I wouldn't. A cleaner-burning fuel is better for the life of your engine, and with as much as we paid why cheap out on gas..
BUT it is good to know that in a pinch if you had to put 87 in your tank you can do so without your car throwing up.
I researched the hell outta this car before I traded in my 16 GT Performance Package for it. I'm an engineer myself, so everything I researched about this thing amazed me. It really is a one of kind, amazing piece of engineering. Can a 2019 GT out drag this car? Probably. But that is not what this car is about. It's a track car. I can pull a 2:42 around Sebring, without even trying, and without using any other gears than 3 and 4, and I STILL have room to grow. That's what I love about this car.
