The oil consumption on my (2) 91 Corsicas, 2.2L, 150,0000 and 190,000 went from (1)qt every 300-500 mi to about 1500-2000 mi using a 50/50 mix of 10-30 hi-mileage and 15-40 longlife.
The only other thing I found to reduce consumption that much was a qt of Lucas oil stabilizer at oil change.
Now, the question is, which one of the Pennzoils did the most good for consumption.
