Accidental misfueling of vehicles may happen for several reasons. Considering how diesel fuel nozzles are designed not to fit into an unleaded gas tank; the occurrence of filling diesel in a gasoline vehicle might be so hard to explain. However, a rare lapse in concentration might result in this ugly situation despite the precautions put in place. Gas engines usually come with a combustion chamber that requires a spark to ignite.

Diesel fuel is fairly thick which makes it practically impossible to combust by gas engines. The vehicle may run a few distances before it stops running as a result. Fortunately, this occurrence will not cause lasting damage to the vehicle system. That is if a proactive approach is taken immediately after the error is discovered.

To salvage this situation, the first step is to pull the car over and don’t attempt to start it. At this point, the damage is temporary and could easily be rectified by a professional mechanic. The resolution is usually to flush the whole fuel system to rid the vehicle engine of the diesel; and fuel it appropriately with gas. However, the extent of the damage will determine the cost but it is relatively expensive.

After this process, the vehicle can be safely fueled with gasoline and it would resume normal functioning without problems. 

What Are The Likely Problems To Watch Out After Fueling A Gas Car With Diesel?

Accidental fueling of gas cars with diesel will usually result in abnormal emission of smoke. Additionally, the octane rating designed as a measure of resistance of fuel.

Gasoline-powered vehicles are generally more attractive and are usually lower in price compared to diesel-powered vehicles. Also, Gas engines are less noisy. While vehicles fueled with diesel tend to make more noise. Largely due to high production of power. However, the advantage of diesel-powered engines become significant when the need to carry heavy loads arises. Which is why all heavy vehicles like trains and ships use diesel power.
