Re: Regular Vs. Premium Fuel
Guy, you are absolutely correct- your Caddy requires premium fuel or it will knock. This article applies to the more modern technology of today's computer-driven cars and trucks.
I posted the article for information only- it is not my intention to encourage anyone to switch from premium to regular fuel: I was passing along information so y'all can make your own choice. I have used regular in my Crossfire without a problem and have been unable to tell the difference (other than in the pocket book) between it and premium.
I would imagine most will continue to run premium fuel but if someone decides to run regular in their crossfire (or most modern cars out there today) then it's nice to know that it can be done without risk or harm.
