Low octane is fine on the Original car and you can burn higher..depends on what you've done to the engine. Also, use copper spark plugs not the 4 plat.

For CA smog tests burn low octane; you get a most complete burn due to the flash point. It will help keep the HC's lower on the tests, particularly if you have higher mileage.
