Sorry about posting misinformation. I believe I had read it in a BMW brochure some time ago. I guess it's about as true as the F10 M5 having side width adjustable lumbar or the Z8 having an LSD! I'll double check my facts next time.
On a separate note, has anyone changed their power steering fluid to Redline D4 ATF? With a flash point of degrees, that has to be higher than the Pentosin. Pentosin only shows an operating range of up to 130 degrees C (266F), no flash point rating as a base of comparison. I can't find an operating range on the Redline D4 on their site. Perhaps it would be more resistant to foaming?

I didn't think D4ATF was interchangeable with CHF11S.

It is shown on Redline's website as suited for power steering fluid application for the M3.

but will BMW feel the same way if you have PS problems. i can own an oil/lube company and print anything i want in terms of what applies in what service. i run redline in my dodge rear axle, front axle, t-case and 6 speed, so I support their stuff. but what makes it so - just because they print it on their literature. just playing devil's advocate with you. are you running it now? if so, for how long? i'd like some longer term data before considering alternatives.

Yeah...might not be good for making your case in warranty claim. Out of warranty? I'll usually go with redline.

Wow, dodged a bullet with the warranty.

I'm out of warranty, and briefly considered switching to something else, but ended up going back with OEM.

I just had my pump and reservoir replaced a few months ago due to noise. So I'll have the better part of the 2 year parts warranty left. I have a friend that's a redline dealer, so I'll have him order it Monday. I was just curious if anyone has tried it yet.
They don't have a product for everything. As an example they say that their oil doesn't meet the low ash standards (LL-04) for the BMW diesels. They claim to test the lubrication properties before advertising that their products are compatible. I was skeptical that their D6 ATF was compatible with the MTF LT3 my 135's transmission took. After nearly 3 years and 35k miles I still didn't have any issues.
