I've never used anything other then 93. When I can't afford the gas or worry about the difference between the price of 87 and 93 in a full tank of gas. It's time to get rid of the Vette

That's the highest I see in my area. One time I accidentaly put 87 in it, I had just filled up a car I had sold(I work at a car dealership), and my mind was just in the 87 octane mode. I didn't realize til it was half full, and it didn't like the lower octane. My car was tuned with 91, so that's what I put in it.

Octane Octaves
I have run both and as long as I was a good boy, I could get away with it. I don't drive mine that much as it is not my "Daily Driver" so I always keep it filled with Supreme. Let's take a look at the Mathematics here:given that Regular is $2.99 per gallon and Supreme is $3.19 per gallon. I just fueled up this morning in Carlsbad, California and used 15 gallons.
15 gals. X $2.99= $44.85 for Regular gasoline
15 gals. X $3.19= $47.85 for Supreme gasoline
Regular Gasoline= Driving Miss Daisy
Supreme Gasoline= accelerating and driving with reckless abandon
If my calculations are correct the difference in price is .20 cents per gallon and I used 15 gallons.
15 gals. X .20 cents= $3.00 more money? I guess it really depends on how many times a week you are filling up. At roughly $3.00 per tank I probably won't fill up again for another week at least. Somebody else check my math as I am a tired old man! I might just stand corrected so be kind!

If you run it hard you should definitely use Supreme. If you behave yourself and drive it very kindly and stay out of it, then you can probably get away with Regular Gas. "probably", if you hear pinging then you are into it too much and you had better step up to Supreme. I have run both and as long as I was a good boy, I could get away with it.

As far as your question - how low you can go before it starts to ping - I think the computer compensates for the cheap, low octane gas and you won't hear a ping.
So, just keep running the cheapest, lowest octane gas you can get and when your engine stops running you know you've hit bottom!
