Thanks for that additional info. That is an oil I never would have considered.It is not just the oils you posted as my car had some varnish and Redline Performance Euro cleaned it all off on the first use/3,000 miles. I will not be using that oil again as I can get HPL cheaper and it appears to be a better oil to top it off. Redline has priced themselves out of my market.
A good way to look at it is the net $ spent. Once and done with Redline could be cheaper than 4+ OCI required with the other choices.
