Hi a couple questions , but first my thoughts and prayers got to both Mr Jensen and especially Mrs Jensen .
1st question, In the pictures above I'm sure you stopped at Shell for a reason , as I fill up at Shell . I herd Shell is the best of all the upper petroleum brands
2nd Q , is Race Fuel Consentrate safe to use,( spark plugs , emissions system fouling) I have a stock ZL1 , and maybe don't need to consern myself with running an additive . The best pump premium available here in Arizona is 91 octane, and with the heat should I ? Thank you
