06 Chevy 4.8 burning oil


Hi Dougles

The short answer on this is that almost any 9 year old vehicle burns oil. That said, it's generally the miles more than the years that lead to that. Wear on the cylinder walls and piston rings can lead to oil burning. Leaks can lose you oil, but you'll likely then notice oil puddles where you park. A more worrisome possibility would be if you're also losing coolant, as that could mean your head gasket is circling the grave. White smoke, bubbly or burst radiator hoses, or constantly needing to top off coolant could be a warning sign there.

On a vehicle of this pedigree, part of the question on burning oil is whether the car still runs ok, and how much it's costing you in extra oil. if you're burning an extra quart a month, you can dump a lot of years' worth of oil in before it'll come anywhere close to getting the valves, head, and pistons all redone. A lot of years.

Hoping this helps!

Believe it or not, it is normal for these engines to use about a quart every 2000 even when they are essentially new. Note that I said, "use", not "burn". The combination of higher compression and operating temperatures causes oil to pass through the engine. You might notice your tail pipes have a good coating on the inside. I managed to slow the process by converting to Mobil 1 0W40. I get much better performance and I only use a quart every 3500-4000.

Burning oil 2001


Usually the problem is piston rings. But it could also be something going on with the PCV system.
It could even be something as simple as changing the brand or weight of oil you are using.
Two quarts of oil in 3000 miles is not a huge amount, so it may be tough to find the cause. One quart with every tank of gas would be alot.

Hello, 1 quart in three thousand miles, great, awesome, wonderful don't worry about it. As long as you know it. This is normal for a lot of engines. For many Chrysler Motor Co. there engine would use a quart of oil in the first 500 miles and after that, none. Oil change, another quart in 500 miles.

Bought certified BMX 335i convertible and after only 3000 miles of driving the low oil light is on. Is this normal oil consumption or is there a problem?


Though I am not familiar with the 2007 model, on the e46s, I know that the low oil light comes on when you are down only about 1/2 quart. Does your model have a dip stick?
A half quart in 3000 miles is not cause for concern. Most of them burn a bit less than that, at least during the first 200k miles, but some burn more. It depends to some extent what kind of oil you are using. It will burn more Mobile1 than it will Castrol Syntec, for example.
I have an '04 330 that uses about a half quart in 7k miles between oil changes, and an '04 325 that goes through a quart every thousand miles. I am only a little concerned about the 325. I would not be at all concerned about a half quart in 3k miles.

have you checked the pcv valve ( positive crankcase ventilation ). plugged pvc symtoms-- can contribute to sludging of engine. it will build up pressure in crankcase if plugged. the pressure can blow out seals, it can also force oil past oil rings and burn oil up in engine. shake pcv valve, if it rattles its ok. if all else fails check oil pan gasket and filter also. ive seen holes in oil filters or they are loose. and upon driving, pressure is put on oil and it blows out.

Engine oil low light message comes on every 3000 miles and is always quart or more low 2007 chevy suburban 1500


Hard acceleration will burn more oil, also the 5.3l V8s are well known burning oil. so just check the oil every time you fiil up with fuel. Seriously, your already waiting for the tank to fill so grab a towel and check the oil level- if its low put a bit in. Trust me, you dont want to have to replace that engine just because you didnt want to pop the hood!

It is normal to use over a quart of oil before oil change


My 1993 voyager is like that. It may burn some , it definitely leaks some , and it could be just sending some through the PCV valve. Oil leaks and burning oil causes pollution . If you can fix it with a new seal or a valve cover gasket it is easier than constantly checking your oil. Temperature, trailering, speed, outdoor temperature, and engine RPM all can be factors if you are losing oil. If your engine is a quart down, the engine oil consumption rate doubles or triples. In other words the lower the oil level the faster it disappears. High mile cars will drive for years as long as you add oil when it is needed (keep the oil level between the marks). Fix any obvious leaks. Then determine your oil change interval (3000 miles, 4000 miles, 5000 miles). I change between 4000 and 5000 miles. If i am a quart low at 3500 I add a quart. If I am a quart low at 4500 miles I just change the oil in the car. A good practice is to carry a quart of oil in your vehicle just in case you need it. It is far cheaper to add a quart when needed than to go to the dealer once to maybe fix a problem that they may not be able to find or fix. Older engines (even some newer ones) just use oil , especially in hotter climates. Fix the obvious and carry a quart.

Have an oil change every 3000 miles by about 2000 miles it is allready a quart to 2 low and there is no visable oil leak


What you describe is normal for the Northstar engine, they do tend to burn oil.
It sounds a lot but by contrast, consider that BMW recommends checking the oil level every time you fill up at the gas station on some of their models (M3,M5 etc).

2004 pontiac grand prix 71000 milesis burning oil. no leaks no smoke


How many miles do you go before you have to add oil. GM actually states that one quart of oil every 2000 miles is considered normal. I personally think that one quart every 3000 miles is normal esp at higher miles. As an engine wears things such as valve seals and rings get worn and allow oil to seep past and will burn, this can be in such small amounts that you will not notice the smoke and is normal engine wear. The life cycle of an engine is considered 100k miles by the designers, even though we all know they will go far beyond that. If your car has the 3.1 or the 3.4 liter engine you may want to check in the engine coolant for signs of oil, it is a common problem for the oil to seep into the cooling system but is not usually enough to make a noticable drop in oil level. If you are only using about one qt every 3k miles or so i would not worry about it if you have had it checked for leaks already.
