| i found out that o2 sensors only have a life span of about 100km and then they should be replaced i was wondering if anybody out there with the 4.8 has replaced they're o2 sensors both upstream and downstream and noticed any mpg gains or overall improvement because i did it to my wifes car and got about 40-45km more per tank with no change in how it was driven or how much.I contacted my dealer and they said if it isn't showing a service engine light don't bother but it would only make sense that if you got a sensor that controls your air to fuel ratio and is exposed to dirty exhaust fumes and unburnt fuel it would only be a matter of time before they stop performing at they're optimum levels but may not set off the engine light what are your guy's thoughts out there? | |

Did anyone know that you can put your key in the igntion and turn the your silverado on, then turn it to the OFF position and hold the resest button for your odometer for 4 seconds and it will tell how many hours your trucks engine has been on!!!
