06' just hit 33,000. Sat all winter, oil changed a few weeks ago. Noticed a ping, chirp, sound, etc? from engine while on recent trip. All gauges were good and ran strong. Put some 93 octane in. Will see what happens.
Nothing. Adding 93 octane won't do a thing except cost you extra money.
Not true if it is a pre-ignition ping.
I always run premium in my 4.6L E150 when going through the Smokey mountains, towing or not.
