My 2005 Chevy 1500 Silverado 4.8 liter 5 speed uses no oil between changes.  It has just over 105,000 miles on it and I use Mobil 1 and change the oil and filter every 6,000 miles.

Not a GM but my wife's 2000 Jeep Cherokee Sport, 4.0 six cylinder and automatic transmission has 130,000 miles on it and uses no oil between oil changes, also use Mobil 1 with the oil change every 6,000 miles.

I can't imagine it has a manual transmission.


Do you engine brake with the electronic/padddle shifters?

I have only seen major blow by like that on some engines due to engine braking(ie. downshifting into a corner to 6k rpm)

Not normal.  

Call the service manager, tell him he's full of shit and that you want a leak down and compression test done immediately.  Ask him to throw it in the air and let you look under it for leaks.  If it has no leaks, I'd be wanting a short block from GM rickety fucking split while my car still has time left on the warranty.

Also have someone ride behind you while you go WOT and see if they see blue smoke from the exhaust.

I agree on all points but it is pretty well an industry standard that maximum allowable is 1qt per 1K. If it was my car I'd be bullshit to but good luck fighting that one.

Umm, you're supposed to put oil back in when the level drops unless you're an idiot. 1 quart per 1000 miles is what a lot of manufacturers call normal. Well, not normal but within spec.

my '97 911 burns less than that, and they do actually burn some oil.


I would be concerned on a late model vehicle using that much oil.

Guy at works wife has an Equinox. First motor they replaced heads, gave him the run around ect. Then they replaced the motor after it was constantly having issues relating to the oil. The motor it is on now is burning oil too. Although I think it is right on the threshold after having some more work done to it. POS. His wife has put more miles on the dealer vehicle than her own in the last two years of owning it.

1 quart per 1k miles would be unacceptable to me, but if they have that much tolerance in their specifications, maybe you can complain up the chain.

I bought a '93 Taurus SHO used from a dealership and during the first month noticed oil consumption.  I got it documented and kept complaining about it, had to go to a regional manager to get something done.  They put some anti-tamper sticker on the dipstick and had me come in again, and again, and again to test it.

Eventually they did replace the top end and the problems went away.  The service manager said they had a fly in a guy to work on the Yamaha motor- not sure if that was true or not.

Normal for a gm maybe. No where close normal for a properly functioning engine. 1 quart per 5k miles would be the very upper end of "normal".

So far in this thread, it's been stated that BMW and Honda also claim it's normal to burn a quart every 1000 miles. It ain't just a GM thing.

FWIW, my Saturn Ion burns a quart between oil changes (I do mine at 4500 mile intervals.) My '08 Duramax doesn't burn any oil, and neither does my wife's '12 Equinox.

Getting common as manufacturers are all going to rings with less tension and thus, less friction. Combine that with lighter oils [0w20 for example] and you will be seeing oil consumptions rise.

Oooohhhhh..............I bet a check through the EPA regs would reveal something about excessive particulates not being allowed.

My MB runs Mobil 1 0w40......service at 10k intervals, 155k miles, doesn't use a drop.  Engines that run like they are supposed to do not use enough oil between changes to notice.

The majority of GM's oil burning issues (for about 15 years now) are a result of piston slap. They don't like to admit that (because it would put them back into bankruptcy if they had to fix all of them), but it's the truth. You can't have audible metal smacking against metal and not have accelerated wear on the piston skirt and cylinder wall. The short skirt designs make engines more susceptible to the problem, but it's sloppy production that is the real issue.

I had a mid 90s Silverado with the 5.7L and it had a case of piston slap.  On cold startup, it would knock for about 10-20 seconds until the pistons started to get hot and expanded.  The truck had over 150k hard use miles on it, and even with the loose pistons it only used about 1/2 qt. of oil every oil change.

One more post - my 1986 IROC, 305 TPI, has 186,000 miles on it and leaks a quart between the 3,000 mile oil/filter changes.  I know it leaks it.  I see it on the garage floor.  It also puffs a little smoke sometimes on start up (Bowtie Salute they use to call it).  But hell, I ran the shit out of that car and it has 186,000 miles on it.

If I had a new car that "lost" oil I'd be pissed.  The only thing I drive that leaks/uses oil between changes is that IROC.  The Jeep, Fusion, Genesis Coupe and Silverado don't leak or use any between oil/filter changes.

Something's not right, no matter what the dealer says.

He's full of shit. Have a compression test and a leak-down test done by an independent mechanic. Catch an oil sample and have it analyzed for base metals and blow-by residues. If they aren't within limits, (which I doubt they will be at only 18,000 miles), have your attorney contact them to discuss the test results.


IMHO, they owe you a rebuild on your engine and an extension on your powertrain warranty.

Absolfuckinglutly!


A shit designed PCV system and excessive blow by is the reason these engines consume oil.
On the 08+ LS based engines GM in its wisdom designed the PCV port direclty over a rocker tip. This literally PUMPED oil directly into the PCV system.
Their fix was to redesign the baffle plate and move the hole over a inch.
Early LS based GM engines the gas velocity and volume was so high in the PCV system it would literally suck oil out of the valve cover.
Fucking morons!

At 145$ for a TB clean, tell them to shove brocken glass up their ass!
A 7$ bottle of cleaner will solve the issue in 10 minutes!



This a WELL know problem with performance guys. People spend enourmous energy redeisnging the PCV sytem on GM engines to stop oil consumption.

The 5.7L had longer piston skirts. Even if you got a loose one, it's not going to rock in the bore like any of  GM's newer designs will, and it's not going to have the same accelerated wear problems. And they don't usually burn a ton of oil when it's only audible for a few seconds at startup. It's when it progresses to the point of always being audible that it's usually going to start burning major amounts of oil.

It isnt a GM specific issue.  Toyota's acceptable oil burn is 1qt per 1200miles.

This is because the newer engines are using a lower tensile oil ring on the piston.  These rings help with MPG but dont seal as well.  Also, newer cars are using lighter weight oils as well and leaving a film on the piston walls which is burnt up in the power stroke.  Its unfortunately a fact of life now.  Some will burn a bit more than others depending on driving style.

As long as you aren't seeing plug fowling there really isnt anything you can do about it.  Also with these new PVC systems, you are seeing a lot of atomized oil getting pushed back into the intake manifold and hopefully burned off.  Its really bad on Hemi's. There are reports of qrts of oil laying on the bottom of the intake manifold on some SRT motors but since the Hemi and Toyota 5.7 hold 7-7.5 qts, a lot of people dont notice.  This is another reason why a lot of people are using catch cans.

I think Porshe is 1 qt per 2k miles, but they are using 0w40 syn which is really thin.  

Honda, Nissan and GM is 1qt per 2K

So basically the newer engines are burning more oil because they dont seal as well trying to reduce friction and are using much lighter oil weights than engines in the 90's and below.  Also a lot of oil is floating around in the PVC system if your vehicle is equipped with one.

For GM yeah.

My Automotive engineering professor at York tech, a huge Chevy fan, would tell you a Chevy isn't running right  unless it's losing a little oil.

Mostly, it was a joke, but there was some truth in it.

I have a 95 Mustang right now, 5.0l convertible with 170K miles on it. I'm getting ready to change the oil in it. I'm behind, even on the 5000 miles schedule I use with Mobile 1 15w/50. I'm on about 6500 right now.

I checked the oil the other day as I was going to change it, then it came up a bad storm. I'm not even a half a cup, not a quart, a half a cup low.

Anytime something uses that much oil new I'd be talking about it with somebody. There's going to be losses over time in oil as it gets burned, turned to carbon etc, more with conventional oils, but a quart per 1000 miles is crazy. I could see a quart per 5000 miles as being sort of normal for some engines but not per 1000, that sounds like you have a problem, or it's piss poor engineering.

Yes that carbon is blowby gas/exhaust/oil vapor from your crankcase breather getting sucked into your intake. All engines make a little blowby during the power stroke. Excessive blowby is caused by bad compression rings or loose pistons.

Alternatively when you let off the gas (close the throttle plate) it creates vacuum in the cylinder that sucks oil up past your (bad) oil rings into the combustion chamber and burns it.

GM used to take the time to make sure high spec size pistons got matched with a high spec cylinders, low spec size pistons got matched with low spec size cylinders. Now they just throw them in willy nilly and hope for the best. When you lose the GM lottery and get a small piston in a large bore you get piston slap and oil consumption.

Normal for a gm maybe. No where close normal for a properly functioning engine. 1 quart per 5k miles would be the very upper end of "normal".

BMW Motorsport engines have a spec of 1 quart for every 750 miles. Is it a lot? Yes. But I still would say they are properly functioning engines and I haven't seen any major damage due to oil consumption. However with BMW's you get free oil changes and top off's while you're under warranty.

He's full of shit. Have a compression test and a leak-down test done by an independent mechanic. Catch an oil sample and have it analyzed for base metals and blow-by residues. If they aren't within limits, (which I doubt they will be at only 18,000 miles), have your attorney contact them to discuss the test results.


IMHO, they owe you a rebuild on your engine and an extension on your powertrain warranty.

I have a 2011 Equinox with another year or 18,000 miles on full power train warranty that burns oil like a madman. It burns about a quart every 1000 miles to which the Service Manager called and said that GM says is normal. Supposedly this vehicle is supposed to be filled with DEXOS oil so it costs me about $11/quart which at this pace is once a month.

This seems absurd to me. Anyone verify what he said? What's my next step from here?

At 18,000 miles it could be it hasn't seated the rings yet but I doubt it with modern machining and rings they are normally seated by the time its got a few miles on it... I would think its more likely valve guides/seal issues  to burn a qt every 1000 miles..rings should be showing blue smoke on acceleration out the exhaust with that kind of usage....

Not normal, but its probably within the limits set by the manufacturer.
