Burning Oil

Add my name to the list of people whose 2006 RAV4 is burning oil. For me, it started when my 2004 4-Cylinder reached about 78000 miles, so I am lucky it started so late. When I checked my oil at 78,000 miles I saw it was off the dipstick and it took 2 quarts to fill it up. Since my car was purchased as a Certified Used car, I have a 100,000 mile warranty.

I took the car to my dealer and we are running the 5,000 mile oil consumption test. I am now about 4300 miles into the test and so far the dealer has had to add about 1.4 quarts of oil. I would estimate that at the end of the test the car will burn a bit under 2 quarts of oil in 5,000 miles. So, does that mean my car meets factory specifications and therefore there is no claim I can make under my 100,000 warranty?

If that is the case I think my best bet is change the oil every 3,000 miles instead of 5,000 miles an always carry oil with me and check the level every time I fill up with gas.

Any comments would be appreciated. I can see I am not the only owner out there with this problem!
Thanks!
Bill

Do you know why I4 burns oil? Did you replace PCV? Did you go over 5000 miles OCI?
If oil rings are sticky, you can free them by using cylinder soaks with MMO or Kreene. It may take several times to free them. I did that in my corolla and it helped. Google is your friend.

Bill, I don't know about Toyota specifically but most manufacturers say that apprx 1000 miles per quart consumed is considered "acceptable" and therefore they won't do anything further. In your case is appears you're getting just over 3000 miles per quart so I doubt Toyota will deem it a warranty issue.

There no real reason to change your oil sooner than normal, just remember to check it periodically and top-up as needed.

It's actually my sister's, but I'm the family wrench.

An emissions test would tell you where the oil is going, but it could be getting burned up because of faulty PVC, rings, etc or it could be turning to sludge. Both conditions are bad for the long term life of that motor.

Yes, I have a 2006, sorry for the typo above. Also, thanks for the input. I will talk to the dealer more about this - ask about the PVC and rings and see if I can do anything. I'll check my oil every time I fill up now. Hope they can help me. This must be pretty common. I don not do any kind of extreme driving, just take a long trip each winter to Arizona from my home in the Seattle area. I drive the RAV4 about 16K miles per year and am hoping to get 200K out of it.

Oil consumption has no effect on engine longevity as any driver of older Saturn or 1998-2002 Corolla can tell you, unless you forget to check the oil level.

But, it is a major nuisance. This why I'm actively treating the early stages in my corolla.

Yea, oil consumption is not the problem. It is a symptom of another problem. Whatever that may be, I don't know, but it shouldn't be happening.

For the record, Toyota specs 1 liter/2000 km or 1 qt/1200 miles in TSBs for engine replacement due to excessive consumption.
