I took my car to the dealer because of it burning roughly a quart every thousand miles. The dealer called me the next day saying that "GM is developing a part to stop the oil from splashing around while the car is in DOD mode". When i get my car back today im going to ask for some kind of documentation of this and ill post it here.

 

do itttttt

im only losing a quart every 2k miles and I do 75% highway driving

 

Here striaght from GM

The accepted rate of oil consumption for engines used in the vehicles referenced is 0.946 liter (1 qt) in 3200 km (2000 mi).

Important: This rate only applies to personal use vehicles, under warranty, that are driven in a non-aggressive manner and maintained in accordance with the appropriate maintenance schedule, with less than 58,000 km (36,000 mi), or driven at legal speeds in an unloaded (for trucks) condition.


Important: This rate does not apply to vehicles that are driven in an aggressive manner, at high RPM, high speeds, or in a loaded condition (for trucks). Oil consumption for vehicles driven under these conditions will be more.

Many factors can affect a customer's concern with oil consumption. Driving habits and vehicle maintenance vary from owner to owner. Thoroughly evaluate each case before deciding whether the vehicle in question has abnormal engine oil consumption.



If this concern is encountered, follow the steps below:

•Visually inspect the entire engine and the underside of the vehicle for any evidence of oil leaks and repair them as necessary.
•If the vehicle has an engine misfire due to a spark plug that is obviously oil fouled, skip to step 3 since this proves that it has an obvious oil consumption concern. If not, perform an oil consumption test as outlined in the latest version of oil consumption of 01-06-01-011 to verify the concern before proceeding to step 3. Allow the vehicle to sit on a level surface with the engine off This PI was superseded to repair described in this PI. Please discard PIP4814A. for at least 10 minutes to allow the entire engine to drain back to the oil pan before checking the engine oil level and adding oil.
Compare the oil consumption test results to one of the scenarios below to determine further direction:

If oil consumption is Less than 1 quart of oil every 2,000 miles and no low oil light has been experienced, no repairs should be performed as this should be considered acceptable oil consumption as outlined in the latest version of 01-06-01-011.

If oil consumption is Less than 1 quart of oil every 2,000 miles but the customer has experienced a low oil light, check for proper oil level sensor operation.

If oil consumption is More than 1 quart every 2,000 miles, proceed to step 3.

•Perform the PCV inspections outlined in the latest version of PIP4492.
•Check for any obvious valve seal concerns and repair as necessary.
•If the steps above are followed without isolating the cause of this concern, this is most likely the result of AFM pressure relief valve oil accumulating on the bottom of the cylinders when active fuel management is enabled. Over time, this may eventually lead to the stuck oil control rings, poor ring sealing, and increased oil consumption.
See if that is the same thing they give you.

 

Seems to me programming out DOD will lessen the oil consumption and maybe get rid of it all together. I have mine programmed out and I do not burn oil or loose any oil. I go 4500 - 5000 miles between oil changes too and still the oil level remains at what it started with. Could be the easiest solution...

I wondered why mine never 'used' oil. DoD delete was great on many fronts apparently.

 

im on the last step concerning the rings, will take it in this month sometime for the overhaul

 

Before the delete i went through about a quart or so every 4000-5000 miles..After the delete I am at about 4500 and have not burned any.

 

yeah... DOD disable FTW!!!

 

Screw DOD

 

Ya you could possibly print that out if you want that is straight from GM for a 2006 GP 5.3 FWD.

I would take it in and have the rings replaced then soon after delete DOD

 

Yeah we have that on some other post around here and i took that in to the dealer and he said that GM is developing a "shield to stop it from splashing around" so the replacing the rings wouldnt be needed

 

That aint true cause there are no current TSB or bullitens on this so called shield. They just dont wanna do the work I work at the a dealer so I know.

 

Im now sure I have this problem, about 1k after adding a quart im down a quart again and my #4 spark plug was oil fouled and had a misfire, out of warranty what should I do?

 

take it straight to the dealer , you have the problem. take any mods off though as it can void your warranty or their will to fix it

 

im taking my car into the dealer tomorrow for the last test on oil consumption. Ill let you guys know what they say about that "splash guard".

 

06 gxp though.......out of warranty, still take it in?

 

They will most likely charge you. Mines an 06 but, I bought mine with a gm certified like new warranty.

 

if you dont have warranty the best thing for you to do is disable DOD

 

ya looks like im gonna start saving for a tuner

 

Still a waiting game:
