Why does my car exhaust smell like paint thinner?

Over the last few weeks, I’ve noticed a weird smell coming from my car’s exhaust and I’m a little worried because I don’t know what it means. Why does my car exhaust smell like paint thinner?

Your car’s exhaust is a vital part of the vehicle running smoothly, so when you have strange smells coming from it, it’s always a cause for concern.
There are a number of reasons why you might be getting this paint thinner smell from your exhaust and the most likely is bad oxygen sensors.
If the oxygen sensors are the cause, you will probably notice some rough sounds or irregularities while you idle. This is because your oxygen sensors help monitor and control the air/fuel mixture that allows your car to run smoothly. When this sensor no longer works, the mixture of fuel and air becomes off balance and it will produce this paint thinner smell.
The best thing you can do about this problem is to take your car to a mechanic. They can properly assess the damage and get started on repairs.
