My 2008 chevy avalanche is burning 1 quart of oil every 1000 miles


How many miles on your vehicle ? Do you see any leak spots on the ground from the truck ? Blue exhaust , oil burning , valve guide seals , piston rings , PCV clogged .

Oil Consumption Diagnosis
Checks
Causes
Excessive oil consumption, not due to leaks, is the use of 1 L (1 qt) or more of engine oil within 3 200 kilometers (2,000 miles).
Preliminary
The causes of excessive oil consumption may include the following conditions:
• External oil leaks
Refer to Oil Leak Diagnosis .
• Incorrect oil level or improper reading of the oil level indicator
With the vehicle on a level surface, run the engine for a few minutes, allow adequate drain down time, 2-3 minutes, and measure for the correct engine oil level.
• Improper oil viscosity
Refer to the vehicle owners manual and use the recommended SAE grade and viscosity for the prevailing temperatures.
• Continuous high speed driving and/or severe usage
• Crankcase ventilation system restrictions or malfunctioning components
Refer to Crankcase Ventilation System Inspection/Diagnosis .
• Worn valve guides and/or valve stems
• Worn or improperly installed valve stem oil seals
Refer to Spark Plug Inspection .
• Piston rings broken, worn, or not seated properly
Allow adequate time for the rings to seat.
Replace worn piston rings, as necessary.
Refer to Cylinder Leakage Test .
• Piston and rings improperly installed or not fitted to the cylinder bore
Refer to Lower Engine Noise, Regardless of Engine Speed

I have a volkswagon 2008 Eos and have been told by the dealer it is normal for it to use oil. Now I hear a knock coming from the exaust. It has 65000 miles on it just out of warranty.


oil consumption of say 1/2 litre in 5.000miles would be normal even 1 litre in 5.000miles would be ok but any thing else is staring to be excessive. Oil consumption is an indication of a problem with the oil control rings and valve stem seals . Add to that your statement of a knock coming from the exhaust I would be inclined to have a compression test done to determine the condition of the engine . I consider 65.000 miles to be a little young for bad oil consumption so with the noise I would suspect a broken ring and a scored bore

I recently bought a 2003 Santa Fe. It's burning a quart of oil every 1,000 miles.


Hi,
If you do some more research you'll see that 1 Qt per 1K miles is considered acceptable, as the dealer stated....not that I agree either!

You may try replacing the PCV valve and ensuring the valves are adjusted properly.

Also, try a different oil - maybe a different weight may help.

I WOULD replace the O2 sensor as it can affect the amount of fuel that is used and may actually dilute the oil if it's getting past the rings.

Just to ensure the engine is healthy you can get a Compression and Leakdown test down. This will tell you the 'health' of the engine.

Go look on the Hyundai/Kia forums for oil consumption, too. You might come across something specific to your model.

I purchased an 07 Grand Caravan on June 24, 2010 with 48,000 miles on it. My mother borrowed the car on July 9th. When I checked all of the fluids, there was no oil in the engine, and no lights were on. I...


You should never buy any van type vehicle, in the first place,
the transaxle will fail any day.
I used to own a trans repair shop

Other then sell it,I would,I won't ride in one, not safe

Your correct,you should go 5000 miles and maybe use a 1/2 qt,
on most vehicles, none.

So you do a cylinder leak down test
Check Emission Gas Readings,to see what that shows
I suspect a broken oil ring,scored cylinder, broken piston
skirt or serious cylinder head issues.

Never go to a dealer. Calling or Visiting is okey

There is a lot wrong with "low oil" and low oil is not normal in a low mileage healthy engine.

The dealer is fobbing you off in the hope you will go away.

If the oil is being changed at least every 5000 miles or so there should be minimum oil depletion between changes with only very minor top up needed. Some oil consumption is normal but it should be minimal.

If the oil level is dropping to a very low level in about 4000 - 5000 miles of normal motoring you have a significant problem. The oil is either leaking out or the engine is burning excessive oil or a combination. If there is no leak through faulty seals or by other means such as oil escaping into the cooling passages of the engine, then there is excessive burning.

These engines are known for excessive oil consumption because the problem is a common one in the 06, 05, 04 and previous year builds back to about 98/99. The dealers know all about this problem - as does BMW - and they will try to fob you off until the car is out of warranty because the fix is expensive.

From what you say the problem has not been fixed on your car. Document the oil loss and insist on your warranty rights because your engine is using excessive oil and this is NOT normal in a properly functioning motor with as few miles as yours has. Make it clear to the dealer that you are well aware that excessive oil consumption is a common problem in many of the 325 petrol engines and you want it fixed under warranty.

Then sell the car as these vehicles will cost you quite a bit in repairs once out of warranty and once you clock up around 60000 miles or more. If you have an auto you can expect major problems at about 65000 miles (later if you are lucky) and replacement of the transmission will be necessary. Once you notice any significant problem with the auto transmission it is on it's way out.

Vw passat 2008, 3600 miles, using oil, has soot at exhaust pipes


the oil consumption could be worn piston rings or the egr is clogged and forcing oil into the air intake but that new of a car its unlikely unless someone sugared the gas tank the sooty exhaust could be from the oil consumption
