to run on them. While most drivers will never need to worry about these relatively arcane details, understanding what to do and why after putting in the wrong fuel in Banbury is something that any local might benefit from.
The most important thing to realize is that petrol and diesel engines are very different and that an inappropriate fuel will often do much worse than simply impede the vehicle’s ability to run. When introduced into a petrol-burning engine, thick, oily diesel has a way of gumming up some of its most important parts, leaving a residue behind that can clog injectors and valves and even contribute to the premature failure of gaskets and other seals. Petrol that is added to a vehicle that is designed to burn diesel can be even more troublesome, stripping away protective lubricating layers and causing moving parts to grind themselves into pieces.
While these problems can be serious, they can only crop up insofar as fuel is able to move from a vehicle’s tank further along into its power plant. What this means in practice is that drivers who notice immediately that they have added the wrong fuel and who thereafter refrain from starting the engine up can often escape with relatively small repair bills. In many such cases, all that will be required will be to drain the fuel tank and perhaps to do the same for fuel lines nearby.
On the other hand, starting up an engine after the wrong fuel has been added will typically lead to much more serious consequences. As fuel of the wrong kind makes its way from the tank into the pump and other parts of the vehicle, it will do more damage as it goes. Even then, drivers who notice the mistake before too much time has elapsed can hope to keep the damage to a minimum by powering down as quickly as possible. While it is possible to do great harm to an engine in this way, being aware of this possibility and knowing what to do to counter it can help.
