After re-reading the question, I must admit I missed the black airfilter!!! If that sucker was choking.....then it may even have been pulling oil and oil vapors hard throught the crankcase venting...so I agree with maja and haley10
Why did this car stop burning oil??

Sorry had to move this from the other post, I didnt realize it was a accidental double topic post.
Was the previous oil by any chance Valvoline... Sorry Tall Paul I couldnt resist.
Changing the air filter can help it was really stopped up.
You didnt by chance change the PCV valve did you?
It may be thicker than your previous oil even if they were both 10W-30. This will reduce consumption. Check the Vicosity at 100C (212F) on their spec sheets or in th Virgin Oil Analysis here.
You have had some deposits in the cylinder ring land and you have cleaned them out. Mobil DriveClean is a Group I oil so it has a fair amount of Aromatics which can act as mild solvents and it also has a good dose of calcium (Detergent). Maybe the the two together managed to get rid of the deposit.
If you had asked before the change I would have told you to try a 15W-40 HDEO like Mobil Delvac 1300 for the same reasons. LOTS of Detergents and its thicker.

My gf has a 1994 Toyota Camry, with 196k miles on the engine. For the past 30k miles, the engine burned a quart every 1000 miles, which was not to bad.
Recently, i made a few changes:
1. replaced plugs and wires
2. New air filter (old one was BLACK, at least 3 years old)
3.she was using FRAM filters for the vehicle life and i put on an the first ACDELCO during the last oil change.
4. started using mobil drive clean around 15k back.
The car no longer burns any oil, at least not at this oil change cycle. Right now its summer in NY, and its been around 80-95 degrees and this car usually burns oil a bit faster, but it has not moved on the stick, and its been 2500 miles. Any ideas?? i dont know whats causing this miracle.

sorry for a double topic post, i have a 56k modem and when i get alot of slow-down i tend to click again at the same buttons!
It is possible the new oil cleaned the ring grooves and rings and allowed a better seal, so less consumption. I for sure have seen this with AutoRx.
I think the new air filter made the biggest benefit here. There was a post not too long ago about this. Has something to do with less restriction through the intake tract, thus, lessening the pressure to try to pull through the ring packs. The other changes also helped some.
