That's all I run all the time. From what I've been told it's motor octane is close to 118...I am not sure though...it's 100 for sure though. LL stands for low lead. Don't want to run cats w/ it. It costs half as much as race pump gas so it's realistic to run it all the time. For me it's the pump because I have the hook up to actually pull the car up to the pump at the airport!
