I was having trouble editing my signature to update the mileage, but it is fixed now. I don't own a smart phone so I don't have apps to use with that type of reader.

Denso or NTK O2 sensor only please. These trucks don't play nice with other brands.

They should be shipped here today. I bought the more expensive ones before you posted and they are NTK. Thank you for the confirmation I bought the right brand.

Default mileage

2006 2500 long bed 4x4 with Jasper rebuilt hemi, 10 mpg without thinking about gas mileage, 9 mpg with 1500 lb camper on it. Oddly enough, when I'm crawling on BLM roads I still get almost 9 mpg.

Since my last post I am back to 10mpg and I am considering replacing the exhaust system along with the catalytic convertor.
Maybe this truck needs an enema.

Do you idle your truck a lot?
