Today, 6 years after buying the Prizm I have 235,4xx miles on the clock. The Camry is at 204,xxx miles and is due for an oil change this month.
Consumption is still the same, a quart every 2000 miles give or take. I'm out of Havoline, so I'm using Pennzoil or Quaker state in both of these cars. I'm almost out of Toyota filters, and have used all of my Advanced Auto house brand filters, so I'm looking for more filters in the stash.
I did a ring soak in the Prizm last weekend to see if it improved the oil consumption issues. I don't expect miracles. But I was doing a tune-up anyway, so I put 2oz of MMO in each cylinder and let it sit overnight. I removed the ignition fuse 24 hours later and with a towel over the open holes, spun the engine over before I put in new plugs, cap, rotor and PCV valve.
I put the other 1/2 of the MMO bottle into the crankcase and ran the car for about 20 minutes getting the oil up to temperature before changing it, letting it drain for 8 hours or so and refilling with Quaker State 10W40.
I don't really expect the consumption to drop by a great deal. But if it does, I'll repeat this with oilBabe's Camry later this month.

Just rolled over to 159K today, I purchased it 99 weeks ago with 106k on the clock.
I've been running Mobil 1 5W30 with a change every 4 months, current fill is on about 5 months and 9400 miles.
From the records, the previous owner did either Chevy dealership service every 3-5K and then a local lube and carwash at about the same intervals with Mobil 5W30 or 10W30. I might use a quart in the 8-10K mile interval.
I'm switching to the M1 EP when I hit 160K and going for 15K or 6 month intervals.
Oh, and I use Purolator filters.

Let's see, three years later, give or take.
Now at 217K on the clock. Tried the M1 EP for a about 18 months without drama. Did the same thing with Oilbabe's 2002 Camry, now at 178K miles for a while.
Both cars are now back at conventional oils at 5K intervals. Well, the Camry has Supertech synthetic so I'm not out there changing oil in the winter, so it's going 4 months, or about 8K miles until spring. Oilbabe is at about 2K/month usage, and the Prizm has dropped from about 25K/year to about 18K/year as I'm doing more on-site work and taking the train to this customer's site instead of driving the entire St. Louis metro area.
Living in the apartment for the past about 6 months has curtailed much of my tinkering with cars. However, oilbabe and I found a home and will close on 1/25 on our 2700 square foot shack.
First time ever that I owned a home with an attached three car garage.
Let's add a bit to this, since I cut myself off.
I've been using mostly Havoline 5W30 and 10W30 in the warmer weather. I've also used Advance Auto Oil as well on occassions. Both cars are now using about 1 quart every 2000-2500 miles and are on 5K intervals.
I stopped using synthetic during the warmer months due to the consumption. I did use it in oilbabe's Camry just because I didn't want to do a winter oil change while in the apartment complex. (Strangely, there is no prohibition regarding doing such work in our lease.)
Using Purolator, Advance Auto, Supertech and the left-over Toyota filters now that I traded the Scion tC for the Sienna.
