Saw this the other day. Anyone using (with the S)? Is it any good? Where can I buy them?

thanks.

 

You should only be using BMW "blue" coolant in the R56 S engine. If you mix coolants you take the risk of coolant gelling and other precipitates. Even if you flushed the system, you would have to be ABSOLUTELY sure there is no old coolant left in the cooling system. Why take the risk for such a miniscule potential gain?

 

I use Redline Water Wetter in all my engines...

 

I have used the product in my Ducati 916. It cooled the engine just as good as the Ducati recommended brand. I never saw remarkable temp drop or any horsepower gains as hinted to on the web site. The ONLY advantage I realized from the product is that it was "track safe" but not on all tracks I must add. I am not a scientific tester, nor a lab that can certify my personal findings, just my $0.02.
