Oil going somewhere?

[02GreyTahoe]

So, 2 months or so ago I bought my Tahoe. It runs good and is fine on both power and efficiency. However, earlier today my "check engine oil level" light came on. So I checked it, and it needed about a quart of oil. It never marks its spot, and it holds a constant 60 PSI. Anyone with experience have any suggestions as to what could be wrong with it, I.E. where the oil is going? It also doesn't blow blue smoke, aka burn oil. So this is quite the mystery to me. Also keep in mind I have driven about 3k miles, so it is time for an oil change. Any responses would be greatly appreciated!

mine does the same, it uses about a quart every 3-4 k miles. i've got 130,00 miles on my rig also

Did you change the oil in it when you first bought the truck 2 months ago? How many mls are on the truck? I ask because its not uncommon for these motors to burn a qt between oil changes. Now for the light to come on it would have to be lower then just a qt.

Ive had my light come on before and it does seem to burn @ quart between oil changes. I went crazy on this thing last year and replaced almost everything trying to get my mileage back up from 10mpg, I know everything is pretty new but it does burn some and there is no visible signs of it going anywhere. I have 130K on it now and it seems to be the nature of some of these things when they get up in mileage from what ive been reading

Not to thread jack,but your oil pressure is around 60? Mine is 40, is that bad? Mine also burns a quart and I have 145,000 miles on it.

I dont think 40 is a problem, mines about the same. My 5.3 burns oil almost as good as gas. Gotta keep an eye it when towing or sustained highway driving.
