GT pinging on 87 octane
I'm getting some pinging (knock) under load using 87 octane gas from different premium brands. I switched over to 89 octane and the pinging went away. 1700 miles on the GT. I know that some pinging is normal according to Ford but the 89 octane does seem to solve the problem. Anyone else having this problem?
