I'm curious about the Oil change minder.

I've got an 08 LMM with just 60K. With an Edge EVO installed at 4K (Economy 1 setting), my oil change intervals have been;
4900 miles
12500 miles + new Fuel Filter
22300 miles
29500 miles + new Fuel Filter
40100 miles + Trans service
53500 miles + new Fuel Filter
58800 miles
Now with just 212 miles since the last LOF, I'm showing 87% left on an oil change and 79% left on the Fuel Filter.

What conditions does it register or monitor, for any change in Oil quality?

I'm guessing the programmer doesn't affect this, but haven't checked with them yet.

How consistent are oil change intervals with your LMM?

I don't see any patterns to the Oil change intervals with respect to my Towing, Highway driving, City Driving etc.

Whats your experience with Oil change intervals?

This is great question that I am also eager to hear about. It seems to me it is really based on mileage only and that it doesn't "monitor" anything at all since it seems to be very consistent with my truck regardless of winter/summer, or highway city miles.

It monitors RPM's, mileage, temps, and other things.

My stock rig goes 10K easy per the DIC, which is the max miles I am comfy with on an oil change anyway.

All bets are off with a tuner. I would go every 10K (or 1 year) no matter what your DIC is telling you. Fuel filters every 15K.
