My daughter recently purchased new a 2024 Honda CRV with a turbo engine. It currently has 6,200 miles on the factory oil. The OLM is showing 50%. Pulling the dipstick the oil is pretty nasty looking and nothing to be proud of.

I cannot imagine that the car could go almost 12K before needing an OC. I also think there are many variables that the monitor cannot take into account such as winter driving and fuel dilution.

I told her to go to a 5K oil change. She is getting that done tomorrow.

What do you say? Is the monitor a true guage of oil quality? Am I jumping to the wrong conclusions?
 
I think you’re right. 5k oil changes is what I would do on it. 6200 on factory fill and it’s still showing 50%? There’s no way that’s accurate IMO.
 
Some IOMS have shown to be very good, when compared to UOA.
Others have shown to be a poor indication of lube health.

The only way to know if it's trustworthy is to run several UOAs against the IOLM and see how "good" it is at predicting the oil condition.
 
My Honda v6 oil life monitor only moves in 10% increments above 15% so yours might actually be at 41% about to go to 40 in another 10 mi. I have to let my OLM run to completion so that it will output the codes for other services due, but like you my eyeball OLM thinks the oil is getting pretty dark by 5 or 6 k and I change it then. Somewhere around 9k is where the official monitor goes to 15% and puts out a message that oil change needed soon.
 
An OLM won't be perfect, but it'll be more accurate than using mileage alone. I'd base it on the OLM, but change it at 40-50% if you want to be conservative.
 
What OCI does the owner's manual recommend? Do they specify an OCI if the car has OLM?
I never owned a car with an OLM. Only have the sticker that the dealer puts on the windshield. 🤣

5K Miles with a thicker oil sounds good having a small turbo & black oil.

Both of my cars have oil life monitors and neither of them specify an OCI. They both say to use the OLM for oil change frequency
 
In 2014 K24 engines, the Honda OLM worked fine...over 128,000 miles on ours...replaced the Valve Cover gasket at 120,000-something and the valvetrain looked great (photo has been shared several times on this site...don't want to take up any more server space posting it again). Don't know about the 1.5 Turbo OLM.
 
Honda specifically says not to do the first oil change early and to leave the factory fill in until it says 15% or one year. Honda uses a special break-in moly additive unavailable commercially.

After dumping the factory fill, using 5w30 will help. Many people with those turbos also get better results by filling up with premium.

While the minder might miss the fuel dilution, winter driving absolutely can be taken into account. Low ambient temperatures, idling (like you do while warming up the car and cleaning off the snow), etc.
 
My Titan just has a maintenance reminder that is factory default set for 5k . I think you can change the set point but I like it at 5k .

Change the oil as often as you like, just don’t reset the monitor until 15% or lower. That way the other maintenance algorithms aren’t affected.
