Cosworth Full Synthetic

[newbombturk]

Hi Fellas I'm new to the board but have been a long time lurker. In any cae, I have recently purchased a 2006 Mazda 6 and just changed out the original factory oil fill at 4100 mi. I replaced the cannister oil filter setup with a spin on factory system. Filled it with 4.5 qts. of Mobil 1. I've never used full synthetic before and am going to use it and see if I notice any discernable results over time.
My ques. is related to other 5w-20 5w-30 full synthetic oils. Has anyone yet obtained and used the Cosworth Full synthetic oils? Feedback appreciated.

I have never used this oil and most likely never will since it is priced higher than Redline. Here is a VOA of their 5w-40.
