New to the forum and I thought I'd contribute my own UOA from Blackstone for my 2001 Chevrolet Prizm. Don't know if any readings are different than they should be because it has a known problem of stuck piston rings and burns a lot of oil. I have used additives such as stop leak, sea foam, and the Restore additive known for very high lead and copper which is why those readings were so high. Have since switched to Valvoline MaxLife 10w40 and let them know I am doing so and that the Restore additive had been used so they now have me checking back at 7,500 miles.
