5.3 V8 oil consumption

My 2007 TB 4WD w/ 5.3V8 is using a quart of oil to 2500miles. It has only 46,000 miles on it. I purchased it as a lease return with 27,000 miles from my local Chevy dealer with warranties. The car came from Michigan. My dearleship is doing an "oil study" on it. Dealership states oil consumption must at least a quart to 2000 miles for Chevy to make warranty repairs. What is the experience with oil consumption on the 5.3 V8? My build sheet lists the 5.3 as an option LH6 vortec V8 with active fuel management. Is this engine considered to be in the LS families or is it something from preveious designs? I would really like a 6.0L engine in it. Thanks for your help.

All of the 5.3's DO burn oil. I'm not sure on the rate, but a quart to 2,500 miles does sound a little on the high side.

I do believe there is a TSB on this issue. Search for it.. I think it it has to do with either the valve covers or the baffles.

Not all 5.3 engines burn oil. My 2004 Rainier has 105,000 miles on it, and the oil level is always near the full mark on the dipstick before I change oil and filter whenever the Driver Information Center tells me to do so. That's usually at about 7,000-mile intervals. If I had to guess, I'd say that my Rainier uses about 1/4 quart of oil between changes.

I do my own changes and always use Mobil 1 5w30 synthetic oil with an AC Delco filter. I use the same Mobil 1 5w30 in my 900-horsepower Camaro 1/4-mile drag-race car and have always been amazed by the absence of wear on internal engine components during the engine's annual tear-down.

My Tahoe had a cracked intake manifold and used oil like that. It seems to be a GM problem as I have friends that are having the same problem.

My TB EXT with the 5.3 also uses what I would consider a lot of oil. I have to put a quart in about every 2500-3000 miles. No other adverse effects, you cannot see burning oil, you cannot see anything leaking. It just burns it slowly and has since we got it. My 99 Silverado Z71, same drive train, did exactly the same thing. I had a Camaro with the LS1 in it and it also used about that much oil. All from new or nearly new. Dealer said its normal.

So I think it is more common than not. A buddy told me that conventional motor oil would help, but I tried it and it did not help any at all. So I switched back to synthetic.

oil comsumption

I have a 2006 Envoy Denali that was using 1qt every 1500 miles. Lucky for me it was a GMC Certified vehicle with the 100k mile warranty. To make a very long story short ~ the 1st dealership I went to did absolutely nothing, and made it clear they had no interest in looking at the vehicle. 2nd dealership went out of their way to make it right and fix it. Step 1 was to try changing valvle cover, as I guess the newer 5.3 had the PCV valve located underneath the inside of the valve cover. Wel that didnt solve the issue, so they went to Step 2. They changed out all internal engine components (lifters, pistons, rods, bearings, crank shaft) and so far so good. Ive driven 2k miles and it hasnt used a drop of oil.

I am also currently doing a consumption test on my 5.3 they have said a quart every 2000 miles is normal but my difference I notice is when it turn it's self into 4 cyl mode for 5-10 mins and than switches out a big cloud of smoke comes out the back if I find out from the dealer that it needs fixing I will be sure to let you guys know what they said

I learned a lot about the 2 different dealerships I went to about this problem in the first 5 minutes of talking to them. A lot of these service managers assume that every customer is an idiot. Well there is this thing called the internet that enables customers to educate themselves prior to contacting them, which I did.
The 1st dealership acted like they NEVER heard of such a problem with these vehicles, and proceeded to hand me excuse after excuse as to why I was just s-o-l. I told them I will take my business elsewhere and will be sure to tell everyone about their lack of customer service. 2nd dealership right away said they knew what to do regarding the problem and would get it fixed, and gave me a loaner car in the process. Top notch compared to the other a$$holes. Good Luck!
