So what kind of coolant goes in an LR3? I know the owners manual says Castrol SF, which is no where to be found. O'reilly's can get Pentosin SF, but is it the same? They say it's violet and the stuff I've got now is kind of pink or maybe orange. I've seen the pink Jag stuff, but I don't really want to pay extra for Jag or Rover antifreeze and I'd really like to be able to buy it local, which neither of those dealers are. I've also seen a post or two say dexcool, but I'm not sure if I believe it.
