The newer GM vehicles have a feature built into the electronics, an algorithm that senses and calculates oil life. Some of the GM literature says it is not uncommon for a vehicle, under certain circumstances, to put as many as 15,000 miles on an oil change.
I'm not sure I trust the 15,000 miles but at the same time, I want to be as cost effective and enviroment friendly as possible. I put on a lot of highway miles and have been changing at around 6,000 miles.
I checked my oil life reading, using a Tech II and with 6,000 miles on the oil change, I show it still has a life of 47%.
Does anyone have any experience on the accuracy of this sensor?
I prefer not to get into a flame war over 3,000 mile oil changes, I am trying to gather info on the accuracy of GM's oil life sensor.
Thanks
