Actually it was a series of fixes. I had 2-3qts/5000 miles oil consumption in 2003 (made in 2002) Corolla since 6X,XXX miles (forgot the exact number) after a steady diet of dino oil changes every 4000-5000 miles/6 months.

I did a couple of MMO piston soaks that would help for 2000 miles or so and consumption would come back. Than, last summer i did an extra long multi-week MMO soak that partially helped and cut consumption in half. I also started filling oil above the dipstick mark as per the Toyota's TSB for this engine.

Before next oil change this last fall, I did Kreen piston soak and flush and started using Maxlife oil. Small consumption lasted for the first 1000 miles and disappeared since. Time will tell but so far so good (no visible consumption whatsoever) several K miles into the OCI.

Next oil changes will be synthetic to prevent the oil consumption from reappearing.

Not sure what exactly was the fix, maybe a combination, but it worked. MMO piston soaks themself seemed least effective.

It sounds like you may have had some stuck piston rings that loosened up with the repeated cleansing steps. Nice job!

We have the same model year with 89,000 miles, no oil burning. I've heard of it though, even on post 2002 1ZZFE's(as seen here). I hope this doesn't happen to ours. I mainly use Synthetic and I'll keep it that way.

Nice job on getting it done.

I have a '99 Corolla that burns about a quart every 1500 miles. Mobil 1 has seemed to help my consumption. I am interested in reading that TSB on the 1 zzfe that you mentioned. I tried a search but haven't located it; can you direct me in locating it?

Just a thought, but why not stick with Max Life for one more OCI before going to a full synthetic?

Thanks for sharing your experience either way.

I don't see how overfilling will help any consumption or leak problems.
BTW, if you think MMO was the least effective at stopping burning, wait until you use the full synthetic. A real waste in that dept!

LOL, I'm doing both! Maxlife 10W30 synthetic will be the first synthetic oil. This is the FAR oil from back then. This will be a consolidation phase not unlike chemotherapy. After that is gone, I've got a stash of various synthetic oils bough on clearance or deep rebates. That would be considered a maintenance phase.

Overfilling lowers oil temp, lowering high temp deposits on pistons/rings.

Synthetic may not fix oil consumption but will certainly avoid it from recurring due to piston/ring deposits due to oil oxidation.

Both applicable only in susceptible engines with high piston temps.

It was likely the Maxlife oil that helped to eliminate the oil consumption not the MMO or Kreen.

The main problem is the clogged oil holes in the pistons. So, the oil can't move, and it burns.

yes, I knew that and thought I was fighting a loosing battle. Now, I have a hope.

Overfilling may INCREASE oil temps. The crank , rods, and pistons are shearing more oil. The film on the pistons/ bores/ and rings is the same with high or low oil levels. The temps there won't change. If any extra oil did get in there, it would result in more oil use, and probable carbon build up.
A synthetic oil won't fix worn bores or rings.

Don't agree.
Raising the oil sump level will reduce oil temp's, by both increasing the time it takes for oil temp's to rise and the maximum oil temp's acheived.
The disadvantage is a possible increase in oil aeration but that would be very much engine specific.
