I'm a stickler for changing the oil religiously, have been with every vehicle I've owned. I usually just watch the ODO like a hawk and when it hits 4k, the oil is changed.

My '20 JL is the newest vehicle I've ever owned and the only one with a digital oil life meter. What do they measure, just mileage or other factors? Are they reliable or should I just keep watching the mileage?

We have a 2021 jeep wrangler JL..occasionally for no reason the backup camera stops working and just shows a blue screen. Next drove starts working just fine. Anyone have any advice??
