Does anyone know the required brake fluid for the Gen IV?
Yes, I flushed our old '10MY Outback with this very product. Also, my brother's '06MY Impreza with no problems what-so-ever. BTW all brake fluid is synthetic.Guess it is the same as last Gen. Thanks.
Is anyone using the Valvoline Synthetic DOT 3 and 4?
The recommendation would be to use Dot 4 because of the higher boiling point and then use something like Prestone synthetic which indicates on the bottle it can be used with any brand or any type either Dot 3 or Dot 4. Case closed. And it's literally absurd to think that you couldn't mix any brand together any dots together if you think you'd run into a problem I dare you to show me. It wouldn't happen. But it is better to just go with a bottle that confirms it's fine and don't worry about it. But like others have pointed out Common Sense would say it would not matter. If you take your car to an oil change shop they have no clue what type/brand of fluid you have in there and they're going to top it off with whatever they have. End of story. Don't be sheep and follow manufacturer's suggestions that are going to have you with your tail between your legs running back to them for help.This note in the OB owner's manual puzzles me:
"Avoid mixing DOT 3 and DOT 4 brake fluids even if they are the same brand."
If DOT 3 is adequate then what harm could there be by adding a DOT 4?
Also, what comes from the factory? Seems the only "authorized" fluid that can be used to top off the reservoir would be what Subaru sells through the dealer's parts department.
