Human: Is there any way to tell if my car is leaking gas? Assistant: 
There are a few different ways to check for gas leaks. One method is to look for bubbles or smoke coming from the engine compartment, which can indicate a gas leak. You could also use a fuel pressure gauge to measure the amount of pressure in your tank and compare it to manufacturer specifications. Finally, you can take a sample of the fuel and test it with an oxygen analyzer to determine its purity.
