I'm doing the suggested break in but it still makes me confused as to why I am not getting anything in my pipes. Is it the 94 Ultra burning that clean or should I have my car looked at by the dealer? I was thinking of using just 91 premium but I'm not sure if that is a good idea.Opinions would be appreciated. Thank you! Also found out that I can't get 94 Ultra in British Columbia so when I go to my vacation property am I going to upset the car by using 91 instead of 94?

Chevron in British Columbia has 94 octane at most stations. I run it exclusively in my ZL1. Im at 1000km and drive it hard at times and I dont get much carbon soot in the tail pipes either.
