Same here, my Graphite had 116,000 on it; I can't say it did not use a "drop" of oil, but it sure never used more than 1/4 cup, if that, in the 5000 to 5500 miles I drove it between changes.

If you wish to stop doing oil changes, switch to propane fuel. Changing the filter does NOT mean you have eliminated contamination.

Gotta tell ya, cjfine, I thought you were trolling here. If you have done any reading at all, how could you miss the fact that engine oil becomes contaminated. "Breakdown" of the oil is not the entire reason to change it.
