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.

What are the benefits of paying about 75 cents more for quart for a high mileage versus regular Pennzoil ?? or what are exactly the additives?
The HM oil has a big chunk of Boron , more Calcium and Zinc as I remember . I think it's well worth the additional centavos myself .
I think of it as a more gasoline engine friendly HD oil .
Theres a good UOA of it in a Ford with a 400 engine in the other section .
