I don't have a Prius, but I do have experience with worn out engines. When my 05 Civic's engine started to fail and burn oil it was eventually using about a quart of 5W20 every 600 miles, but I was able to go nearly 1000 miles on a quart of 5W30 and it ran noticeably quieter and smoother too. I don't know how much it would have used with 0W20, but past experience tells me that it would have been worse than 5W20. Switching to 5W40 reduced consumption even further to about 1 quart every 1200 miles. Now that it has a healthy engine I use 5W30 and it burns about 1/2 quart between oil changes (4000 miles), which I am not at all worried about.
