The platinum is still better then most in my opinion but you can order the ultra on their website I believe. I've been using pennzoil for years and have never once had an issue with their products. With all of my previous builds 5 builds in my mustangs and Cobras , I've always used the Dino oil for break in and kept using it up until they came out with the platinum and ultra platinum and then made the switch. Great stuff. After building my engines and running the Dino and then switching to the plat or UP I did notice that the motors always seemed a tad quieter as well as feels smoother. Have yet to send anything out to blackstone but I really don't feel the need to. Were I in an all out race car then yeah, I could see the benefit but for the average home mechanic habitual maintenance intervals is always the key to a long living and happy motor. My 2 cents. But I do love the stuff.
