Gabe79 410 Report post Posted January 5, 2019 (edited) I've read we need DOT4 Low Viscosity, but can't find any such examples in Repco, or Supercheap. Fuchs seems to make something that fits that specification though. Penrite has a DOT 4 ESP, but I can't found that for sale in NZ. Castrol's website suggests I can use this: Castrol Brake Fluid DOT 4 Or should I go buy some from the dealership? EDIT: The MSDS for Castrol Response Brake Fluid Super DOT 4 says it is lower viscosity for ABS applications... Edited January 5, 2019 by Gabe79 Quote Share this post Link to post Share on other sites
Eagle 1662 Report post Posted January 6, 2019 The only brake fluid ive ever used in dozens of BMW's have predominately that Castrol Super DOT 4 or Motul RBF600 on the track. Get the Castrol. 1 Quote Share this post Link to post Share on other sites

andrewm 236 Report post Posted January 6, 2019 Agree, I use the same. Castrol response/react dot 4 for daily drivers - its a good deal for the temperatures it can handle. 1 Quote Share this post Link to post Share on other sites
