Oil Condition Sensor Question

[LZM3285]

2019 Ram 1500, 3.6L (23 mpg last 35K miles). I have read about oil condition sensor using an algorithm to tell how much use is left in my oil. My readout drops 1% for every 100 miles I drive exactly. Is it just a reminder or is there some science behind it?
Thanks.

That's a great question. I would also like to know if its sensor based information or just a simple algorithm.

I never look at the oil life indicator, always goes by the miles i drive.

I never go by the miles I drive, I go by the time since last oil change. And change it once per year since I only put about 8k miles on my truck per year.

I put around 18-19k miles a year so for me i need to watch for the mile.

Mine counts down exactly the same...1% for every hundred miles. I assumed it was simply a countdown timer and no oil quality sensors, etc are part of the system. I'd like to be wrong on this, but am I?

you are not wrong if everybody oil life indicator go down 1% for every 100 miles.

How many miles have you driven? What type of driving? My oil life indicator has appeared to be as you say with highway driving and has adjusted to around 7,000 miles if I continued to drive under the current conditions.

Oil change

I have 3,600 since last full synthetic on my 2019 longhorn. Dealer sticker said needs done in 200 miles. Oils gauge shows 50%

I'm honestly afraid to go with aftermarket oil filters while still under warranty, especially if I'm DIY myself. I don't want to give them any ammo in case there is an issue. Once my 5 year powertrain warranty wears out, I'm going aftermarket! As long as you keep the receipts to prove you...

2016 is not very accurate
