Most flex-fuel vehicles have a fuel cap that is specifically marked with the letters "E85."
If your fuel cap does not have this marking, your car is not compatible with E85 gas.
2. Check your owner's manual.
Your car's owner's manual will also specify whether your car is compatible with E85 gas.
3. Do a VIN check.
You can also check your car's compatibility with E85 gas by performing a VIN check. This can be done online or at a local dealership.
4. Ask your dealer.
If you are still not sure whether your car can handle E85 gas, you can contact your car dealer. They will be able to tell you for sure.
Here are some additional things to keep in mind if you are considering using E85 gas in your car:
* E85 gas contains less energy than gasoline, so your car will get fewer miles per gallon (mpg) when using E85.
* E85 gas can be more corrosive to fuel system components than gasoline, so it is important to keep up with maintenance on your car.
* E85 gas may void your car's warranty, so it is important to check with your dealer before using it.
Overall, E85 gas can be a cheaper and more environmentally friendly alternative to gasoline, but it is important to do your research and make sure that your car is compatible with E85 before using it.
