I used to have crickets noise, but it was gone after I filled up with Shell. Now, I am trying to bring back the crickets to show to the dealer for this TSB. Before using Shell, I used Chevron, and I had cricket all the time. Now, I'm on the 2nd tank of CHevron but still no crickets. I've tried to drive hard for 30 mins, and still no crickets. Has anyone experience that? May be the crickets are already gone. I don't know. I'm going to get a 3rd tank of Chevron to see what happens.
