Dealers dont know dick but anyways I have always run Shell or BP gas in my 05 FX4 and always use the best. 93 octane is the way to go. You only spend a dollar extra every ten gallons. People make it seem like thats ridiculous. Just pony up the extra cash and put the good **** in. You get out of it what you put into it

Sounds like you may be talking about a knocky rattle that only happens at low rpms if you give it gas. Mine has done this since new. To me it sounds like knocking from bad gas. The only way I've been able to prevent this is to use 93 octane which is ridiculous. It completely goes away with 93 and comes back with anything less. The truck is designed for 89 octane. I've asked the dealer several times, but they just say that it's normal, or tell me to try different brands of gasoline, yadda, yadda.

Yor truck would do fine with 87 octane. Using a higher octane does no help your truck- actually it hurts you fuel milage bacause the higher the octane the more resistant the fuel is to igniting. The higher octane fuels are mad for vehicles with high compression engines ie: Corvette. You are just wasting your money.

I'll see if I can't get a sound clip of this noise up. It does it at idle up to parking lot speeds.. Hell it might do it all the time and you just can't hear it over normal engine noise at some point. But it's loud enough in a parking lot with the windows up and radio off that you can hear it ticking away. Only when it has been at operating temp for a little bit though.

OK, got some sound files done.
First one is normal, you can hear some injector tick but nothing major.
Second one, aptly named, you can hear a much deeper tick/knock. It's most pronounced towards the end of the file.

engine warm deep tick.mp3

How about posting links to file we can all access without giving us a file denied access error??

mine tick like mad on my 4.6 3v, and mine has less than 6k on it
only does it if I get on the gas a little harder than normal when at a low RPM
as long as they don't get horribly worse, I'm going to deal with it. if they last until the warranty is up, then I plan on installing some FRPP Hot Rod Cams, and I'll be installing the cam phasor lock-outs at the same time
