Impressive. See that’s why I don’t think something is right with my oil life monitor. I checked the oil. It looks good as you can see in the photo. I’m at 37% after 1749 miles and you were at nearly 7k! I do not do highway driving though.

If you can afford to just
"slap a new engine in it and go"
change your oil whenever you
"want to say I'm good".

If not, change your oil when your oil life monitor hits 33%. You do not do highway driving. Those are the best miles one can put on an engine.
Does your engine reach spec operating temp before you shut it down? That would also lower the miles between oil changes considerably.

If you turn on your engine cold, then shut it off before the temp needle points straight up, that might also make oil changes happen sooner.

I want to say run it because my job uses all third Gen Tahoes and suburbans for our shop trucks because we travel around the state and we sample grain from grain elevators and we’re partnered with BNSF railway and agtegra locations

Anyway, these are invincible you know we run the oil up to 10 K miles some times. Highway miles tho. And they’ll take the beating no issues and if anything happens, we just slap a new engine in it and go.


I want to say I’m good and it’s just due to the cold weather and idling and a lot of stop and go traffic because I do not travel outside of town at all guys.

The 2008 Burban is pushing over 300k at my job lol
With all the posts you've made regarding weird knocking and such coming from your motor, I would definitely be erroring on the side of caution when it comes to oil change intervals, but that is just me.

If you let carfax tell it I only change my oil every 10k since I only get the dealer to do every other change only because they rotate tires and check stuff I don’t. But I do it every 5k.

No it doesn’t reach temp half the time I have to drive to work a mile and shut it off and go into work and then repeat on way home. And it’s usually like below zero out. I try to run errands or take it on a nice drive if I can to let it warm up and breath all the way.

I’m just confused why my oil looks better than the actual oil life??

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's probably a good idea to make it a habit of changing the oil sooner on these vehicles to hopefully prevent sticky lifters
my recomendation is always 3k, not everyone agree's and that's fine.
I also drive my vehicle's pretty hard so I follow a extreme use interval, seems like the same would apply if the vehicle is not getting heated up properly and burning off condensation.
flip the oil cap over and if you see snot looking stuff inside that would be a indication of too much moisture in the oil.
