#81 of 85 2007 Aveo Engine oil sludge - need advice & I have advice.
Feb 21, 2010 (7:44 pm)
Over the last week, I have learned more about oil sludge than I ever thought I would know.
My 2007 Chevy Aveo (5dr Automatic) oil light came on and a faint ticking was coming from the engine. I immediately drove it
1/2 mile to oil lube and they said I need to tow it to a shop. It did not seize up.. I had it towed to dealership. I have never had a problem with this car before that. It is still under the 5yr/100000 mile powertrain warranty.
I bought it used from a reputable rental company Enterprise in March 2008 29000 miles. Unfortunately they did not give me their maintenance records and I did not think to ask at the time.
I have all my maintenance records showing timely oil changes with Pennzoil 5W30 oil.
The car has 68000 miles on it. I use it for business.
Some stop and go(never idling or dusty roads) and some highway at 60 mpg for 6 miles or more.
The longest between changes was 5600. But most were between 3100 and 4500.
GM's recommended interval is 3000 for short trip(5 miles). Dealership is satisfied with my records, said I did fine with the maintenance.
GM warranty requires ALL the maintenance records even from Enterprise Car Sales, which Enterprise told me they "purged" the records which pretty much means I cant prove good maintenance. Dealership says that the vehicle could have been abused/neglected before I bought it. That means GM wont pay. At this point I have become distrusting of everyone involved.
Now the dealership service center says that GM is requiring them to tear down the motor to see if there is any coolant mixed in the sludge and to send a sludge sample to the lab. If they find coolant they would fix the car, but if they dont find any coolant, then I have to pay for the tear down $600 plus what it costs to repair/replace engine because then the reason is neglect.
I asked if neglect or coolant leaking were the ONLY reasons sludge would be present and they said yes.
My coolant levels were normal, and the service rep pretty much told me that the sludge was black, not milky yogurt looking (which would indicate coolant in the oil)
but they still need to do the tear down, just in case.
I questioned this and the mgr is playing good cop "wont do this dealership any good if customer unhappy" "GM requires this" "we want to help you" I dont know if this is all just a song and dance they do with everyone.
I dont know why they cant get sample from oil pan.
I have not yet called the 1 800 number.
I am getting a sample of the sludge myself.
The 60000 mile timing belt will be replaced when they fix/replace engine.
Here is my advice (what I have learned):
1.Use a synthetic oil, a good one and good filters. If you go to a lube place, bring your own oil and filter.
2. Change your oil at 3000 no matter what the Owners Manual says. I could have been better about my oil changes.
3. Get all the maintenance records from anyone you buy a used car from at they time of the sale or say "No deal" This warranty is not good without them.
4. If you are going thru a lot of coolant, get your car to the shop asap, it could be leaking into the engine.
Sorry so long, I dont want this to happen to anyone else. I see alot of posts here saying they change oil every 7500 miles and I cringe,

OK I was pretty upset when I wrote the above post. I want everyone to know I LOVE MY 2007 AVEO. It is a zippy little car with tons of space inside. I have transported my 3 Golden Retrievers and my Chihuahua (all are rescues) all at the same time and one time I even transported three 5 ft palm plants. The seats are made of durable material. It gets good gas milage, about 26-27 MPG in the city, much better on the highway. Also, and this is important to me, it has front wheel drive. It will stop on a dime. I have never slid in the rain when the brakes were applied in the AVEO. I had a Jeep Liberty Limited Edition with all the bells and whistles and in the rain, the wheels locked up a few times and the last time, I rear ended someone. It was totaled and thankfully no one was injured. I rented an AVEO and fell in love with the little car so I bought one and never regretted it.
That said, I went to the dealership this morning and talked to my service rep. He has always been super nice and I truly believe he wants to help. Maybe the manager is the same way, and I shouldn't have said the "good cop song and dance" thing above until I know for sure. GM, not loving them so much- mainly because they took bailout money, my tax dollars, and got in bed with the govt.
I am ticked off a Enterprise car sales for not passing on the service records.
Got my sample straight from the top of the motor, black coal like looking chunks. I was mortified. I should hear something today on what the lab they used says. Regardless of what they find, I wish I would have changed the oil every 3000.
Also, under the advice section of my post above, I said to use synthetic oil, my service rep says they use valvoline not synthetic, so I need to research that a little more. Still get good filters and change every 3000.

As far as synthetic is concerned, go for it. However, you must continue to use it as it shrinks the seals, so going from synthetic to regular oil will likely cause leaks. If the dealership/GM is giving your grief, try out some Seafoam in the interim and see if that helps your problem. it only costs 10-20 bucks and could save you 1000.

Thanks for your post but...Motor is torn down and we are waiting to hear from GM on whether or not they will pay for it. I authorized the service rep to start on repairs last Friday and they are waiting on parts to come in. I did not want it just sitting there waiting for GM to make a decision.
