Don't know of any recalls but first thing you want to do is look at the spark plugs and see which are black and fouled. that is the cylinder having a problem. Also make sure it isn't leaking anywhere. (check off, and running)
If you are still in warranty (if bought used with extended) bring it to the dealer.
Could be a broken ring or really bad valve guide or seal.

Burning Oil


we check oil every other fuel fill up. on old cars, every fill up
did you run car 10,000 miles to a oil change? unstated.
1qt/3000 miles is perfectly OK.
so 10000 mles is 3.3 quarts burned and off the top of the dip stick
if you drive fast, it burns more, got a heavy foot, or load in back>?
if you had done it right, you'd have already learned YOUR engines
consumption rates, and learned to check when IT , needs checking
we do this on all engines. all machines.
all engines burn oil, the exception , a church car, new, and never driven, far, or fast or for 10000 miles to an oil change.

your mech, was right, he was thinking , you dont check oil?

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.
I would drive that Chevy around the world. I wish you many hundreds of thousands of miles. GB..stewbison

Using 1 quart a mth. no visible leakage. i can tell when it starts getting low by how it runs. live in mx. 110 /87% humidity. is this normal usage? i never had to put in extra oil and get it changed every...


One quart per month is a bit more than I'd expect but you didn't mention how many miles you drive during that month.If you live where the ambient temps are very warm, it may help to use a good synthetic. Synthetic oils do not burn off or break down chemically as fast as conventional oils do. I'd use a 20w40 grade.
Depending on the miles you've driven you shouldn't have excessive ring wear but the valve stem seals may have dried out and cracked. If the usage remains constant and there is no smoking etc, you could either leave it alone or have new seals installed.
Average driving is approximately 1,000 miles per month so when figuring consumption, use that as a baseline. One quart per 1,000 miles in very hot conditions is a bit high....I'd expect to see 1/2 qt or slightly less. One odd thing though is that generally, especially in an engine that holds six quarts to begin with, at five quarts, the engine should not feel any different!!!
Also.....you use miles to determine oil change intervals. Oil is best changed at between 3K and 4K miles. Only way you use the 3month method is if you don't use it much. (you can run most good synthetics longer than that)

2004 Rodeo, 103,000 miles. no oil leaks so I guess its burning oil. Oil is maybe a qt. low after 1000 since change. Engine still sounds fine but I don't know what a new engine sounds like since I bought...


if you are using a quart of oil every 1000miles,that is NORMAL FOR A MODERN ENGINE.thats why they last so much longer than the old technology.you could try 20/50 oil when you next change as that will help.but worry when it gets to pint every 350 miles.

Loosing engine oil,don't know ware it's going


Whenever I encounter an engine that's missing oil I always start with the basics. First I take a good look underneath and check for any drips, no matter how small, as a leaky sending unit, oil filter, or cooler line won't leak once the engine is off. If you can park on the same spot, preferably over a clean piece of cardboard, it makes it a lot easier to spot any drips. If no drips are present then I change engine oil and filter using a top grade oil and fill the level to exactly the full mark on the dipstick. I do this because most engines will burn oil if the oil is dirty and old enough. At that point I check the oil every 100 miles or so [after the engine has been off for a few minutes] and see how long it takes before the engine is a quart low or down to the "Add" mark. Once you have this information then you can decide what or if you need to do anything. As for what's normal oil consumption? Most vehicles won't use a quart in a 3,000 mile service interval but I've seen new vehicles that take a quart every 1000 miles or so, thus there's really no good solid answer although I think a quart per thousand is excessive...but often expensive to fix if it's actually burning it. Hope this helps and good luck!

How much oil usage is normal?


1 quart every 2000 miles. Not all cars are created equal. The same model may burn alot less or even more.

Blue smoke


Blue smoke is never a good thing....

Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles.
How did the engine oil get inside the cylinder in the first place? The car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

your engine has worn valve guides, piston rings An engine that burns a lot of oil (more than a quart in 500 miles) is an engine that needs to be overhauled. Normal oil consumption should be a quart or less in 1500 miles. Most newer engines consume less than half a quart of oil between oil changes (every 3000 miles). So if your engine is burning oil, it's essentially worn out and needs to be repaired.
Because the cost of overhauling or replacing an engine often exceeds the value of an older car or truck, many people will just keep on driving a "mosquito fogger" in spite of the blue clouds of smoke it leaves behind. Never mind the pollution it causes, oil is cheaper than a new or rebuilt engine they reason. That philosophy may be okay if you live out in the sticks somewhere. But in urban areas that require periodic vehicle emissions testing, an engine that's burning oil usually won't pass the test because of excessive hydrocarbon (HC) emissions. You may get by on a waiver after you've spent some money (in vain) on a tune-up, but the fact remains you're still a polluter.
An engine that burns a lot of oil will also eventually foul the spark plugs. Thick, black oily deposits build up on the plugs until they cease to fire. Then the engine misfires and loses power. Cleaning or changing the plugs may temporarily solve the problem, but sooner or later they'll foul out again.
Forget about "miracle" oil additives or pills that claim to stop oil burning. They don't. Better to save your money and put it towards a valve job and new set of rings.

Burning a lot of oil


Hi:
A quart every 1000 miles is not unusual, but can get expensive if you are using synthetic oil. Have you always used that in this Jeep? Even though synthetic oil is of higher lubricating quality than conventional oil, it is still thinner, or has less viscousity than normal oil too. What this often means is that an older engine with slightly worn valve seals or some engine wear might consume more oil when you use synthetic. This is not a problem, really, as long as you keep tabs on your oil level.

If you want to experiment around, once it gets warmer out, you could try some 20w-50 oil and see if your oil consumption drops, or even try adding some Lucas Oil stabilizer to your next oil change. If this helps you know that part of your consumption is due to the thinner oil you were using.
