Search the UOA section in Bob Is The Oil Guy Forum for posts under my name.
There are a couple of results with Redline in my 2009 370Z. I am currently running Pennzoil Ultra and will post the UOA in a few weeks when I do the next change and get the Blackstone results back. One immediate difference is that as I am approaching the 40K mileage point, oil consumption with the 05W-30 Ultra has been less than a half quart in 4000 miles. Using Redline from the 5000 mile to 35,000 mile point, I was using about 1.25 quarts per 5000 mile OCI. Either the engine is finally settling down, or the Ultra has made a difference in consumption. If I get comparable numbers on the UOA I may switch to Ultra, it is considerably less expensive per oil change.
