This is what happened to a Karnataka MLA, whose brand new Volvo XC90 got filled with diesel instead of petrol.
The horrific outcome of putting the wrong fuel in your car is something we’ve all grown up listening to. But, imagine if you’re in a hurry and you just let the employee of the fuel station know that you need INR 500 worth of fuel, missing to specify which one, only to later realize the wrong fuel has been filled. What would you do?
High precision petrol engines would choke up if filled with diesel and similarly modern diesel engines are also extremely sensitive to fuel quality. These incidents could damage your engine easily. However, if you realize your mistake quick enough, you could save your car. Here’s how.
Symptoms of diesel in a petrol car
So, how and what could go wrong when you put diesel in a petrol car? Fundamentally, diesel is much heavier than petrol and therefore relatively more oily. Initially, it is bound to impact the fuel filter. The fuel filter will clog up almost immediately and your car should begin to stutter and stall. Next, your spark plugs will foul up with soot build up because diesel will get mixed with petrol. At this point, your car will emit a lot of white smoke and ultimately lose all its power and come to a standstill.
Symptoms of petrol in a diesel car
Diesel engines are way harsher than petrol engines when it comes to the wrong fuel. Putting petrol in a diesel car will burn a deep hole in your pocket as they are equipped with technology such as the fuel injection pump that is dependent on the diesel’s lubrication properties to function. Even the rubber seals in the diesel engine don’t welcome the high cleaning, drying properties of petrol. It’s even difficult to diagnose that petrol is filled in your diesel engine. The symptoms expected is that the car will emit black smoke due to the unburnt fuel, eventually leading to a complete halt, post which the car will not start.
