2001 Toyota Corolla, Burning Oil rapidly

I have a 2001 Toyota Corolla with approximately 130K miles. For some reason the car has started to burn oil rapidly (about 3 quarts a month). The mechanic says that the problem is due to high mileage and I should have the entire engine replaced, which I find hard to believe as I have friends that have Toyotas with 259K plus miles on them and they did not require a new engine. Is this a common problem? Any suggestions? I have regular maintenance performed on the car and any repairs as they come up. My car is also burning oil badly. It's only been 2k since my last oil change and the dipstick is dry. I even had the high mileage oil put in.
This is a big deal breaker for any future GM or Toyota cars.

    Just read your post. my car has similar problem. My car is burning oil. it has about 130K on odometer but it burns like crazy. I add 1 quart 5w30 oil every 2 days thats about 80 miles drive. I went to mechanic and he suggested me to change engine for 2k (about 60% of the price i paid for). I wonder if the car would be fine after engine replacement. I am also confused: If i change engine now.. then transmission might have problem later.. and if that gets fixed.. then it might be smth else.. so if i go on adding 1 quart for every 80-100 miles for long run.. how long does the car last. let me know wat did u finally do?

Hi, the main cause of major oil consumption is due to cylinder wall deterioration. this is caused be bad piston ring sets that tend to chip of tiny pieces of the cylinder walls over a long period of time. this will start to show in engines with high millage. this will also lead to compression loss as well if it is not fixed soon.

To fix this issue within the cylinder walls, they will have to be machined and a new set of piston rings will have to be fitted around each affected piston. this will stop the oil from leaking into the combustion chamber and it will restore the compression rate as well.

3 qts per month is a huge amount of oil. I think you and the mechanic are both correct though. As you say - just having alot of miles on a motor doesn't mean it will be an oil eater. But the mechanic is correct in that this problem usually exhibits on older engines. At that rate you should be seeing smoke coming out the exhaust from the oil burning off. Unfortunately, the easiest and quickest way to take care of this is to replace the engine.

Toyota burning oil


If you are sure it has no leaks, the only other possibilities are worn oil rings or valve stem seals. Generally if the oil rings are worn then the compression rings are as well, so get a compression test. If readings are down on spec, which is about 150 psi., add a tablespoon of engine oil to each cylinder in turn through the plug hole. If readings rise, then it is worn rings at fault. If not, then suspect the valve stem seals.

On these engines though, there are several characteristic oil leaks which may be hard to spot, being the cam cover gasket, crank nose seal, and the distributor o-ring seal.

I own a 2001 Toyota corolla, I am burning about a quart of oil every 300 miles....


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.

Engine burning oil


you should be checking the Oil Level more often than 5K miles but my 2009 Toyota Corolla burns oil (Not a LEAK), just consumes oil (1 Quart every 2K miles). It has done this since it was Brand New and Toyota said (ADD MORE OIL).... So that is what we have done. Watch the level and make sure you add more.

Took 2007 Toyota camry with 113,000miles on it to dealer because it is burning aolot of oil rapidly - they came back and told me that pistons are shot and that it needs a partial rebuild. They told me not...


generaly oil burning will not cause the engine to seize, just the lack of oil ,if it burning it real fast you could run out of oil and then seize the engine,how much oil does it burn, the industry standard is 1 qt. per 1000 miles, if it using more than that it could be the rings on the piston, first has the engine oil been changed regular, if it has been then i would suspect that its not the rings and more like the valve guides and seals

What is the recomended oil I should use on a toyota corolla 1986


Due to tight tolerances on Japanese engines the factory most likely recommends 5W30 I on the other hand recommend :
If the engine has less than 50,000 miles 10W30.
If it has over 50,000 miles on it and isn't burning oil (black smoke)
i use 10W40.
If it's over 150,000 and is a little sloppy ( burns a little oil)
I use 10W40 in the winter and 20W50 in the summer.

My 2001 Toyota Highlander is burning oil but does not show the symptoms of oil burning. After 500 to 1000 miles, the dipstick does not show any oil. What would cause this and what solutions are there?...


If you see no signs of burning oil ie blue smoke from exhaust, ticking from the engine, then most likely you have a valve cover gasket leak. The reason you wouldn't see the oil in the driveway is the oil is burning off on the exhaust manifold. Check around the valve cover gasket for seepage (usually around the bolts).

Toyota corolla 2002 CE , car milage 140,000 , Burning oil, every 1000 mile have to add a quart of oil. There are NO oil leaks. Could it be the valve seals need to be replaced? How much will it cost me to...


Well looking at the age of your car,it would need a valve seals replacement,in order to fix your problem.This would cost you around for about 1500-2000 $.

Didn't change the oil for 20K then oil light came


Black some is from too much fuel, blue smoke is from burning oil. Keep an eye on oil consumption now. If your check engine light doesn't come on, just keep an eye on it. 20k miles??? Dude!

Oil Lick


when the car is running do you have blue smoke from the exhaust? :If so then the piston rings are fried. If not then do you have oil on the motor around the valve covers? If so then the valve cover gaskets needs replacement.

2001 Toyota Corolla, Burning Oil rapidly


Take your vehicle back to your mechanic, and have him perform a DRY, then a WET compression test. Please provide both readings back to me. In the meantime, ask him what it would cost you to him replace the piston rings. This is your problem. The 2 tests will simply verify me thinking.
