If your car is stock then 87 octane should be fine. If you hear pinging go up to the next grade. Premium fuel burns slower so it will actually hurt performance if you do not have a supercharger or a chip that makes use of the higher octane. Plus it is a waste of money.
Gas companies have been claiming for years that higher octane fuels burn cleaner but the exact opposite is true. Lower octane fuel burns cleaner and all grades of gas have the same amount of detergents to keep your engine clean. Recently the government declared that gas companies can no longer claim that one grade of fuel is cleaner than another because it is a boldface lie. Use what the manufacturer requires for best performance.

You shouldn't have any pinging. You number is high enough that you have the KSG 02 version of the computer program which was supposedly the reason Ford changed from KSG 01 to 02 around No. 2500.
Stick with 87 unless you get a chip. The current programs run rich anyway, and higher octane ratings only make that worse.

The main thing a chip does to improve performance is bump the timing up. When you do this you have to increase the octane to eliminate detonation (pinging). I currently have to run 95 octane in mine with the supercharger until Vortech can get acceptable degree of timing programed in that will allow me to use the crappy 91 octane we Californians are stuck with.

That is correct.

I have the 02 flash, and I get ping at WOT on 87, so I use 89. I keep decidi g to try 87 again, so I get a tank, it pings, and I go back to 89.

Had the same thing Joe with 1302.....had the reflash and was still pining with 87. Since I was running prem I went ahead and took full advantage of it and installed a SuperChip. No complaints.

I switched to 93 octane thinking it would be better, but noticed when I got on my car, I got a real bad sulfur odor emitting from the exhaust. So I tried a different brand of fuel, but still got the same odor. Changed to 89 octane and that corrected the odor problem. Since the high octane fuel doesn’t burn as fast, it was causing the problem. Hope that helps.
Some wont agree,but I would base what octane of fuel to use in YOUR car based on what fuel it requires for best performance.My car seems to run better on premium fuel than regular unleaded,and it is KSG2.All things are not equal,yours may be different!
