I use 93+ (SI Tune for 94)...

Sure the car can run at lower Octane levels, but why would you want to?

I reviewed this car for what it was; before I purchased it, I test drove it, fully inspected it, reviewed at the MPG, and knew exactly what Octane level the manufacturer suggested, and after careful consideration I bought it!

After that, all hope of returning to a normal conventional world just seemed to fade away!
