hi, would like to know that since it states to use premium gas on my car, and with gas prices skyrocketing, can i use regular unleaded or will it damage anything in my car. help soon. my pockets are burning a hole.

You can run lower octane fuel at the risk of degrading the performance. I recommend following the car makers recommendation for fuel.
