New Sludge Articles

Recommended Posts

thanks for posting these articles. I cant believe consumer reports didnt include the corolla in their sludge list. this even happens to people that change their oil regularly so we really need to watch out for this problem. I'll certainly be checking my oil more often for signs of sludging. ;)

I'm using Mobil 1 5W 30. If I get oil sludge, I'll drive the damn car in to the dealaership and leave it there. My bank can repo it.

That first link with the Corolla looks more like a headgasket or moisture issue. Sludge doesn't look like that - can't pull it up with your hand, got to scrap it off with putty knife or similar.

 

Pretty funny - the third like has a photo of a Renault 4 engine - probably made from the 60s and 70s. Gotta love the media.

 

Supposedly the two cars I currently have "known" sludge related issues - used conventional in the Camry (OCI - 3K-5K) and synthetic in the Corolla (OCI 7K-10K) - no problems so far.

Actually, the Toyota sludge is as described in the article. Toyota initially called it "gel" when they first announced their policy because of the consistency being jelly-like.

Yeah - sludge term that everyone is slinging around may not be the best term for it - "Oil Gelation" sounds better.

 

But I only mentioned that it looks exactly like water/coolant in motor oil (mayonnaise like consistency, lighter color). Could be an issue with the PCV system that was used in certain years to meet emission regs. Why only some people were affected and not others with the same model years makes it a mystery for me.

regarding Corolla sludge, quite a few complaints of sludged Corollas on the Autosafety site at www.autosafety.org. Never understood why Toyota did not include all models under their sludge policy and why it was limited to certain years. You have to prove proper maintenance to be covered, so it is def. something Toyo should take care of when sludge occurs with proper oil changes.

I have a headache from reading about engine sludge on the Internet...maybe I have a brain tumor :o

 

^^^^That's what I think about this sludge issue.

 

I will take two Aspirins and follow these rules:

 

Oil changes within manufacturer's recommondations, beter a 100 miles before the interval than after

 

Keep all oil change receipts

 

Make sure oil receipts states car mileage, oil grade and fitler part no.

 

Check oil between oil changes regularly, more or less every gas tank, depending on oil consumption.

Toyota recommended 5000/7500 mile oil changes on older models depending on driving conditions (5000 on newer regardless of driving conditions). There have been reports that these intervals are too long for these engines and that 3,000 mile oil changes are more appropriate. So I would say DON'T follow Toyota's recommendations - use the tried and true 3000 mile interval to play it safe.

My ’98 Corolla sludged at 33K miles while it was within powertrain warranty despite regular maintenance within the specified time intervals. A Toyota dealership brought this to my attention, however didn’t explain to me the consequences and next course of action. I kept driving the car and continued with regular oil changes. The engine blew up at 50K miles possibly due to over consumption of oil. I spent 5K and had the engine replaced. The car was out of PT warranty by 12 days.

 

I sent in the oil change receipts and proof of maintenance history to Toyota and requested that Corolla should be included in the SPA program for reimbursement. They sent a letter saying that I should have properly “maintained” my car and offered me a 1K discount towards purchase of a new Toyota.

 

I have now bought a Honda CRV and was told that my first oil change was due at 10K miles.

 

I now find an increasing number of Corolla owners with this problem.

I hate to hear of toyota walking over people like that, I wish people would get lawyers or do whatever they had to do to fight harder against toyota instead of allowing themselves to be sluffed off. toyota isnt going to nicely ask to replace a sludged motor, theyre going to do everything possible to keep the penalty of paying for it in the owners lap and they will get away with it every time if the owner doesnt fight.

 

from the description it seems the oil was possibly changed every 3k miles, if so that wouldnt be neglegent maintanance yet it still sludged. I dont know that I would have paid $5k to replace the motor for a car that likely wasnt worth $5k by that time. if that was me though I would have atleast left a bbb complaint for toyota about that, if not talked to the news stations about it also.

I did everything I could do - complained to BBB, wrote to Toyota's CEO, posted my story on edmunds, complaint station etc, but didnt take a legal stand. Toyota's response was that I was out of PT warranty and they would do nothing about it. When I called them, I was told Corolla is not included in the SPA program since Corolla's have never had any problems. I guess I was the first one to be unlucky.

 

The authorized Toyota dealership that replaced my engine refused to admit that sludging was involved that blew the engine. My case was extensivley discussed in cartrackers.com. The link isnt working anymore though.
