California smog!!!!
My smog is due again on my 85 Carrera . I usually do all the required things before the test but I can't remember....Is it best to use 87 rated gas for the test over 91? Also, I put Valvoline 20/50 racing in my car but would there be a better temp oil to put in just for the test? Thank you. I hate test time!!!
