[2008 titan se crew]

I have a 08 Titan CC with about 2000 miles, the other day I started to hear a knocking noise from the motor. It sounds like the lower end. Anyone else have this problem? It's not all the time. Any advice before calling the dealer

Don't use ARCO 87 octane gas. That stuff sucks a**.
Try using 91 octane see if that helps?

any luck on the knock?

did try using higher octane fuel. Have not heard it knock lately. I'm gonna let it go until the first service.
