2007 LR3

i have a bunch KF this left over from when I owned a Subaru WRX STi. Okay to use in my LR?

 

Land Rover calls for the "Dot 4 LV" fluid, which Pentosin also makes, however I really think its just a gimmick. These vehicles use the same ABS/DSC/ASC units that many other Euro vehicles use and Super Dot 4 works just fine. Super Dot 4 isn't an "ESL/LV" (low viscosity) fluid, but does have a higher boiling point.
You will be just fine.
