My Truck is burning 2L of oil every 5000kms up here in Canada and I've been told by 2 dealerships that anything less than 1L/1000kms will not be addressed by GM and will be considered "normal".

 

Do they realize that if that little nugget of info were to get out into the mainstream their sales would go down by 50%?

 

"Buy our vehicles, topping up your oil twice between 5000km interval oil changes is "normal"." Geez, such a disappointment.

 

Anyone else getting the same runaround?

I've been watching this oil usage issue a long time now. Sick of it. My '96 5.7 used NO oil! And I could get 20 mpg highway. Extended cab, loooong bed too. Dagnabbit, GM is running customers away.

Yep - they've forced alot of manufacturers to cut corners just to survive.   The EPA has done more harm to this nation the past 20 years than good. Another gigantic, bloated, goverment bureaucracy t

It is a sad testament to GM quality. My factory remanned 12.7L Detroit, 704,000 miles into its second life, only uses about 1 qt per 10,000 miles. Just did oil change on it at 21,580 miles on the oi

I would say..Find another dealer...They are all different in how they handle warranty issues....My dealer has been fantastic and has addressed my problems without any grief.

Mine has been burning oil at about the same rate as yours. It started at about 100,000km and I'm just over 200,000. I've mentioned it to the dealer here numerous times and they monitered it but never took action to do anything about it. Now the dealer is closed and I started to go to another dealer and I got told some oil consumption is normal but they wouldn't disclose at what rate. I've tried different oils giving each 2 or 3 oil changes but nothing changes. Always keep an extra litre available in the truck for when the light turns on.

As note I have just shy of 1000 miles on the new lower end now and have not used a drop of oil..I think the new pistons and rings along with the oil deflector has done the trick. :thumbs:

I have a 2003 Suburban Z71 5.3L. Used oil at what I thought was a rapid pace-- 1QT every 1,500 miles since 12K miles. I always did oil changes per recommendations with good, quality oil. (I have a '86 F150 302 farm truck that uses none, still to this day.) Brought it back to 2 dealers and they say "normal". Ok, whatever. Then, at 77k miles, both heads cracked and before I knew what was going on I think the antifreeze scored up the cylinder walls. Dealer got involved, said Aztec heads are prone to cracking (TSB issued) and it will cost $3000. Ended up fighting with GM and they covered under semi-warranty and I paid $1800. Dealer replaced heads, but smokes once in a while now. Still using high amounts of oil, 2QT every 1,500 miles, but now have 160,000 miles on it. No real power left for pulling horse trailer, so a replacement engine may be on it's way. Bottom line, my engine always used oil.

NEW 2011 Avalanche...purchased September 3, 2011.

 

Changed the oil today to Mobil 1 5W30 synthetic and got 5 quarts out of it...after only 2550 miles. Will wait until the next oil change to see if this is an anomaly or a pattern. If a pattern, and will be an oil burner forever, I do wish they would have at least put the Duramax logon on the side and made my 5.3 sound like a diesel!!!

 

So let me get this straight...6-speed tranny I have has been a real disappointment and now I discover the truck burns or at least utilizes a quart of oil every 3000 miles. As a lifelong Chevy owner I'm starting to ask what the heck I bought a Chevy for...

never researched the issue much, but it's been happening to me for awhile now.... decided to google the issue and this topic came up. haven't been an avid forum member just little time in life..

 

anyway... i have a 2008 AFM 5.3" 4WD Silverado...

 

i did an oil change at 3,000 miles when new and changed to mobile 1 and have used it ever since at 7500 intervals

 

every once in awhile, maybe once a week starting around 20k miles, it would puff a cloud of smoke at start-up, hmm. never paid attention much to it, alot going on in life

 

at 30,000 miles one morning, i start the car to go to work and holy $hit!! tapping knocking noises very loud scared me thought my truck was junk. 5-7 seconds later it went away. drove the truck to work, checked the oil, wasn't even showing on the stick! so i drained out the oil and did an oil change, i was about due anyway. topped it off, new filter.... rode around for a day checked level all OK no noises... still occassional puff of smoke at start-ups... a cloud rather.

 

now every 3-4 thousand miles i get the tap and check the oil and its empty... happened at 33,xxx.... happened at 36,500... and happened again 2 days ago i'm at 40,500 miles currently got a real good puff of smoke the other morning my neighbor even looked at me funny as the cloud of blue stinky smoke drifted across the street.. i added 2.5 quarts of oil to bring the level to the proper point on the stick... the oil consumption issue really took off strong on my truck somewhere in the late 20k range until now at 40k. never a sign of it for the first 2 years 25k miles.

 

my mods are as listed in my sig. air intake and exhaust. i do all service myself it's never been back to a dealer since i bought it (i'm a marine mechanic and powersports enthusiast) the contractor that neglects his house, i'm the mechanic that neglects this issue with my truck :thumbs:

interesting you say that. mine first did it around 28-30k.... if i park inclined nose down that's only time i get lifters slapping away in the morning if i'm low on oil.

 

if i park inclined nose up, then i'm more apt to get a smokey start-up. a trend i've noticed if of any relevance...

 

my smokey start-ups, CLOUDY smokey start-up like it's the 1970s.... it's not just a little bit of smoke.... would that mean more likely valve seals for oil to get in the top end when sitting cold...

Time to take it to the dealer and start an oil consumption test..The dealer just installed new pistons and rings in my truck. Don't wait for your warranty to expire...

Just got back from a long trip. From Delaware to Charlotte, NC. 533 miles one way towing 6,000 lbs. When I checked the oil level yesterday morning, level was at the 2nd dot.

 

When I checked the oil this morning before leaving, I needed to add a qt of oil.

 

I will check the level tomorrow morning. But I'm stopping in at the dealer again. Still using oil after their "valve cover" fix.

Sounds like its time for new pistons and rings as the damage has already been done.

Well, after my trip to Charlotte, I had to do another road trip up to New Jersey 2 days later. Around a 200 mile round trip. So between going to Charlotte and New Jersey, I put around 1500 miles on the truck.

 

Total oil usage was almost 2 1/2 qts.

 

Just stopped at the dealer a few minutes ago to report my findings. The service advisor took all my information and spoke to the Svc. Manager. 2nd week of Dec, they are going to put new rings in the bottom end.

 

At least they are going to try something different than the, "Lets try this first method" manufacturers usually do.

      Fluid Change Questions

      By Chuck FB · Posted

      There would be one way of determining the quality of the factory oil although probably more than a typical oil lab test, and that would be to draw out some oil from a new truck and send a sample to a lab that could do a more elaborate test of the oil. The issue with too little oil in the diff may not be the lack of lubrication of the diff bearings and gears themselves ( although a lack of oil volume for cooling ) but the wheel bearings because at some point the oil would be too low to properly get onto the spinning axle or fed along the axle tube. That was the claim by the local dealer from a couple of trucks in recent years that had the wheel bearings fail and they figured from lack of sufficient oil due to a severe underfilled diff and some of the bearing material made its way to the diff and it got damaged as well so the axle housings were just replaced on warranty. But your right that if the diff is over filled by whatever margin that it causes more churning of the oil than is desirable and that is no good either and can cause a pinion seal to leak. Also old oil I believe can tend to loose some of its properties like antifoaming and another good reason to change the diff oil every so often.

      I would be surprised if the diff's were not filled (with the cheapest gear lube) at the axle factory before being shipped to GM.  If you ever watched them building trucks they install the axles and all suspension parts with the frame upside down and then turn it over before its time to install the engine.     Too much gear lube in a axle can be worse than not enough especially with a lower quality GL where is get whipped up with entrained air (foam)  weakening its ability to lubricate.

      This is the 6.6 gasser section of the forum, you should either delete or modify your previous post as it is misleading for anyone looking for factual information on their 6.6 gas engine.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Well....I've done my first intake gasket. Probably wrong, but...we'll see?   Ultra black on the china walls and 1/4" up onto the sides of the intake gaskets. Permatex High Tack (couldn't find Gaskachinch) on the head side of the intake gasket. I read wrong and it says you're supposed to put it on the mating surface of the head, not the gasket. Hoping it's like a PB&J sandwich where it doesn't matter what side the PB goes on so long as there's jelly. That crap is messy/sticky and I got a dab or two on the intake port openings, tried to wipe it off. Hopefully it won't be a big deal and will only aid in sealing.   Per instructions I left the intake (top side) of the gasket dry except for a light smear of RTV around the coolant ports. Wiggling the intake in there was a bear but I had help to free me of surrounding wiring/stuff but I was basically able to set it straight down lined up with the bolt holes.   I did not think to wait until the RTV skinned over but there probably was 5-10 minutes while it sat before installing the intake.   Bolts finger tight first. Then, followed the Chilton's manual pattern to snug them to 15 lb-ft.   Waited a little over an hour, and then did the final torque in sequence again to 35 lb-ft.   Yesterday I replaced the fuel pressure regulator and got my new "nut and bolt kit" (fuel lines) installed. Damn GM used security torx on the spider, which I don't have, so I got scammed at the local HW store for an off-brand security Torx bit set.   The new driver's door mirror arrived yesterday, so, there's a chance this thing could be running and road legal tomorrow? I don't want to get my hopes up.   This will be my first time stabbing a distributor, too. Although, lucky me, someone else marked the old distributor for removal previously, I did see that. (Someone's been here before!!). Engine is still at TDC so it *should* be just a matter of transferring the mark to the new dizzy and rotating it into place.

      2027 GMC Sierra: Official Discussion

      By KARNUT · Posted

      He has his dad’s newer truck he’s put away. He has several old cars he rotates between him and his family. I’ve seen a restored square body and a SS Chevy truck he’s sometimes drives. He did raffle off a new suburban recently. As much as he is watched if he drove new stuff as a rule we’d know it. It would be fine by me. I don’t care what people prefer. I got one more new one in me. I’d rather my wife get one. I can’t get her out of the Genesis. Don’t tell anyone. I want her to get an electric truck. I want to put a generator in the back. Just because. She hasn’t bit yet.
