So my 2013 Infiniti G37 requires premium gas (91 octane) but I just got it so I didn’t know, and I accidentally put regular gas (87 octane) into the car.
I filled my tank almost fully with regular gas. I have only done this once since I just got it, and I plan on using premium gas in the future.
I am not an expert in cars, but I am worried that my car might be permanently damaged from this. Is this true or do I not have to worry if I only do this once?
