Mine has ate a qrt or more every 3-5k miles... So far Chevrolet has replaced all 16 lifters, added a "baffle" device in the oil pan and just this week, all 8 pistons and rings and performed a "decarbon" of the engine. This "oil consumption" is an issue that GM knows about well and have not figured out a way to completely stop it and it appearantly I have been told by a service advisor at GM that it happens to a few engine models but the AFM engines are the very noticable engines. For me I drive 52 miles a day to/from work in which most is interstate and it sees the "V4" mode a good bit. I am told that during the V4 mode is when the oil escapes and is sent as high as the intake manifold and then reinjested into the engine. I wish I had more good info on this as I would like to know the long term issues of having oil burned off through cylinders. Is this why I get 14-15 MPG using cruise at 65mph?

I have a 2004 Silverado 1500 (purchased used about a year ago with 74k) with the 5.3L V8 engine. I now have 86,xxx miles on it and have changed the oil & filter four times now - once every 3,000 miles or so - since I have had the truck. I always use Mobil-1 5w30 synthetic.

I find that the truck seems to use about 1/2 a quart (more or less) between changes, which I believe is on par with just about every vehicle I have driven. My driving is about 60 percent highway/40 percent city; and I average 16 mpg or so (14 city and 19 on the highway).

Even when I change the oil, it is obvious that my truck could go with longer intervals - but to me it is "cheap insurance" to change the oil and filter more often than necessary. Oil is the lifeblood of an engine, so why take chances or cut corners?

With a 3k oci why not just stick with conventional oil and save some cash?

At the risk of starting a major battle here goes. I do not subscribe to the long oil change intervals. Nor do I rely on oil life monitors. If you will notice when the milage reaches about 3K miles is when the level starts to drop. This tells me the oil is breaking down. Your type of driving has an effect on this also. I change my oil and filter at 3k and have never had to open up an engine in the last 40 years. I usually run them 150-200k. Yes I know there are exceptions,but on the whole you are going to spend your money on oil or engines,your choice. And it not a bad idea while the tank is filling up to pop the hood and check the oil.

My 07 does the same thing. So far the truck has been through the "decarbon " process and has had the baffle in the oil pan installed. Still using oil though!

This is new to me. I have never had a Chevrolet that did not need overhauling use that much oil. Fords blow through 5-20 like crazy, but I have never had this problem with Chevrolets. My 2011 1500 is too young for me to know yet what it does, but my 2003 6.0 in my 2500HD uses less than 1 qt per 15,000 miles. When I change the filter at 7500, It takes about 3/4 quart to fill engine and new filter. When I do my final drain, at 15,000 it is about 1/2 qt. low. Yes, extended performance mobil is holding up that long according to oil analysis.
My 08 Cobalt uses less less than a pint n 15,000 miles.

You hot shot with a little 5.3 what are you pulling cotton *****. jk.

My 07 6.0 with afm uses less than .5 qts between oil changes. I drive in very heavy traffic and mayby twice a month get to run it on the interstate. The 2 oil changes Iv had since I got it used at 32000 miles have been done at the dealer free of charge so I bet they are using dino oil. I did the first at 3k then the second at about 8k when the indicator came on. I think any more than about a qt per 3k is way to much but what do I know Im just a IH, KW, Cummins, and Cat tech. (yes i know there are differences in a gas burner and a oil burner)

Has anyone else experienced having to take their vehicle into the dealership 4 times for a low oil light. We have taken our 2007 Chevy Silverado LT crew cab with 5.3 engine. into the dealership, which they have changed the oil two times, done two cleaning kits for the pistons & rings, replaced the lifters, done something with the oil pan,now they are replacing the pistons and rings. It only has 40,000 miles on the truck. Was there ever any recalls on these engines?

I had all the same work done to mine and it is still eating oil... I am a little over 80k miles and have been told even though my warranty is good for another 20 I will never see a new engine... Nice huh? Now I have shifting problems in conjunction with a "Service Stabilitrak message"
