DOT 4 vs DOT 4 LV (Low Viscosity)
So BMW TIS and RealOEM call for DOT 4 LV but my dealer don't have it and say even their own techs only use the regular DOT 4.
Has most of you just used regular DOT 4 and have been good? The way it's worded in TIS seems like they really want you to use LV fluid. |

Ages ago, somewhere I now can't find, I read that LV has a way higher boiling point than standard. Also lower viscosity for SC, ABS etc to work a bit easier... I'd go for LV every time anyhow; no sense skimping on brake stuff, I think.

Ok well update, the original fluid dealer sold me does say Low Viscocity on it. But the part number they told me it was didn't match to LV when I searched. T he dealer guys said by email they only use DOT 4 my god do they have no idea what they talk about sometimes. All good now guys! |

They don't recommend doing track with LV but then BMW says LV only or it can fuck up ABS/DSC systems. ABS/DSC system isn't cheap so it's why I'm making sure I only use LV but hope I can still do a few track/auto cross fun. If not people who used regular DOT 4 all around have they had issues, I guess not either... I don't do serious tracking but I do go at some small tracks and drags for fun. |

BMW dealers should only be using LV. Lots of OEMs don't specify LV fluids despite being equipped with DSC. Toyota and Mazda still specify DOT 3 fluids in some of their cars |

Она имеет лучшую текучесть при низких температурах (кинематическая вязкость при 40С 700 mm2/s). У DOT 4 - при 40С 1400mm2/s. |
