So would this Shell (here in Australia) be the same as the Pennzoil euro?

I've been using Redline ester-based High Performance 5w-30 & 40, changing every 6-8K km. I do around 12 tracks days a year plus a few trips to country/mountain roads where we can be going full-on for 70km stints. The Redline is harder to source & cost isn't a concern if it's better as I'm keeping the car forever
