Does your 5.7 use any? If so, how much?

Does your 5.7 use any? If so, how much?
All engines require oil to lubricate and protect the load bearing and internal moving parts from wear including cylinder walls, pistons and piston rings. When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the power stroke, part of this oil layer is consumed in the combustion process. As a result, varying rates of oil consumption are accepted as normal in all engines.


Excessive oil consumption, not due to leaks, is the use of 1 liter (1 quart) of engine oil within 3 200 kilometers (2,000 miles). However, during initial engine break-in periods 4 828-6 437 kilometers (3,000-4,000 miles), oil consumption may exceed 1 liter (1 quart) or more. The causes of excessive oil consumption include the following conditions:

External oil leaks Tighten the bolts and/or replace gaskets and oil seals as necessary.
Incorrect oil level or improper reading of oil level indicator With the vehicle on a level surface, allow adequate drain down time and check for the correct oil level.
Improper oil viscosity Use recommended SAE viscosity for the prevailing temperatures.
Continuous high speed driving and/or severe usage
Crankcase ventilation system restrictions or malfunctioning components
Valve guides and/or valve stem oil seals worn, damaged, or the seal omitted Ream the valve guides and install oversize service valves and/or new valve stem oil seals.
Piston rings broken, improperly installed, worn, or not seated properly Allow adequate time for the piston rings to seat. Replace broken or worn piston rings as necessary.
Piston improperly installed or miss-fitted

I've owned a 2007 6.0L silverado 1500 LTZ that consumes oil as it's normal operation to the tune of 1 qt per 1K. Per GM, this is normal but everyone that I speak to about it says "how can that be normal?". By posting on here I'm looking for some type of support/fix to my problem. I have spoken to two different dealerships, & GM's hot line and nobody listens.

The only information I was able to find in the manual is: If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life system whenever the oil is changed. You can find this on page 506 of your owner’s manual. I would take this to mean that an oil change should be done at every 3,000 miles. I can look into this further if you could send me the VIN in a private message. Hope to hear from you soon.

Best to start your own post/New thread and give all info with you problem.
Like what mileage and what kind of oil and filter and service history.
Any leakage or engine running problems?
What mileage did it start using oil?
Is the oil usage staying the same?
Have you tryed a different brand of oil?

A bad PCV system, can cause the intake to vacuum more oil into the combustion chambers.

Ok, here is GM's response to my question:

"
Have you had the vehicle in for the oil consumption test? I am not showing anything in my resources that this is abnormal. I would recommend continuing to work with your dealership. Please feel free to keep me informed on any further developments. Thank you.

Tricia, GM Customer Service. "

In response to Tricia's oil consumption test, is that GM does not do any test on the vechicle but rather notes down the mileage and oil level. This can only be started and continued if you pay for the oil changes! With the way the economy is right now, for $10 I change my own oil and document any changes in the vechicle performance. This of course can not be used by GM :frown:

As far as working with the dealership, they can not do anything since the techical bulletin states 3 qts of oil every 3,000 miles and can be as high as 6 qts per 3,000 miles is normal.

Therefore, at this time, per Tricia's wording above, GM clearly does not care about their customer base, I've seen an inferior product and will never purchase another GM truck or car for that fact. As with anyone that asks me about my experience with GM, I say NEVER NEVER purchase their products...

GM is not as bad as you describe , but much worse !

high oil consumption would be when you get tickets from the police for leaving a smoke screen behind you ...

with a vehicle like this it would be best to dump it . don't even think of trying to repair as it would be far to costly.


start a new post with the vehicle history..I want to know details on how this has occured to your vehicle...

also vehicle engine type details.

oil used/filter types/viscosity/intervals/who did it/ etc.....

Okay...the issue with the oil consumption on the 07 6.0 is a little much and the recommended consumption is 2 to 2.5 quarts of oil per 2,000 to 2,500 miles. If you are using more than that, you should take it in. Seeing as a lot of the 2007 models have the 5 year - 100,00 mile power train warranty. There is a valve in the oil pan that requires a baffle of sorts to be installed and your lifters could be of a concern on the passenger side. I would be firm with this and keep trying. They can put oil dye in the vehicle and let you drive it for how ever long and then bring it back for them to examine. Also I would chekck the rear main seal

my 95 K2500 with 5.7 v-8 uses about 1 qt in about 2500 miles and I think most of that is a leak.

my 95 K2500 with 5.7 v-8 uses about 1 qt in about 2500 miles and I think most of that is a leak.

your oil consumption is most likely crankcase blow by gases causing the oil to create vapor which ends up being consumed in the engine by way oy the PCV venting system. 1 qt on 2500miles with regular dino oil in a work truck this age is good and normal with correct intervals of service.

when GM ignores 1 qt of oil consumption with a vehicle less than 5 yrs old, per 1000 miles , this is just to not repair the defect.

this is an amount that creates pollution and damages the pollution controlling components .

The only reason I responded was because the original question was about the 5.7 and it looked like everyone was talking about the 6.0.
As for the synthetic oil I have only been using it for the last three oil changes and I have not noticed any real difference in oil consumtion.
I only change oil once a year because the truck usually does not go 3000 miles in a year. It is a snow plow and only has 74,000 miles.

since you are plowing the amount of oil you use is quite good..using synthetic on extending the time of oil servicing is a good way to go !

Put an oil catch can on, and use a external filter for PCV Vent!
Don't forget to block the air duct work going to the Inake, else unmetered air(vacuum leak) will give you problems.

With gas almost $4.00 a gallon, who can afford burning extra guarts of Mobile 1 oil?
