Ive been doing a little looking for a road course to run my svt on. and it looks like the closest one is mid america motorplex in pacific junction, ia. looks great, 2.23 mile 15 turn course, i cant wait to go. it says they offer 94 unleaded, 110 unleaded, and 110 leaded gas on site you can fill with. my question is would it be a bad idea to use the 110 unleaded in my car? ive heard of people using higher octane in there cars that take premium and it makes a HUGE difference. im just not wanting to hurt my car as its my daily driver. also if anyone knows of any other road courses in or close to iowa, that would be great. thanks!
