Nothing unusual for this fleet vehicle. I'd say around 6-7K miles for these engines is pretty good.

Only 7ppm iron and all other oil specs in grade/range… personally I’d be pushing it out farther. That engine is loafing along and loving life!

That 3.7L is one of the Cylclone engine series; very well performing for it's size and very easy on oil.
I'd say 10k miles is a reasonable step to make; the data supports that conclusion with low wear and low contamination.

Oil thickened out of grade very slightly.
.04 into the 30 wt range.

I'd agree. I'm considering revamping the service schedules to accommodate at least an 8K, if not 10K miles OCI for all of the 3.7Ls in my fleet. If I can nearly double the current interval, I'd be halving the average annual cost. Cost of an oil change is not really significant, but over the fleet it does add up and it's good to save money where practical.
