Damn, my age is showing. I had to Google "RTFM"You should RTFM. My '19 GT manual states that the car is made to run on 87. For best performance, use 91 or higher. Where you get the temp bit I don't know because it is NOT in my manual.
This coming from a guy who adamantly uses Shell 93 Nitro and nothing else, period. 87 is just fine. I use 93 for the extra cleaning detergents, not for horsepower. BrieBee72 is correct that all top tier gas gets the same detergents. However, premium grade gets more than 87 or 89.
You can run a GT on 87 pump all day, every day, with no issues. If you don't believe that, then you are in disagreement with the people who built the car.
