Add a quart or let it ride another two weeks?

I got about 187K miles on my 2014 Tahoe due for an oil change in about 600 miles. I’m thinking I’m a little bit low here. What do you guys think? This was after driving around and than letting it sit for abiut a hour.

As I understand it, each hole on the dipstick represents 1/4 quart of oil. With that understanding, you have very little appreciable oil loss.

I’m not a mechanic by any means just a guy that likes to DIY and tanker but is this a pretty good sign for our engine with high miles?

On the other hand, the full mark is where it is for a reason.

Leave it

As long as it's in the hatched area it's fine.

If it was bothering me, I'd just change it 2 weeks early. Why wait 2 weeks?

Could throw a cleaning agent in there for the last few remaining miles, it could probably use it at 190k.

This, anywhere in the middle of that hatched area is fine if not perfect. When/if any of my vehicles get close to the bottom of hatched area and im not due for an oil change yet i just top it off with whatever i have around the garage.
Anywhere in the hatched area is fine tho.

Yes, it truly is only a little bit, about 1/4 quart. This definitely doesn't justify another whole quart.

What you left out of "in about 600 miles" is what interval you are using, so we have no idea what the rate of consumption is. For sake of easy math (and in no way suggesting this is any actual interval), if you were using an interval of 1,600 miles, that would mean the engine is only consuming 1/4 quart per 1,000 miles. In that case, your engine wouldn't consume enough in 600 miles to get down to the second dot. You don't need to add any.

Also, I would not add any "cleaning agent." Your oil isn't very dark, modern oil technology doesn't need it, and you can screw up the oil chemistry.
