[QUOTE="Johnny O, post: 1001577, member: 61743"] Actually that was comparing the same oil (Mobil 1 0w-30) run for 5000 miles and then 7500 miles. The wear metals took a big jump when the oil was run 2500 more miles and Blackstone Labs recommended that I keep it to 5000 miles if I used that oil. I have always used Motorcraft for 5000 mile OCI's and Mobil 1 or K&N filters for 7500 mile OCI's. Usually Mobil 1. My Dad's '04 Cadillac holds 7.5 quarts and once just for ***** and giggles we ran Pennzoil Platinum until the oil life monitor was down to 2%, this was over 12,000 miles, sent it in for a UOA, and it came back fine. I usually change the Caddy's oil every 10k since then and when Mom and Dad get back from Florida in a couple weeks it will probably have 200,000 miles on it. Looks and runs like new and doesn't burn a drop of oil although it did blow a head gasket on their way back from FL last year. That seems to be common on Northstar Cadillacs once they get upwards of 100k though. The Caddy gets Mobil 1 if Dad buys the oil and Pennzoil Platinum if I do. [/QUOTE]
