Redline makes some great products. I have used their manual tranny oil in my cars with excellent results. I think it is way too expensive to use for regular oil changes.
What weight oil did you get? Unless it's less than the 5-40 Rotella like a 0-30, it's not going to do much more for you at start-up. That is, unless it's more viscouse at start-up temperature and gets flowing faster, there won't be a difference.
If it's heavier like a 10-40 or 20-50, it certainly won't help at startup.
As far as HP, you may pick up a tiny bit, but it would not be noticeable over another synthetic of similar weight. You would probably notice a bigger difference in power on a cold day from the denser air.
