C6ULATR

Just trying to find out if anyone has had issues with pinging when accelerating. I live in California and can only find 91 octane gas (Union 76 or Mobil is what I use). I'm thinking that I probably need to add an octane booster to my fill-ups. I only seem to notice this when I jump on it. Tried to find this on a search with no luck, so I apologize if this is a dupe question.

Thanks,

PvK

On page 5-5, the owner's manual says 91 octane should be okay. They talk about getting a heavy knocking noise if you use octane 87.

I haven't used anything less than 92 in 7 years the few dollars more per fill up to me is well worth it.

The highest octane I can find in So Cal so far has been 91. I had heard that it has something to do with the friggin pollution / emission requirements established for California.

I live at 4500 feet, mine wouldn't ping with 87.

Just exactly what is the highest octane rated gasoline available to the public anyway.

93 is the highest I've seen in mid-TN.

Where do you find the IP for the car?
