OK really dumb but I want to know

Don't. Even though the engine has a pretty low CR, the low rpm low throttle timing is set to work with 91+ oct.

Buy one less coffee a week instead.

If a car is tuned for 93 octane or 91 octane I don't understand why anyone would risk putting in a lower grade of octane that could cause detonation? The price difference is not monumental and just seems like a suicide move IMHO. :shrug:

Because the 2.00 dollars they save at the pump is worth the same as 10K engine:shrug:...beats me.

I wouldn't recommend it, either. I could understand having to use a lower octane premium if you're traveling, but to purposely use regular gas, no. Not when the car is designed to run on premium. JMO.

The safe way to do it would be to get a new tune with timing lowered for 87oct.

Hell you can put diesel in it if you want, I just wouldn't recommend it.

So we shouldn't put diesel fuel in it????

Sure
Put in regular, after that, make sure you use the off brand recycled motor oil in your next oil change too.
