7 Known Issues Of Petrol Cars Explained

Any car can have a problem, but some issues are more common in petrol-powered vehicles. This is because petrol cars have many more moving parts compared to electric vehicles. Another unique feature is that they rely on spark plugs and ignition coils to ignite the fuel. It’s good to know what they are so you can be prepared to avoid or deal with them.

Compared to diesel, electric, and hybrid vehicles, here are 7 common issues you can expect in petrol cars.

1. Petrol Cars Affect The Environment

One of the reasons electric cars are becoming more popular is that cars that use fuel are bad for the environment. Apart from spills, gasoline is a non-renewable energy source, and burning it releases carbon dioxide, which contributes to global warming and air pollution. Even when they’re in perfect condition, petrol cars are still big polluters. If you’re considering buying a car, you might want to weigh the environmental costs of a petrol car.

Electric vehicles are a good option for reducing emissions, but not every car buyer can afford one. Check out our inventory of electrified cars to find a car that fits your budget.

2. Buildup From Old Engine Oil:

Over time, engine oil can build up into sludge inside the engine. This buildup can be caused by contamination or oxidation of the oil. This sludge can cause parts to stick together and lead to problems with starting or idling. If you notice your car having trouble starting or running smoothly, it’s a good idea to get an oil change.

To avoid buildup from old engine oil, get your car serviced regularly. Make sure you follow the manufacturer’s recommended schedule for oil changes and other regular maintenance.

3. Prolonged Engine Detonation:

Engine detonation occurs when the fuel-air mixture in the engine combusts too quickly, leading to a knocking or rattling sound. This can cause serious damage to the engine if it goes untreated for too long. Engine detonation is typically caused by dirty fuel injectors, old spark plugs, or worn-out piston rings.

To fix this problem, start by cleaning the fuel injectors with special fuel additives. You should also check and replace spark plugs if necessary. Lastly, you can inspect the piston rings to make sure they are in good condition.

4. Worn Spark Plugs:

Spark plugs are responsible for providing the spark that ignites the fuel-air mixture in the engine. Over time, spark plugs can wear out and become less efficient at their job. This leads to a decrease in performance and fuel economy, as well as increased emissions of harmful gases.

To fix this problem, you will need to replace the spark plugs. This can be done by either a professional mechanic or by yourself, depending on your comfort level with automotive repair.

5. Can Be Noisy:

Petrol cars can be quite noisy, especially when compared to their diesel counterparts. This is due to the nature of the petrol engine, which requires a spark plug to ignite the fuel-air mixture. When this combustion process occurs, it produces a loud noise that can be heard from outside the vehicle.

To help reduce the amount of noise your petrol car produces, you should check the spark plug gap and ensure it is correctly set. Additionally, make sure that the engine mounts are secure and not worn out. If they are, then replacing them may help reduce the sound coming from your vehicle.

6. Oxygen Sensor Issues:

Oxygen sensors are responsible for measuring the oxygen content in emission gases produced by your car’s engine. If they become faulty, then the petrol mix may not be exactly right, leading to lower fuel economy and higher emissions. The check engine light will come on if the oxygen sensor is faulty and need to be replaced.

The best way to diagnose this problem is to check all of your vehicle’s oxygen sensors using a suitable diagnostic tool. Finding a replacement part is usually easy as they are common in most cars and a certified mechanic can usually handle the repair.

7. Burning Of Engine Oil:

Typically, for your petrol engine to run, it uses oil. But sometimes engine oil leaks through the seals or gaskets, which ends up burning in the combustion chamber. This is known as ‘high consumption’ and should not be ignored because it can lead to permanent damage.

You can find out if you are losing engine oil by checking the dipstick or looking for signs of smoke from the exhaust. To fix this, you will need to replace the faulty seals and gaskets, as well as get an oil change.
