Moved from the break in thread. kw
One other thing - although not exactly on topic on this thread - I now endorse the use of the oil life monitor in the Avalanche (duck!). I use to be of the change the oil every 3K like religion but over 46K miles this is what I've observed (and as a disclaimer I did oil changes at 1K, 3K, and 6K to Mobil1 and THEN followed the monitor).
When I was doing a lot of city driving commuting to work in downtown Seattle I found that the light would recommend changing oil from 4.2 to 4.6K.
When I went on several hardcore off-roading trips over a two month period the light came on after 3.4K miles. So to me it sure did seem like it was looking at load.
When I altered my driving habits and it became more long distance on the highway at cruise in the HOV - the light on my last go around did not come on until 6.8K miles.
It appears to me after a variety of driving that the system does "work" and I'm happy with the recommendations from the computer.
As I said - duck!
