I'll update my mileage in July! I won't get the new 02 sensors installed for probably 2 weeks and then I will want to put several weeks of driving on the truck to measure the performance.

Again, calling my commute on a highway -- highway driving -- might be a stretch! Probably not different than any other metropolitan area.

 

Man your commute sounds like hell.
Mine is 16 miles each way, 12 of it is expressway and it takes me 20 min tops and thats at 65.
