Please explain what point you are trying to make?

If you go by the indicator only and don't drive much you will surpass the 6 month time limit. The indicator doesn't account for time other than engine hours.
Don't gave Ram any excuse to denie warranty because you changed it based on the in dash indicator.

I noticed that clause in the manual too. I did my first change just under 5k miles (8k kms) and I forget exactly what the monitor said but I believe it was still almost 70%. This mileage was what I was at right around the 6 month mark of ownership so I figured it was time given that it was still the original factory fill.

As a side note, make sure you are prepared either to disassemble the air ducting above the oil filter or have a large ziplock bag ready to drop the old oil filter into before performing an oil change. These trucks are really beefy and access to the oil filter is very limited! I am also going to have the Glad press and seal ready to go on the new oil filter seal so that it can be prefilled with oil before having to turn it on it's side to get it between the frame rail and wheel liner.
