Mate to be honest I don't think you will feel a massive performance increase.
The techs that built the Csl must have genuinely thought that atf was sufficient for the power steering system and stuck to that.im not an oil guru so I can't comment further all I can say in my opinion is that the power steering works far less then the smg pump system.smg gets a lot hotter has far more functions as in its gotta control 3 hydraulic valves so it would be the obvious choice for that system.whereas your pas system is basically a loop around the rack.secondly the rack sits below the engine and it stays cooler as the cold air passes it and once moving steering is under less pressure to work as opposed to standstill turning this could be a factor in not using chf 11s.you would need a technical sheet to compare the 2 oils.its like dot 4 vs dot 5.2 brake fluid higher boiling temps but that will only count if you really abuse the brake system.so summary you could in deed use chf 11s if you felt like you Needed to but I'm sure if Bmw deemed it nesseccary they would have used it in first instance.dont forget they spent I think £95k developing the Csl and sold them at a loss of around £65k to get them outta the door.the techs we met who built the cars said if they had their way it would be so much more track orientated but the average car enthusiast had to be able to drive it.anyone agree?
As I said I'm not an oil guru and I've not noticed any benefit switching brands
