My Low Oil Pressure Story ----
Two days ago in the Am I started up and had driven about 3 miles on city streets when the LOW OIL PRESSURE SHUT OFF ENGINE warning appeared. I was stunned. I pulled to the curb immediately. No noises of any kind.
The reading was around 10psi bouncing a little to say, 30psi. I checked the oil level, it looked 1 qt down. Of course, I always carry oil. I put one in. Retested. It came up to 50psi which is normal, so I pulled away from the curb but in 2 blocks it went back to zero and the warning was back.
I found a level parking lot right there and pulled in to level the car. Checked the oil again, and it was 1 down again. I figured it must be pouring out somewhere. Looked high and low in and around and under engine. Nope. Not a spot of oil anywhere - no smells. I shut the car off, added one more quart. Sat thinking for 10 minutes.
Started, and it came up to about 30psi. I made a few circles are the level parking lot. It wouldn't come up to the normal 50. But it didn't go below about 25. So I went ahead and drove to work 3 miles away. It was bouncing around between 20 and 40. It never does that.
Came out from work 4 hours later and it was at solid 50psi - normal. It hasn't moved off that since Monday.
Q: Is the sensor/screen affair easy to pull? (I am only "fair" with tools). Or is this something for a pro?
I will get my oil changed as the life is on 15% anyway. I guess this is a common problem?

Not sure why where you buy the filter would have anything to do with the quality of them. Searched internet for Fram filter problems and did it for other brands, seems you can find anything you want. I did come across this filter test and basically the Fram came out on top and the AC Delco was near bottom. Oil Filter Comparison Study - GM Truck Central
Thus, I'm not sure who you can believe/trust. I guess the only true result is buying the filter from the GM dealer where hopefully they are buying them from GM and not through some off distributor. But with my experience with GM dealers I would not put it past some of them.
Anyway, no more problems since changed filter and oil. I will change filter more regularly to avoid anymore possible problems. Forum was great as it helped me trouble shoot the problem to a resolution I am happy with. Thanks everyone.

Its not so much were you buy it but the type of store selling it... I said Lowe's because they are not in the Auto parts business, so if they are selling Auto oil filters its because they bought it cheap enough to make a decent profit on it when they sell it...
They could sell other filters but some of those filters cost more to make therefore reducing the amount of profit that can be made off it to still sell it competitively..
I prefer to use the AC because its OEM, GM wouldn't use something that is knowingly going to cost them money for warranty work...
Amazon carries the AC filter, along with many others. They can be ordered in bulk and be delivered right to your front door , thus removing the dealership or a long drive to the Auto parts store if that is the case...
Fram may have a good product, but they have had there share of bad reviews, enough so that I won't risk using them...

I too have a 2007 Suburban and it is my wifes daily driver. Today she had the low oil pressure scenario happen to her just as has been described throughout this thread. I hate to say it but I think I hear some valves rattling when I start the engine. Granted, it is not my daily driver so I cannot pretend to know all of its sounds. Right now I guess I just have to hope for the best and get it into our local dealership where we bought it.
Just a general question; Do all Suburbans seem to use oil to the point of needing to add a quart now and then even between oil changes?

Our '07 LT's valves clattered for 30 seconds or so from start-up. Clattering went away after it warmed. It did this from the day it was new. I wasn't comfortable with the dealer's explanation of "some do this, and it's nothing to worry about." Oil consumption for this Suburban was negligible.
When we traded in the '07 for an '08 LTZ (leased), the engine never clattered. However after 40k on the clock, it started to consume oil to the tune of 1 quart every 3k miles, then seemed to plateau out at a quart every 2,500 miles. No leaks, no blue smoke, no smell, no clatter.
Again, I was uncomfortable with the character of this engine so we didn't buy it after the lease was up.
We went back to an '07 LTZ. No clatter, but similar oil consumption as with the '08.
I'm sure you can find numerous discussions about mystery oil consumption w/Suburban & Tahoes. I believe that oil consumption, valve clatter and low pressure as a result of a clogged filter are all completely isolated from one another....at least in the case of our Suburbans.
I've decided that I'm going to live with the oil consumption phenom, and I carry a funnel, a pair of latex gloves and a few spare quarts around in the bin.
My wife now knows how to add oil in the dark.

On my 07 I've never had a oil consumption issue, though on a cold morning after the truck has been sitting for a couple of days I get just a tiny bit of clatter that quickly goes away as the oil starts to flow... I suspect its more so due to sitting for extended time and oil being thicker when its cold out...

We had to have a new sending unit installed and it appears to be fixed! We love our Suburban and feel very fortunate that this was all that had to be done. As for the noise I was hearing apparently one of the pulleys was loose and we had all the belts replaced too. Seems like a new running vehicle again.
