In such cases, when you turn on the car, you will smell something fishy. It’s not just all about the tightness here. Many times, the gas cap gets scratched. In that case, some air is left within the tight spaces that could cause such an issue.

Therefore, next time, don’t forget to inspect the gas cap once you have refuelled your car. Because, on paper, it looks like a minor thing, but results can be expensive when it turns into such an issue.

2: Find out leaks

Let us be honest, what was the first thing that came to your mind when your car gave a smell like gas? Wasn’t it something about leakage? Most probably, it would be related to some kind of leakage. So, yes, leakages are the most common cause in this regard.

So, no matter the type of leakage, you should immediately take your car to the nearest dealership for a detailed check-up.

3: Spark plugs and injectors cleaning

Spark plugs are one essential component of your car’s engine. Therefore, they should be checked at every tune-up. If not, such issues can arrive. Basically, the purpose of spark plugs is to ignite the fuel and air mixture.

If they are old, loose, or unclean, they can be a cause of gas like smell that comes when you turn on the Ac.

So, check your spark plugs. If they are in bad condition, replace them with some new ones. Again, on every routine check-up of your vehicle don’t forget to check the spark plugs gap and its condition.

Furthermore, the injectors of your car’s engine can also be the culprit here. When they aren’t cleaned for long, they can emit toxic fumes resulting in a gas-like smell. So, also get them cleaned whenever you visit your local mechanic or dealership.

A fuel pump is one sensitive component of an automobile. Unfortunately, a lot of car owners don’t know the importance of this small component. So next time you experience a weird smell in your car, don’t forget to check your car’s fuel pump.

Replacing a fuel pump can be an expensive thing to deal with. Therefore, get your fuel pump inspected by a reliable car dealership. In most cases, simply replacing the fuel filter can also prolong the life of your car’s fuel pump.

5: Unclean air filter

How expensive is an air filter for a car? Probably some bucks. So, why don’t you replace at regular intervals? See, gas like smell can also arrive because of an unclean air filter. Here you have to understand the function of this filter.

As the name says, it filters the air that mixes with the fuel to form a mixture. This mixture is what your car engine runs on. Imagine how an unclean air filter could damage your engines life? So, try to replace it at regular intervals.
