Re: 19.8mpg after HC removed!
I have placed this info on other sites, here goes.
I have a 2008 DC 5.7 4x4 with 15000 miles and a bed cap. I removed the HC charcoal filter.
After an 820 mile trip on paper I got 21mpg.
I use the manual shift a lot but the AI kicks in when taking off from a stop.
I love this truck and when Obama is voted out gas prices may come down even more.
