I am doing an oil change next weekend and will send the sample of the Pennzoil Ultra in to Blackstone for a UOA. It will be the first sample with that oil, and it will have about 5000 miles on it. Will be interesting to compare with the Redline.
There has been some buzz on the Bob Is The Oil Guy website that there is some kind of new replacement coming for the Ultra. That may mean some good close out pricing on the current formula, provided you can find any. If you could find a 5 qt. jug for $25 or so I would buy a few.
I'll report my lab results when I get them.
