I have the same problem as LibraryJim - I have just had the back and forth between the dealer and Toyota customer service line on my 2002 Toyota Corolla CE - I have reported the burning oil problem to my oil change places and my dealer when i took it in for the 60,000 mile check up. They didn't believe me and blamed what they thought was poor maintenance on me. I insisted that I still had an ExtraCare warranty so was wondering why they wouldn't examine this. They put dye in the oil to see about a leak. there was no leak. They found a transmission leak and fixed that - then my car proceeded to burn 3 quarts of oil after a 700 mile drive immediately following the oil change/transmission leak fix.
Turns out I do have sludge in my engine. I was able to give documentation for 7 oil changes since it was new until 64,000 miles (where it is currently) but Toyota Extra Care does not cover engine sludge, evidentally. They denied me before waiting for the receipts that i did have, which appears disingenuous to me.
So, first I wanted to add my experience but second I had a few questions:
1) Are others having similar experiences with this generation corolla? Unsolicited, one of my oil change places mentioned that toyota would settle if i hired a lawyer because they were having these problems with corollas
2) If folks have been able to get ExtraCare to cover this, how many oil change receipts were they able to find?
3) If there are some gaps in my record of oil changes during which time i can prove that i was buying and putting new quarts of oil in my car between changes because oil was burning so quickly, does this new oil act as a sort of oil change? I wondered if i could use this as an argument.
But sadly, I am like LibraryJim in that I won't be getting this fixed on my dime. I bought this car prior to entering a PhD program so that i wouldn't have to worry about car costs while earning only student stipend. Well, this new car didn't last me through graduate school. So, no cash to fix it and no coverage extended to me on my young, lower mileage, extended warranty vehicle. Toyota is doing something wrong. Thanks for any insight that folks could offer!
