If its a newer car you dont need anything more then unleaded...
93 is for cars like my 71 mustang which will ping and detonate if run at a lower octane... Now the newer cars...
I run an 04 mazda3 with full headers, straight exhaust, intake, computer work, and too much to list... I've taken apart 4 cyl engine blocks... some places you get gas from is just shitty. Cheveron Silver is good, clear as water. Mobile is good too.

Your point?
I have a 71 mustang in which I squeezed a 460 big block into...
Custom everything...
469 horses... 600lbs of torque.... I built that engine in my fucking kitchen.... I polished the rods while watching tv on my couch...

Did you change the compression on the engine by changing out anything internal?
