Same filter on 3.0 and 6.6.
Of course 6.6 uses lots more fuel.

Recommended

• 22k max on 6.6, 30k max on 3.0
• 2 years max on either
• or if the fuel filter minder indicates change earlier

The only issue I had was resetting the countdown on the truck and I think it was because I was trying to do it with the truck running and it needs to be off.

Interesting that the owners manual doesn't indicate it needs to be off to get it to reset...
Just says' hold the thumbwheel for 2 seconds when fuel filter life remaining' is displayed.
