Not sure why the text didn’t upload but:

Oil life seems a bit low for only 1749 miles since last change. (2014 Tahoe)

Changed it at 168,832 miles. 2014 Tahoe 5.3 v8 doesn’t burn or leak oil. I can’t recall oil I used but iit was a decent synthetic brand and I used the right weight and all that. Added the right amount etc. typical oil change. Not to hard can’t really mess it up.

Anyways: for in town driving would this much oil life be acceptable for 1749 miles? I don’t ever travel. Just driving to work and stuff like that. And sometimes I let it idle for a bit to warm up. Maybe 5-10 min. My oil PSI is good too. And inspection on it recently

It used 63% that quickly? When do you normally change the oil? By the monitor (if so what %), or by mileage?

Is it possible the monitor didn't reset and now you are just seeing lower than before? I usually change mine at 5k, which is somewhere around the 40-50% oil life left per the truck. I occasionally forget to reset it, but don't really use it other than a check point.

If you did reset it, then my assumption is that lots of short trips with idle time in cold weather could cause that. There are all kinds of inputs that go into the calculation. The oil looks decent from what I can see.

@iboughtatahoe23 That "oil life monitor" is just a timer, it doesn't actually mean anything.

As long as you can see your dipstick through the oil you are good, if the oil is so dark on the dipsticks that you can't see it then its time to replace it.

+1. I find that oil change shops seldom reset the oil life minder.

My solution is to change the oil every 5K miles at 100K, 105K, 110K, 115K, etc so it's easy to remember.

I did reset the oil life gauge bc it was at 40% when I changed it last in August and there’s no way it used only 3% in 5-6 months.

Mileage is 170 K and it’s only been five months since I changed the oil and I’ve only put on less than 2K miles. Only factors I can think of is cold weather in the last few months, idling, high miles. Idk.

I changed it at 40% life last time to.

I bought it at 165k in February 23’ had fresh oil done that following march and changed again for 2nd time this last august at 168832 from 165k miles the first time and this time around I have oil life at 37% now in January and only have 1700 miles on the second oil change

Yes to answer your question I do do a lot of short trips and idling and it is really cold here about 20° on average and been dipping below freezing lately. But my oil doesn’t look like 37% oil life?
